======
|
|
|
|
The Olimex STM32-H407 configuration is based on
|
|
stm32Fdiscovery and Olimex STM32-H405.
|
|
|
|
The H407 was programmed with ST-LINK/V2 from both Win8.1 and Ubuntu 14.04
|
|
This release provides baseline for H407 12MHZ clock in include/board.h
|
|
|
|
nsh - Only basic shell response tested on USART2
|
|
nsh_uext - Basic shell response tested on USART6 (UEXT)
|
|
|
|
Development Environment
|
|
=======================
|
|
|
|
Either Linux or Cygwin on Windows can be used for the development environment.
|
|
The source has been built only using the GNU toolchain (see below). Other
|
|
toolchains will likely cause problems.
|
|
|
|
LEDs
|
|
====
|
|
|
|
The H407 board has 1 Status LED;
|
|
|
|
SDCard
|
|
======
|
|
|
|
Expects to be plugged in else hangs. TODO: Shouldn't hang.
|
|
SDIO 4bit with pulls/downs on pins. Doesn't have a SD card detect pin.
|
|
|
|
UARTs
|
|
=====
|
|
|
|
On the H407 board, ?? all uarts are available for pin mappings
|
|
USART2 can be used for nsh console like on Discovery board,
|
|
or you can use USART6 exposed via UEXT connector.
|
|
|
|
Olimex offers MOD-RS232 voltage level convertor for the UEXT so it can be
|
|
attached to computer serial port.
