This directory contains a simple RIDE7 project used to bring up the
|
||||
STM3210E-EVAL board. This project includes only the STM32 boot-up
|
||||
code under arch/arm/src and configs/stm3210e-eval/src plus as little
|
||||
additional environmental support as necessary.
|
||||
|
||||
bigfatstub.c

The NuttX OS is not included in this project. This file contains
|
||||
stubs for all of the NuttX entry points and this replaces NuttX
|
||||
|
||||
Make.defs, defconfig, setenv.h
|
||||
|
||||
The first step to using this RIDE project is to build a compatible
|
||||
cygwin project. This will set up of the directories and produce
|
||||
all of the necessary autogenerated files.

stm32-ld.sh
|

|

This is a shell script that will use the RIDE7 tools to relink the
|

NuttX binaries. Useful because RIDE7 does not provide much linker
|
||||
output to see what is going on.
