Development Environment
=======================
The Development environments for the STM32F429I-DISCO board are identical
to the environments for other STM32F boards. For full details on the
environment options and setup, see the README.txt file in the
config/stm32f4discovery directory.

config/stm32f4discovery directory.
Setup and Programming Flash
===========================
I use a USB cable to power and program it. And I use a USB/Serial
connected to pins PA9 and PA10 for the serial console.
FLASH may be programmed:
- Via USB using STM32 ST-Link Utility
- Via USB using OpenOCD. This command may be used to flash the
firmware using OpenOCD:
$ sudo openocd -f interface/stlink-v2.cfg -f target/stm32f4x.cfg -c init -c "reset halt" -c "flash write_image erase nuttx.bin 0x08000000"
- Via JTAG/SWD connected to the SWD connector CN2.

1. This configuration assumes an SST25VF064C 8Mbyte SPI FLASH is
connected to SPI4 on the following Discovery board Pins:
SCK: Port PE2 Board Connector P1, Pin 15
MOSI: Port PE6 Board Connector P1, Pin 11

the system logging device. To use this UART, you must add an
external RS-232 line driver to the UART1 pins of the DISCO board
on PA9 and PA10 of connector P1.

nuttx-code/NxWidgets/UnitTests/README.txt
Here is the quick summary of the build steps (Assuming that all of
the required packages are available in a directory ~/nuttx-code):
1. Install the nxwm configuration
$ cd ~/nuttx-code/nuttx/tools
$ ./configure.sh stm32f429i-disco/nxwm
2. Make the build context (only)
$ cd ..
$ . ./setenv.sh
$ make context
...
3. Install the nxwm unit test
$ cd ~/nuttx-code/NxWidgets
$ tools/install.sh ~/nuttx-code/apps nxwm
Creating symbolic link
- To ~/nuttx-code/NxWidgets/UnitTests/nxwm
- At ~/nuttx-code/apps/external
4. Build the NxWidgets library
$ cd ~/nuttx-code/NxWidgets/libnxwidgets
$ make TOPDIR=~/nuttx-code/nuttx
...
5. Build the NxWM library
$ cd ~/nuttx-code/NxWidgets/nxwm
$ make TOPDIR=~/nuttx-code/nuttx
...
6. Built NuttX with the installed unit test as the application
$ cd ~/nuttx-code/nuttx
$ make
