OpenSDAv2
|
|
|
|
=========
|
|
|
|
|
|
|
|
The FRDM-K64F platform features OpenSDAv2, the Freescale open-source
|
|
|
|
hardware embedded serial and debug adapter running an open-source
|
|
|
|
bootloader. This circuit offers several options for serial communication,
|
|
|
|
flash programming, and run-control debugging. OpenSDAv2 is an mbed
|
|
|
|
HDK-compatible debug interface preloaded with the open-source CMSIS-DAP
|
|
|
|
Interface firmware (mbed interface) for rapid prototyping and product
|
|
|
|
development.

Serial Console
|
|
|
|
==============
|
|
|
|
|
2016-07-02 23:27:12 +02:00
|
|
|
USB VCOM Console
|
|
|
|
----------------
|
2016-07-02 21:58:29 +02:00
|
|
|
The primary serial port interface signals are PTB16 UART0_RX and PTB17
|
2016-07-02 23:27:12 +02:00
|
|
|
UART0_TX. These signals are connected to the OpenSDAv2 VCOM circuit.
|
|
|
|
|
|
|
|
Serial Shield Console
|
|
|
|
---------------------
|
|
|
|
An alternative serial port might use a standard serial shield mounted
|
|
|
|
on the Freedom Board. In this case, Arduino pin D1 provides UART TX and
|
2020-02-23 09:50:23 +01:00
|
|
|
pin D0 provides UART RX.
|
2016-07-02 23:27:12 +02:00
|
|
|
|
|
|
|
The I/O headers on the FRDM-K64F board are arranged to enable
|
|
|
|
compatibility with Arduino shield. The outer rows of pins (even numbered
|
|
|
|
pins) on the headers, share the same mechanical spacing and placement with
|
|
|
|
the I/O headers on the Arduino Revision 3 (R3) standard.
|
|
|
|
|
|
|
|
The Arduino D0 and D1 pins then correspond to pins 2 and 4 on the J1 I/O
|
|
|
|
connector:

|

|
|

UART RX, Arduino D0 pin Pin 2, PTC16, UART3_RX
|
|
|
|
|
|
|
|
Default Serial Console
|
|
|
|
----------------------
|
|
|
|
By default, these configuration are setup to use the Serial Console on
|
|
|
|
UART3. That, however, is easily reconfigured.

|
If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board the
|
|
|
|
Freedom KL25Z. Usage of these LEDs is defined in include/board.h and
|
|
|
|

Buttons
|
|
|
|
-------
|
|
|
|
Two push buttons, SW2 and SW3, are available on FRDM-K64F board, where
|
|
|
|
SW2 is connected to PTC6 and SW3 is connected to PTA4. Besides the
|
|
|
|
general purpose input/output functions, SW2 and SW3 can be low-power
|
|
|
|
wake up signal. Also, only SW3 can be a non-maskable interrupt.

Using the network with NSH
|
|
|
|
--------------------------
|
|
|
|
|
|
|
|
So what can you do with this networking support? First you see that
|
|
|
|
NSH has several new network related commands:
|
|
|
|
|
|
|
|
ifconfig, ifdown, ifup: Commands to help manage your network
|
|
|
|
get and put: TFTP file transfers
|
|
|
|
wget: HTML file transfers
|
|
|
|
ping: Check for access to peers on the network
|
|
|
|
Telnet console: You can access the NSH remotely via telnet.
|
|
|
|
|
|
|
|
You can also enable other add on features like full FTP or a Web
|
|
|
|
Server or XML RPC and others. There are also other features that
|
|
|
|
you can enable like DHCP client (or server) or network name
|
|
|
|
resolution.
|
|
|
|
|
2017-02-08 03:09:22 +01:00
|
|
|
By default, the IP address of the FRDM-K64F will be 10.0.0.2 and
|
2016-07-13 00:50:27 +02:00
|
|
|
it will assume that your host is the gateway and has the IP address
|
|
|
|
10.0.0.1.
|
|
|
|
|
|
|
|
nsh> ifconfig
|
|
|
|
eth0 HWaddr 00:e0:de:ad:be:ef at UP
|
|
|
|
IPaddr:10.0.0.2 DRaddr:10.0.0.1 Mask:255.255.255.0
|
|
|
|
|
|
|
|
You can use ping to test for connectivity to the host (Careful,
|
|
|
|
Window firewalls usually block ping-related ICMP traffic). On the
|
|
|
|
target side, you can:
|
|
|
|
|
|
|
|
nsh> ping 10.0.0.1
|
|
|
|

|
|
|

|
|
|
|
10 packets transmitted, 10 received, 0% packet loss, time 10100 ms
|
|
|
|
|
|
|
|
NOTE: In this configuration is is normal to have packet loss > 0%
|
|
|
|
the first time you ping due to the default handling of the ARP
|
|
|
|
table.
|
|
|
|
|
2017-02-08 03:09:22 +01:00
|
|
|
On the host side, you should also be able to ping the FRDM-K64F:
|

|
NOTE: If you enable this networking as described above, you will
|
|
|
|
experience a delay on booting NSH. That is because the start-up logic
|
|
|
|
waits for the network connection to be established before starting
|
|
|
|
NuttX. In a real application, you would probably want to do the
|
|
|
|
network bringup on a separate thread so that access to the NSH prompt
|
|
|
|
is not delayed.
|
|
|
|
|
|
|
|
This delay will be especially long if the board is not connected to
|
|
|
|
a network. On the order of minutes! You will probably think that
|
|
|
|
NuttX has crashed! And then, when it finally does come up after
|
|
|
|
numerous timeouts and retries, the network will not be available --
|
|
|
|
even if the network cable is plugged in later.
|
|
|
|
|
|
|
|
The long delays can be eliminated by using a separate the network
|
|
|
|
initialization thread discussed below. Recovering after the network
|
|
|
|
becomes available requires the network monitor feature, also discussed
|
|
|
|
below.
|
|
|
|
|
|
|
|
Network Initialization Thread
|
|
|
|
-----------------------------
|
|
|
|
There is a configuration option enabled by CONFIG_NSH_NETINIT_THREAD
|
|
|
|
that will do the NSH network bring-up asynchronously in parallel on
|
|
|
|
a separate thread. This eliminates the (visible) networking delay
|
|
|
|
altogether. This current implementation, however, has some limitations:
|
|
|
|
|
|
|
|
- If no network is connected, the network bring-up will fail and
|
|
|
|
the network initialization thread will simply exit. There are no
|
|
|
|
retries and no mechanism to know if the network initialization was
|
|
|
|
successful (it could perform a network Ioctl to see if the link is
|
|
|
|
up and it now, keep trying, but it does not do that now).
|
|
|
|
|
|
|
|
- Furthermore, there is currently no support for detecting loss of
|
|
|
|
network connection and recovery of the connection (similarly, this
|
|
|
|
thread could poll periodically for network status, but does not).
|
|
|
|
|
|
|
|
Both of these shortcomings could be eliminated by enabling the network
|
|
|
|
monitor:
|
|
|
|
|
|
|
|
Network Monitor
|
|
|
|
---------------
|
|
|
|
By default the network initialization thread will bring-up the network
|
|
|
|
then exit, freeing all of the resources that it required. This is a
|
|
|
|
good behavior for systems with limited memory.
|
|
|
|
|
|
|
|
If the CONFIG_NSH_NETINIT_MONITOR option is selected, however, then the
|
|
|
|
network initialization thread will persist forever; it will monitor the
|
|
|
|
network status. In the event that the network goes down (for example, if
|
|
|
|
a cable is removed), then the thread will monitor the link status and
|
|
|
|
attempt to bring the network back up. In this case the resources
|
|
|
|
required for network initialization are never released.
|
|
|
|
|
|
|
|
Pre-requisites:
|
|
|
|
|
|
|
|
- CONFIG_NSH_NETINIT_THREAD as described above.
|
|
|
|
|
|
|
|
- The K64F EMAC block does not support PHY interrupts. The KSZ8081
|
|
|
|
PHY interrupt line is brought to a jumper block and it should be
|
|
|
|
possible to connect that some some interrupt port pin. You would
|
|
|
|
need to provide some custom logic in the Freedcom K64F
|
|
|
|
configuration to set up that PHY interrupt.
|
|
|
|
|
2020-02-22 19:31:14 +01:00
|
|
|
- In addition to the PHY interrupt, the Network Monitor also requires the
|
2016-07-13 00:50:27 +02:00
|
|
|
following setting:
|
|
|
|
|
|
|
|
CONFIG_NETDEV_PHY_IOCTL. Enable PHY IOCTL commands in the Ethernet
|
|
|
|
device driver. Special IOCTL commands must be provided by the Ethernet
|
|
|
|
driver to support certain PHY operations that will be needed for link
|
|
|
|
management. There operations are not complex and are implemented for
|
|
|
|
the Atmel SAMA5 family.
|
|
|
|
|
|
|
|
CONFIG_ARCH_PHY_INTERRUPT. This is not a user selectable option.
|
|
|
|
Rather, it is set when you select a board that supports PHY
|
|
|
|
interrupts. For the K64F, like most other architectures, the PHY
|
|
|
|
interrupt must be provided via some board-specific GPIO. In any
|
|
|
|
event, the board-specific logic must provide support for the PHY
|
|
|
|
interrupt. To do this, the board logic must do two things: (1) It
|
|
|
|
must provide the function arch_phy_irq() as described and prototyped
|
|
|
|
in the nuttx/include/nuttx/arch.h, and (2) it must select
|
|
|
|
CONFIG_ARCH_PHY_INTERRUPT in the board configuration file to
|
|
|
|
advertise that it supports arch_phy_irq().
|
|
|
|
|
2019-04-29 22:52:05 +02:00
|
|
|
One other thing: UDP support is required (CONFIG_NET_UDP).
|
2016-07-13 00:50:27 +02:00
|
|
|
|
|
|
|
Given those prerequisites, the network monitor can be selected with these
|
|
|
|
additional settings.

A micro Secure Digital (SD) card slot is available on the FRDM-K64F connected to
|
|
|
|
the SD Host Controller (SDHC) signals of the MCU. This slot will accept micro
|
|
|
|
format SD memory cards. The SD card detect pin (PTE6) is an open switch that

2016-07-13 17:23:57 +02:00
|
|
|
|
|
|
|
Using the SD card
|
|
|
|
-----------------
|
|
|
|
|
|
|
|
1. After booting, the SDHC device will appear as /dev/mmcsd0.
|
|
|
|
2. If you try mounting an SD card with nothing in the slot, the mount will
|
|
|
|
fail:
|
|
|
|
|
|
|
|
nsh> mount -t vfat /dev/mmcsd0 /mnt/sd0
|
|
|
|
nsh: mount: mount failed: 19
|
|
|
|
|
|
|
|
NSH can be configured to provide errors as strings instead of
|
|
|
|
numbers. But in this case, only the error number is reported. The
|
|
|
|
error numbers can be found in nuttx/include/errno.h:
|
|
|
|
|
|
|
|
#define ENODEV 19
|
|
|
|
#define ENODEV_STR "No such device"
|
|
|
|
|
|
|
|
So the mount command is saying that there is no device or, more
|
|
|
|
correctly, that there is no card in the SD card slot.
|
|
|
|
|
|
|
|
3. Insert the SD card. Then the mount should succeed.
|
|
|
|
|
|
|
|
nsh> mount -t vfat /dev/mmcsd0 /mnt/sd0
|
|
|
|
nsh> ls /mnt/sd1
|
|
|
|
/mnt/sd1:
|
|
|
|
atest.txt
|
|
|
|
nsh> cat /mnt/sd1/atest.txt
|
|
|
|
This is a test
|
|
|
|
|
|
|
|
NOTE: See the next section entitled "Auto-Mounter" for another way
|
|
|
|
to mount your SD card.
|
|
|
|
|
|
|
|
4. Before removing the card, you must umount the file system. This is
|
|
|
|
equivalent to "ejecting" or "safely removing" the card on Windows: It
|
|
|
|
flushes any cached data to an SD card and makes the SD card unavailable
|
|
|
|
to the applications.
|
|
|
|
|
|
|
|
nsh> umount -t /mnt/sd0
|
|
|
|
|
|
|
|
It is now safe to remove the card. NuttX provides into callbacks
|
|
|
|
that can be used by an application to automatically unmount the
|
|
|
|
volume when it is removed. But those callbacks are not used in
|
|
|
|
these configurations.
|
|
|
|
|
|
|
|
Auto-Mounter
|
|
|
|
------------
|
|
|
|
NuttX implements an auto-mounter than can make working with SD cards
|
|
|
|
easier. With the auto-mounter, the file system will be automatically
|
|
|
|
mounted when the SD card is inserted into the SDHC slot and automatically
|
|
|
|
unmounted when the SD card is removed.
|
|
|
|
|
|
|
|
Here is a sample configuration for the auto-mounter:
|
|
|
|
|
|
|
|
File System Configuration
|
|
|
|
CONFIG_FS_AUTOMOUNTER=y
|
|
|
|

|
|
|
Board-Specific Options

|
|
|
CONFIG_FRDMK64F_SDHC_AUTOMOUNT=y
|
|
|
|
CONFIG_FRDMK64F_SDHC_AUTOMOUNT_FSTYPE="vfat"
|
|
|
|
CONFIG_FRDMK64F_SDHC_AUTOMOUNT_BLKDEV="/dev/mmcsd0"
|
|
|
|
CONFIG_FRDMK64F_SDHC_AUTOMOUNT_MOUNTPOINT="/mnt/sdcard"
|
|
|
|
CONFIG_FRDMK64F_SDHC_AUTOMOUNT_DDELAY=1000
|
|
|
|
CONFIG_FRDMK64F_SDHC_AUTOMOUNT_UDELAY=2000
|
|
|
|
|
|
|
|
WARNING: SD cards should never be removed without first unmounting
|
|
|
|
them. This is to avoid data and possible corruption of the file
|
|
|
|
system. Certainly this is the case if you are writing to the SD card
|
|
|
|
at the time of the removal. If you use the SD card for read-only access,
|
|
|
|
however, then I cannot think of any reason why removing the card without
|
|
|
|
mounting would be harmful.

The NuttX make system supports several GNU-based toolchains under Linux,
|
2018-01-24 15:52:40 +01:00
|
|
|
Cygwin under Windows, and Windows native. To select a toolchain:

|
|
|
|
2016-07-02 15:56:43 +02:00
|
|
|
1. Use 'make menuconfig' and select the toolchain that you are using
|
|
|
|
under the System Type menu.
|
|
|
|
2. The default toolchain is the NuttX buildroot under Linux or Cygwin:

|
|
|
You may also have to modify the PATH environment variable if your make cannot
|
|
|
|
find the tools.

it installs OK on Windows 7.

4. Support for NSH built-in applications is enabled, but no built-in

applications have been configured in.

5. An SDHC driver is enabled in this configuration but does not yet work.

The basic problem seems to be that it does not sense the presence of
|
|
|
|
the SD card on PTE6. No interrupts are generated when the SD card is
|
|
|
|
inserted or removed. You might want to disable SDHC and MMC/SD if
|
|
|
|
you are using this configuration. Refer to the configuration
|
|
|
|
settings listed above under "SD Card Support".

2016-07-11: Received hardware today and the board came up on the very
|
|
|
|
first try. That does not happen often. At this point, the very basic
|
2016-07-14 18:10:37 +02:00
|
|
|
NSH configuration is working and LEDs are working.
|
|
|
|
|
|
|
|
The only odd behavior that I see is that pressing SW3 causes an NMI
|
|
|
|
interrupt (followed by a crash):
|
|
|
|
|
|
|
|
kinetis_nmi: PANIC!!! NMI received
|
|
|
|
|
|
|
|
I don't yet understand why this is.

configuration. The network is basically functional. More testing is
|
|
|
|
needed, but I have not seen any obvious network failures.

In testing, I notice a strange thing. If I run at full optimization the
|
|
|
|
code runs (albeit with bugs-to-be-solved). But with no optimization or
|
|
|
|
even at -O1, the system fails to boot. This seems to be related to the
|
|
|
|
watchdog timer.

2016-07-13: Add SD automounter logic; broke out SDHC logic into a separate
|
|
|
|
file. The nsh configuration now has SDHC enabled be default. Does not
|
2016-07-13 22:26:18 +02:00

|
|
yet work. The basic problem seems to be that it does not sense the
|
|
|
|
presence of the SD card on PTE6. No interrupts are generated when the
|
|
|
|
SD card is inserted or removed. You might want to disable SDHC and
|
2016-07-14 18:10:37 +02:00
|
|
|
MMC/SD if you are using this configuration.
|
|
|
|
|
|
|
|
The nsh configuration now builds successfully with USB device enabled.
|
|
|
|
USB device, however, has not yet been tested. I have not yet looked
|
|
|
|
into 48MHz clocking requirements.

2017-02-10: These have been numerous SDHC fixes submitted by Marc Rechte'.
|
|
|
|
These may or may not have fixed the SDHC issues mentioned about. You
|
|
|
|
would have to retest to verify the SDHC functionality.
