Add support for LPC40xx family chips
* Corrected a few peripheral definitions and pin functions for the LPC17xx family.
Added configuration options, chip definitions, and additional pin functions for the LPC40xx family.
Added board configurations for Embedded Artists LPC4088 Quickstart board and LPC4088 Developer's kit. These configurations are still something of a work in progress. In particular, the LCD functionality is untested.
* First pass rename in *.c and *.h files.
* Renamed LPC17XX to LPC17XX_40XX in config files
* Rplaced LPC17xx with LPC17xx/LPC40xx in .c files
* Replaced LPC17xx with LPC17xx/LPC40xx in .h files
* Updated some documentation
* Working on moving directories
* moved arch/arm/src/lpc17xx and arch/arm/include/lpc17xx to lpc17xx_40xx
* Renamed LPC17_* constants / configuration options to LPC17_40_*
* Updated chip family name defines
* Renamed some chip-specific files
* Updated references to renamed files
* Updated references to lpc17_ to lpc17_40_
* Renamed source files from lpc17_* to lpc17_40_*
* Clean up white space

|
USB Host Configuration
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The Lincoln 60 board supports a USB host interface. The hidkbd
|
|
example can be used to test this interface.
|
|
|
|
The NuttShell (NSH) lincoln60 can also be modified in order to support USB
|
|
host operations. To make these modifications, do the following:
|
|
|
|
1. First configure to build the NSH configuration from the top-level
|
|
NuttX directory:
|
|
|
|
./configure lincoln60/nsh
|
|
|
|
2. Then edit the top-level .config file to enable USB host. Make the
|
|
following changes:
|
|
|
|
CONFIG_LPC17_40_USBHOST=y
|
|
CONFIG_USBHOST=y
|
|
CONFIG_SCHED_WORKQUEUE=y
|
|
|
|
When this change is made, NSH should be extended to support USB flash
|
|
devices. When a FLASH device is inserted, you should see a device
|
|
appear in the /dev (pseudo) directory. The device name should be
|
|
like /dev/sda, /dev/sdb, etc. The USB mass storage device, is present
|
|
it can be mounted from the NSH command line like:
|
|
|
|
ls /dev
|
|
mount -t vfat /dev/sda /mnt/flash
|
|
|
|
Files on the connect USB flash device should then be accessible under
|
|
the mountpoint /mnt/flash.
|
|
|
|
Configurations
|
|
^^^^^^^^^^^^^^
|
|
|
|
Each Lincoln 60 configuration is maintained in a sub-directory and can be selected
|
|
as follow:
|
|
|
|
tools/configure.sh lincoln60/<subdir>
|
|
|
|
Where <subdir> is one of the following:
|
|
|
|
netnsh:
|
|
Configures the NuttShell (nsh) located at apps/examples/nsh. This
|
|
configuration is similar to the nsh configuration except that network
|
|
upport is enabled.
|
|
|
|
NOTES:
|
|
|
|
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
|
|
see additional README.txt files in the NuttX tools repository.
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.
|
|
|
|
2. This configuration is setup to build under Windows with Cygwin using
|
|
the CodeSourcery toolchain. That is, however, easily reconfigured.
|
|
|
|
3. This configuration uses a serial console on UART0 at 115200 8N1.
|
|
This is the serial port at the connector labelled COM1 on the
|
|
Lincoln 60.
|
|
|
|
3. This example does initializes the network, then NSH sequentially. It
|
|
does not use the NSH network monitor thread. There are two
|
|
consequences to this: 1) There will be a delay booting to the NSH
|
|
prompt while the network is brought up. This delay will normally be
|
|
small but it the network cable is unconnected, it can be very long
|
|
(you may thing that the firmware is hung). and 2) if the network is
|
|
unplugged, then re-connected. The network will not automatically be
|
|
brought back up. But you should be able to do that manually with
|
|
the NSH ifup command.
|
|
|
|
If you want better, more responsive network management, look into
|
|
the NSH network monitor thread.
|
|
|
|
nsh:
|
|
Configures the NuttShell (nsh) located at apps/examples/nsh.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|

|
|
|
|
2. This configuration is setup to build under Linux with the Nutt
|
|
buildroot toolchain. That is, however, easily reconfigured.
|
|
|
|
3. This configuration uses a serial console on UART0 at 115200 8N1.
|
|
This is the serial port at the connector labelled COM1 on the
|
|
Lincoln 60.
|
|
|
|
3. This configuration enables only the serial NSH interface. See
|
|
notes above for enabling USB host support in this configuration.
|
|
|
|
thttpd-binfs:
|
|
This builds the THTTPD web server example using the THTTPD and
|
|
the apps/examples/thttpd application. This version uses the built-in
|
|
binary format with the BINFS file system and the Union File System.
|
|
|
|
NOTES:
|
|
|
|
1. Uses the CodeSourcery EABI toolchain under Windows. But that is
|
|
easily reconfigured:
|
|
|
|
CONFIG_HOST_WINDOWS=y : Windows
|
|
CONFIG_HOST_WINDOWS_CYGWIN=y : under Cygwin
|
|
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery toolchain
|
|
|
|
STATUS:
|
|
2015-06-06: The BINFS CGI files are seems to be running, but the
|
|
output that they generate does not appear in the browser window.
|
|
I am suspecting that the redirected output is not working correctly
|
|
with the BINFS applications.
