The STM3240G-EVAL board has four LEDs labeled LD1, LD2, LD3 and LD4 on the
|
|
|
|
board.. These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
|
|
|
|
defined. In that case, the usage by the board port is defined in
|
|
|
|
include/board.h and src/up_leds.c. The LEDs are used to encode OS-related\
|
|
|
|
events as follows:

|
** The normal state is LED3 ON and LED1 faintly glowing. This faint glow
|
2013-12-30 19:42:18 +01:00
|
|
|
is because of timer interrupts that result in the LED being illuminated
|
2011-11-24 02:34:10 +01:00
|
|
|
on a small proportion of the time.
|
|

The STM3240G-Eval has no real on-board PWM devices, but the board can be
|
2012-01-11 17:01:18 +01:00
|
|
|
configured to output a pulse train using timer output pins. The following
|
|
|
|
pins have been use to generate PWM output (see board.h for some other
|
|
|
|
candidates):

TIM4 CH2. Pin PD13 is used by the FSMC (FSMC_A18) and is also connected
|
|
|
|
to the Motor Control Connector (CN5) just for this purpose. If FSMC is
|
|
|
|
not enabled, then FSMC_A18 will not be used (and will be tri-stated from
|
|
|
|
the LCD).

Connector 10 (CN10) is DB-9 male connector that can be used with CAN1 or CAN2.
|
|
|
|
|
|
|
|
JP10 connects CAN1_RX or CAN2_RX to the CAN transceiver
|
|
|
|
JP3 connects CAN1_TX or CAN2_TX to the CAN transceiver
|
|
|
|
|

|
|
|
|
|
CN10 Pin 7 = CANH
|
|
|
|
CN10 Pin 2 = CANL

|
FPU Configuration Options
|
|
|
|
-------------------------
|
|
|
|
|
|
|
|
There are two version of the FPU support built into the STM32 port.
|
|
|
|
|
2018-06-20 20:30:37 +02:00
|
|
|
1. Non-Lazy Floating Point Register Save
|
2012-02-22 19:14:18 +01:00
|
|
|
|
2018-06-20 20:30:37 +02:00
|
|
|
In this configuration floating point register save and restore is
|
|
|
|
implemented on interrupt entry and return, respectively. In this
|
|
|
|
case, you may use floating point operations for interrupt handling
|
|
|
|
logic if necessary. This FPU behavior logic is enabled by default
|
|
|
|
with:
|
|
|
|
|
|
|
|
CONFIG_ARCH_FPU=y
|
|
|
|
|
|
|
|
2. Lazy Floating Point Register Save.
|
|
|
|
|
|
|
|
An alternative mplementation only saves and restores FPU registers only
|
|
|
|
on context switches. This means: (1) floating point registers are not
|
|
|
|
stored on each context switch and, hence, possibly better interrupt
|
2012-02-22 19:14:18 +01:00
|
|
|
performance. But, (2) since floating point registers are not saved,
|
|
|
|
you cannot use floating point operations within interrupt handlers.
|
|
|
|
|
|
|
|
This logic can be enabled by simply adding the following to your .config
|
|
|
|
file:
|
|
|
|
|
2018-06-20 20:30:37 +02:00
|
|
|
CONFIG_ARCH_FPU=y

Only recent GCC toolchains have built-in support for the Cortex-M4 FPU. You will see
|
2012-02-23 22:29:42 +01:00
|
|
|
the following lines in each Make.defs file:
|
|
|
|
|
|
|
|
ifeq ($(CONFIG_ARCH_FPU),y)
|
|
|
|
ARCHCPUFLAGS = -mcpu=cortex-m4 -mthumb -march=armv7e-m -mfpu=fpv4-sp-d16 -mfloat-abi=hard
|

FSMC SRAM
|
|
|
|
=========
|
|
|
|
|
|
|
|
On-board SRAM
|
|
|
|
-------------
|
|
|
|
|
|
|
|
A 16 Mbit SRAM is connected to the STM32F407IGH6 FSMC bus which shares the same
|
|
|
|
I/Os with the CAN1 bus. Jumper settings:
|
|
|
|
|
|
|
|
JP1: Connect PE4 to SRAM as A20
|
|
|
|
JP2: onnect PE3 to SRAM as A19
|
|
|
|
|
|
|
|
JP3 and JP10 must not be fitted for SRAM and LCD application. JP3 and JP10
|
|
|
|
select CAN1 or CAN2 if fitted; neither if not fitted.
|
|
|
|
|
|
|
|
The on-board SRAM can be configured by setting
|
|
|
|
|
|
|
|
CONFIG_STM32_FSMC=y
|
2019-05-27 15:21:52 +02:00
|
|
|
CONFIG_STM32_EXTERNAL_RAM=y

|
|
CONFIG_HEAP2_BASE=0x64000000
|
2012-09-06 01:02:43 +02:00
|
|
|
CONFIG_HEAP2_SIZE=2097152
|
2012-02-28 00:14:43 +01:00
|
|
|
CONFIG_MM_REGIONS=2 (or =3, see below)

|
Configuration Options
|
|
|
|
---------------------
|
|
|
|
Internal SRAM is available in all members of the STM32 family. The F4 family
|
2012-04-07 22:54:45 +02:00
|
|
|
also contains internal CCM SRAM. This SRAM is different because it cannot
|
2012-02-28 00:14:43 +01:00
|
|
|
be used for DMA. So if DMA needed, then the following should be defined
|
2012-04-07 22:54:45 +02:00
|
|
|
to exclude CCM SRAM from the heap:
|
2012-02-28 00:14:43 +01:00
|
|
|
|
2012-04-07 22:54:45 +02:00
|
|
|
CONFIG_STM32_CCMEXCLUDE : Exclude CCM SRAM from the HEAP
|
2012-02-28 00:14:43 +01:00
|
|
|
|
|
|
|
In addition to internal SRAM, SRAM may also be available through the FSMC.
|
|
|
|
In order to use FSMC SRAM, the following additional things need to be
|
|
|
|
present in the NuttX configuration file:
|
|
|
|
|
2019-05-27 15:21:52 +02:00
|
|
|
CONFIG_STM32_FSMC=y : Enables the FSMC
|
|
|
|
CONFIG_STM32_EXTERNAL_RAM=y : Indicates that SRAM is available via the
|
|
|
|
FSMC (as opposed to an LCD or FLASH).
|
|
|
|
CONFIG_HEAP2_BASE : The base address of the SRAM in the FSMC
|
2012-05-28 21:48:26 +02:00
|
|
|
address space
|
2019-05-27 15:21:52 +02:00
|
|
|
CONFIG_HEAP2_SIZE : The size of the SRAM in the FSMC
|
|
|
|
address space
|
|
|
|
CONFIG_MM_REGIONS : Must be set to a large enough value to
|
|
|
|
include the FSMC SRAM
|
2012-02-28 00:14:43 +01:00

Timer devices may be used for different purposes. One special purpose is
|
|
|
|
to generate modulated outputs for such things as motor control. If CONFIG_STM32_TIMn
|
|
|
|
is defined (as above) then the following may also be defined to indicate that
|
|
|
|
the timer is intended to be used for pulsed output modulation, ADC conversion,
|
2012-01-05 00:46:00 +01:00
|
|
|
or DAC conversion. Note that ADC/DAC require two definition: Not only do you have
|
|
|
|
to assign the timer (n) for used by the ADC or DAC, but then you also have to
|
|
|
|
configure which ADC or DAC (m) it is assigned to.
|
|
|

|
|
|
For each timer that is enabled for PWM usage, we need the following additional
|
|
|
|
configuration settings:
|
|
|
|
|
2012-02-28 00:14:43 +01:00
|
|
|
CONFIG_STM32_TIMx_CHANNEL - Specifies the timer output channel {1,..,4}
|
2012-05-28 21:48:26 +02:00
|
|
|
|
2011-12-19 20:24:09 +01:00
|
|
|
NOTE: The STM32 timers are each capable of generating different signals on
|
|
|
|
each of the four channels with different duty cycles. That capability is
|
|
|
|
not supported by this driver: Only one output channel per timer.
|
|
|
|
|
2011-11-22 15:16:38 +01:00
|
|
|
JTAG Enable settings (by default JTAG-DP and SW-DP are disabled):

|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
|
|
change this configurations using that tool, you should:
|
|
|
|
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
2015-06-28 16:08:57 +02:00
|
|
|
see additional README.txt files in the NuttX tools repository.
|
2014-03-03 20:29:27 +01:00

|
|
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
|
|
reconfiguration process.
|
|
|
|
|
|
|
|
2. The server address is 10.0.0.1 and it serves IP addresses in the range
|
|
|
|
10.0.0.2 through 10.0.0.17 (all of which, of course, are configurable).

discover:
|
|
|
|
--------
|
|
|
|
This configuration exercises netutils/discover utility using
|
|
|
|
apps/exmaples/discover. This example initializes and starts the UDP
|
|
|
|
discover daemon. This daemon is useful for discovering devices in
|
|
|
|
local networks, especially with DHCP configured devices. It listens
|
|
|
|
for UDP broadcasts which also can include a device class so that
|
|
|
|
groups of devices can be discovered. It is also possible to address all
|
|
|
|
classes with a kind of broadcast discover.

--
|
|
|
|
|
|
|
|
A simple NSH configuration used for some basic (non-graphic) debug of
|
2017-11-26 13:32:43 +01:00
|
|
|
the framebuffer character driver at drivers/video/fb.c. NOTE that
|
|
|
|
the STM3240G-EVAL LCD driver does not support a framebuffer! It
|
|
|
|
interfaces with the LCD through a parallel FSMC interface. This
|
|
|
|
configuration uses the LCD framebuffer front end at
|
2017-09-17 23:55:15 +02:00
|
|
|
drivers/lcd/lcd_framebuffer to convert the LCD interface into a
|
|
|
|
compatible framebuffer interface.
|
|
|
|
|
2017-11-26 13:32:43 +01:00
|
|
|
This examples supports the framebuffer test at apps/examples/fb. That
|
|
|
|
test simply draws a pattern into the framebuffer and updates the LCD.
|
|
|
|
|
|
|
|
This example also supports the pdcurses library at apps/graphics/pdcurses
|
|
|
|
and the demo programs at apps/examples/pdcurses. This is a good test of
|
|
|
|
the use of the framebuffer driver in an application. Many of the
|
|
|
|
pdcurses demos requires user interaction via a mouse, keyboard, or
|
|
|
|
joystick. No input devices are currently present in the configuration
|
|
|
|
so no such interaction is possible.
|
|
|
|
|
|
|
|
The STM3240G-EVAL does provide a on-board discrete joystick (djoystick)
|
|
|
|
that could be used for this interaction. However, those discrete inputs
|
|
|
|
do not go directly to the STM32 but rather go indirectly through an I/O
|
|
|
|
expander. I just have not had the motivation to deal with that yet.

knxwm:
|
|
|
|
-----
|
|
|
|
This is identical to the nxwm configuration below except that NuttX
|
|
|
|
is built as a kernel-mode, monolithic module and the user applications
|
|
|
|
are built separately. Is is recommended to use a special make command;
|
|
|
|
not just 'make' but make with the following two arguments:
|
|
|
|
|
|
|
|
make pass1 pass2
|
|
|
|
|
|
|
|
In the normal case (just 'make'), make will attempt to build both user-
|
|
|
|
and kernel-mode blobs more or less interleaved. This actual works!
|
|
|
|
However, for me it is very confusing so I prefer the above make command:
|
|
|
|
Make the user-space binaries first (pass1), then make the kernel-space
|
|
|
|
binaries (pass2)

|
NOTE: When I used a recent CodeSourcery toolchain, then toolchain
|
|
|
|
generated an illegal blx to an even address when calling into one
|
|
|
|
of the EABI math libraries. I don't know why this happened or if
|
|
|
|
the probably is repeatable with other CodeSourcery versions. You
|
|
|
|
can try for yourself setting:
|
|
|
|
|
|
|
|
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows
|
|
|
|
CONFIG_CXX_NEWLONG=n : size_t is unsigned int (maybe?)
|
|
|
|
|
2014-09-19 18:12:03 +02:00
|
|
|
3. In addition to the protected mode build, this NxWM configuration
|
2013-12-30 17:04:34 +01:00
|
|
|
differences from the nxwm configuration in that:
|
|
|
|
|
|
|
|
a. Networking is disabled. There are issues with some of the network-
|
2014-09-19 18:12:03 +02:00
|
|
|
related NSH commands and with Telnet in the protected build (see the
|
2013-12-30 17:04:34 +01:00
|
|
|
top-level TODO file). Without these NSH commands, there is no use
|
|
|
|
for networking in this configuration.
|
|
|
|
|
2014-09-20 23:01:50 +02:00
|
|
|
b. The NxTerm windows are disabled. There are also issues with the
|
2019-03-09 18:19:00 +01:00
|
|
|
NxTerm build now.
|
|
|
|
|
|
|
|
NOTE: Those issues have been resolved. However, this configuration
|
|
|
|
has not yet be re-verified with NxTerm enabled.
|
2013-12-30 17:04:34 +01:00
|
|
|
|
|
|
|
c. The initialization sequence is quite different: NX and the
|
|
|
|
touchscreen are initialized in kernel mode by logic in this src/
|
|
|
|
directory before the NxWM application is started.
|
|
|
|
|
|
|
|
4. At the end of the build, there will be several files in the top-level
|
2013-12-29 20:15:08 +01:00
|
|
|
NuttX build directory:
|
|
|
|
|
|
|
|
PASS1:
|
|
|
|
nuttx_user.elf - The pass1 user-space ELF file
|
|
|
|
nuttx_user.hex - The pass1 Intel HEX format file (selected in defconfig)
|
|
|
|
User.map - Symbols in the user-space ELF file
|
|
|
|
|
|
|
|
PASS2:
|
|
|
|
nuttx - The pass2 kernel-space ELF file
|
|
|
|
nuttx.hex - The pass2 Intel HEX file (selected in defconfig)
|
|
|
|
System.map - Symbols in the kernel-space ELF file
|
|
|
|
|
2013-12-30 17:04:34 +01:00
|
|
|
5. Combining .hex files. If you plan to use the STM32 ST-Link Utility to
|
2013-12-29 20:15:08 +01:00
|
|
|
load the .hex files into FLASH, then you need to combine the two hex
|
|
|
|
files into a single .hex file. Here is how you can do that.
|
|
|
|
|
|
|
|
a. The 'tail' of the nuttx.hex file should look something like this
|
|
|
|
(with my comments added):
|
|
|
|
|
|
|
|
$ tail nuttx.hex
|
|
|
|
# 00, data records
|
|
|
|
...
|
|
|
|
:10 9DC0 00 01000000000800006400020100001F0004
|
|
|
|
:10 9DD0 00 3B005A0078009700B500D400F300110151
|
|
|
|
:08 9DE0 00 30014E016D0100008D
|
|
|
|
# 05, Start Linear Address Record
|
|
|
|
:04 0000 05 0800 0419 D2
|
|
|
|
# 01, End Of File record
|
|
|
|
:00 0000 01 FF
|
|
|
|
|
|
|
|
Use an editor such as vi to remove the 05 and 01 records.
|
|
|
|
|
|
|
|
b. The 'head' of the nuttx_user.hex file should look something like
|
|
|
|
this (again with my comments added):
|
|
|
|
|
|
|
|
$ head nuttx_user.hex
|
|
|
|
# 04, Extended Linear Address Record
|
|
|
|
:02 0000 04 0801 F1
|
|
|
|
# 00, data records
|
|
|
|
:10 8000 00 BD89 01084C800108C8110208D01102087E
|
|
|
|
:10 8010 00 0010 00201C1000201C1000203C16002026
|
|
|
|
:10 8020 00 4D80 01085D80010869800108ED83010829
|
|
|
|
...
|
|
|
|
|
|
|
|
Nothing needs to be done here. The nuttx_user.hex file should
|
|
|
|
be fine.
|
|
|
|
|
|
|
|
c. Combine the edited nuttx.hex and un-edited nuttx_user.hex
|
|
|
|
file to produce a single combined hex file:
|
|
|
|
|
|
|
|
$ cat nuttx.hex nuttx_user.hex >combined.hex
|
|
|
|
|
|
|
|
Then use the combined.hex file with the STM32 ST-Link tool. If
|
|
|
|
you do this a lot, you will probably want to invest a little time
|
|
|
|
to develop a tool to automate these steps.

STATUS:

2014-10-11: This worked at one time, but today I am getting a

failure inside of the GCC library. This occurred with the

computations at the end of touchscreen calibration. The

NuttX code seems to be working correctly, but there is some

2. This example assumes that a network is connected. During its
|
2012-01-02 19:22:19 +01:00
|
|
|
initialization, it will try to negotiate the link speed. If you have
|
|
|
|
no network connected when you reset the board, there will be a long
|
|
|
|
delay (maybe 30 seconds?) before anything happens. That is the timeout
|
|
|
|
before the networking finally gives up and decides that no network is
|
|
|
|
available.

8. This example supports the watchdog timer test (apps/examples/watchdog)

|
2012-04-17 00:43:40 +02:00

|
|
|
|
|
|
CONFIG_WATCHDOG=y : Enables watchdog timer driver support
|
|
|
|
CONFIG_STM32_WWDG=y : Enables the WWDG timer facility, OR
|
|
|
|
CONFIG_STM32_IWDG=y : Enables the IWDG timer facility (but not both)
|
|
|
|
|
|
|
|
The WWDG watchdog is driven off the (fast) 42MHz PCLK1 and, as result,
|
2012-04-27 00:10:40 +02:00
|
|
|
has a maximum timeout value of 49 milliseconds. For WWDG watchdog, you
|
2012-04-17 00:43:40 +02:00
|
|
|
should also add the fillowing to the configuration file:
|
|
|
|
|
|
|
|
CONFIG_EXAMPLES_WATCHDOG_PINGDELAY=20
|
|
|
|
CONFIG_EXAMPLES_WATCHDOG_TIMEOUT=49
|
|
|
|
|
|
|
|
The IWDG timer has a range of about 35 seconds and should not be an issue.

11. USB OTG FS Host Support. The following changes will enable support for
|
|
|
|
a USB host on the STM32F4Discovery, including support for a mass storage
|
|
|
|
class driver:
|
2012-08-30 20:18:47 +02:00
|
|
|
|
2014-02-28 23:28:28 +01:00
|
|
|
CONFIG_USBDEV=n : Make sure tht USB device support is disabled
|
|
|
|
CONFIG_USBHOST=y : Enable USB host support
|
|
|
|
CONFIG_STM32_OTGFS=y : Enable the STM32 USB OTG FS block
|
|
|
|
CONFIG_STM32_SYSCFG=y : Needed for all USB OTF FS support
|
|
|
|
CONFIG_SCHED_WORKQUEUE=y : Worker thread support is required for the mass
|
2012-08-30 20:18:47 +02:00
|
|
|
storage class driver.
|
2014-02-28 23:28:28 +01:00
|
|
|
CONFIG_NSH_ARCHINIT=y : Architecture specific USB initialization
|
2012-08-30 20:18:47 +02:00
|
|
|
is needed for NSH
|
2014-02-28 23:28:28 +01:00
|
|
|
CONFIG_FS_FAT=y : Needed by the USB host mass storage class.
|
2012-08-30 20:18:47 +02:00
|
|
|
|
|
|
|
With those changes, you can use NSH with a FLASH pen driver as shown
|
|
|
|
belong. Here NSH is started with nothing in the USB host slot:
|
|
|
|
|
|
|
|
NuttShell (NSH) NuttX-x.yy
|
|
|
|
nsh> ls /dev
|
|
|
|
/dev:
|
|
|
|
console
|
|
|
|
null
|
|
|
|
ttyS0
|
|
|
|
|
|
|
|
After inserting the FLASH drive, the /dev/sda appears and can be
|
|
|
|
mounted like this:
|
|
|
|
|
|
|
|
nsh> ls /dev
|
|
|
|
/dev:
|
|
|
|
console
|
|
|
|
null
|
|
|
|
sda
|
|
|
|
ttyS0
|
|
|
|
nsh> mount -t vfat /dev/sda /mnt/stuff
|
|
|
|
nsh> ls /mnt/stuff
|
|
|
|
/mnt/stuff:
|
|
|
|
-rw-rw-rw- 16236 filea.c
|
|
|
|
|
|
|
|
And files on the FLASH can be manipulated to standard interfaces:
|
|
|
|
|
|
|
|
nsh> echo "This is a test" >/mnt/stuff/atest.txt
|
|
|
|
nsh> ls /mnt/stuff
|
|
|
|
/mnt/stuff:
|
|
|
|
-rw-rw-rw- 16236 filea.c
|
|
|
|
-rw-rw-rw- 16 atest.txt
|
|
|
|
nsh> cat /mnt/stuff/atest.txt
|
|
|
|
This is a test
|
|
|
|
nsh> cp /mnt/stuff/filea.c fileb.c
|
|
|
|
nsh> ls /mnt/stuff
|
|
|
|
/mnt/stuff:
|
|
|
|
-rw-rw-rw- 16236 filea.c
|
|
|
|
-rw-rw-rw- 16 atest.txt
|
|
|
|
-rw-rw-rw- 16236 fileb.c
|
|
|
|
|
|
|
|
To prevent data loss, don't forget to un-mount the FLASH drive
|
|
|
|
before removing it:
|
|
|
|
|
|
|
|
nsh> umount /mnt/stuff
|
|
|
|
|
2014-02-28 23:28:28 +01:00
|
|
|
12. By default, this configuration supports /dev/random using the STM32's
|
2012-09-29 22:34:25 +02:00
|
|
|
RNG hardware. This can be disabled as follows:
|
|
|
|
|
|
|
|
-CONFIG_STM32_RNG=y
|
|
|
|
+CONFIG_STM32_RNG=n
|
2013-12-29 20:15:08 +01:00
|
|
|
|
2012-09-29 22:34:25 +02:00
|
|
|
-CONFIG_DEV_RANDOM=y
|
|
|
|
+CONFIG_DEV_RANDOM=n
|
|
|
|
|
2014-02-28 23:28:28 +01:00
|
|
|
13. This configuration requires that jumper JP22 be set to enable RS-232
|
2012-07-12 18:11:43 +02:00
|
|
|
operation.
|
2012-02-03 00:14:54 +01:00

nsh2:
|
|
|
|
-----
|
|
|
|
|
2012-03-13 20:21:04 +01:00
|
|
|
This is an alternative NSH configuration. One limitation of the STM3240G-EVAL
|
2012-02-03 00:14:54 +01:00
|
|
|
board is that you cannot have both a UART-based NSH console and SDIO support.
|
|
|
|
The nsh2 differs from the nsh configuration in the following ways:
|
|
|
|
|
|
|
|
-CONFIG_STM32_USART3=y : USART3 is disabled
|
2012-03-13 20:21:04 +01:00
|
|
|
+CONFIG_STM32_USART3=n
|
2012-02-03 00:14:54 +01:00
|
|
|
|
|
|
|
-CONFIG_STM32_SDIO=n : SDIO is enabled
|
|
|
|
+CONFIG_STM32_SDIO=y
|
|
|
|
|
2012-02-27 20:50:35 +01:00
|
|
|
Logically, these are the only differences: This configuration has SDIO (and
|
2012-02-12 03:53:01 +01:00
|
|
|
the SD card) enabled and the serial console disabled. There is ONLY a
|
|
|
|
Telnet console!.
|
2012-05-28 21:48:26 +02:00
|
|
|
|
|
|
|
There are some special settings to make life with only a Telnet
|
2012-02-12 03:53:01 +01:00
|
|
|
|
|
|
|
CONFIG_RAMLOG=y - Enable the RAM-based logging feature.
|
|
|
|
CONFIG_RAMLOG_CONSOLE=y - Use the RAM logger as the default console.
|
|
|
|
This means that any console output from non-Telnet threads will
|
|
|
|
go into the circular buffer in RAM.
|
|
|
|
CONFIG_RAMLOG_SYSLOG - This enables the RAM-based logger as the
|
|
|
|
system logger. This means that (1) in addition to the console
|
|
|
|
output from other tasks, ALL of the debug output will also to
|
|
|
|
to the circular buffer in RAM, and (2) NSH will now support a
|
|
|
|
command called 'dmesg' that can be used to dump the RAM log.
|
|
|
|
|
|
|
|
There are a few other configuration differences as necessary to support
|
|
|
|
this different device configuration. Just the do the 'diff' if you are
|
|
|
|
curious.

NOTES:

2014-03-01 14:44:55 +01:00
|
|
|
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
|
|
change this configurations using that tool, you should:
|
|
|
|
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
2015-06-28 16:08:57 +02:00
|
|
|
see additional README.txt files in the NuttX tools repository.
|
2014-03-01 14:44:55 +01:00
|
|
|
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
|
|
reconfiguration process.
|
|
|
|
|
|
|
|
2. See the notes for the nsh configuration. Most also apply to the nsh2
|
2012-04-17 00:43:40 +02:00
|
|
|
configuration. Like the nsh configuration, this configuration can
|
|
|
|
be modified to support a variety of additional tests.
|
2012-02-03 00:14:54 +01:00
|
|
|
|
2014-03-01 14:44:55 +01:00
|
|
|
3. RS-232 is disabled, but Telnet is still available for use as a console.
|
2012-02-21 20:16:41 +01:00
|
|
|
Since RS-232 and SDIO use the same pins (one controlled by JP22), RS232
|
|
|
|
and SDIO cannot be used concurrently.
|
2012-02-03 00:14:54 +01:00
|
|
|
|
2014-03-01 14:44:55 +01:00
|
|
|
4. This configuration requires that jumper JP22 be set to enable SDIO
|
2012-07-12 18:11:43 +02:00
|
|
|
operation. To enable MicroSD Card, which shares same I/Os with RS-232,
|
|
|
|
JP22 is not fitted.
|
2012-02-03 00:14:54 +01:00
|
|
|
|
2014-03-01 14:44:55 +01:00
|
|
|
5. In order to use SDIO without overruns, DMA must be used. The STM32 F4
|
2012-02-21 20:16:41 +01:00
|
|
|
has 192Kb of SRAM in two banks: 112Kb of "system" SRAM located at
|
2012-04-07 22:54:45 +02:00
|
|
|
0x2000:0000 and 64Kb of "CCM" SRAM located at 0x1000:0000. It appears
|
|
|
|
that you cannot perform DMA from CCM SRAM. The work around that I have now
|
|
|
|
is simply to omit the 64Kb of CCM SRAM from the heap so that all memory is
|
2012-05-28 21:48:26 +02:00
|
|
|
allocated from System SRAM. This is done by setting:
|
|
|
|
|
2012-02-21 20:16:41 +01:00
|
|
|
CONFIG_MM_REGIONS=1
|
|
|
|
|
|
|
|
Then DMA works fine. The downside is, of course, is that we lose 64Kb
|
|
|
|
of precious SRAM.
|
|
|
|
|
2014-03-01 14:44:55 +01:00
|
|
|
6. Another SDIO/DMA issue. This one is probably a software bug. This is
|
2012-02-21 23:00:28 +01:00
|
|
|
the bug as stated in the TODO list:
|
|
|
|
|
|
|
|
"If you use a large I/O buffer to access the file system, then the
|
|
|
|
MMCSD driver will perform multiple block SD transfers. With DMA
|
|
|
|
ON, this seems to result in CRC errors detected by the hardware
|
2012-02-27 20:50:35 +01:00
|
|
|
during the transfer. Workaround: CONFIG_MMCSD_MULTIBLOCK_DISABLE=y"
|
2012-02-21 23:00:28 +01:00
|
|
|
|
2012-02-27 20:50:35 +01:00
|
|
|
For this reason, CONFIG_MMCSD_MULTIBLOCK_DISABLE=y appears in the defconfig
|
2012-02-21 23:00:28 +01:00
|
|
|
file.
|
|
|
|
|
2014-03-01 14:44:55 +01:00
|
|
|
7. Another DMA-related concern. I see this statement in the reference
|
2012-02-21 23:00:28 +01:00
|
|
|
manual: "The burst configuration has to be selected in order to respect
|
|
|
|
the AHB protocol, where bursts must not cross the 1 KB address boundary
|
|
|
|
because the minimum address space that can be allocated to a single slave
|
|
|
|
is 1 KB. This means that the 1 KB address boundary should not be crossed
|
|
|
|
by a burst block transfer, otherwise an AHB error would be generated,
|
|
|
|
that is not reported by the DMA registers."
|
|
|
|
|
|
|
|
There is nothing in the DMA driver to prevent this now.

----------
|

|
This is yet another NSH configuration. This NSH configuration differs
|
2014-09-20 23:01:50 +02:00
|
|
|
from the others, however, in that it uses the NxTerm driver to host
|
2012-04-27 18:20:32 +02:00
|
|
|
the NSH shell.

A simple test of the Telnet daemon(see apps/netutils/README.txt,

apps/examples/README.txt, and apps/examples/telnetd). This is

the same daemon that is used in the nsh configuration so if you

use NSH, then you don't care about this. This test is good for
|
|
|
|
testing the Telnet daemon only because it works in a simpler

|
environment than does the nsh configuration.
