St link¶

Programming the stm32f4 discovery board.

Getting the example code¶

Change into your home directory and checkout the ppci source code:

$ cd ~
$ mkdir HG
$ cd HG
$ hg clone https://bitbucket.org/windel/ppci

If everything went well, you now have the latest version of ppci checked out.

Building¶

Compiling the stm32f4xx example project using the compiler toolchain:

$ cd ~/HG/ppci/test/data/stm32f4xx
$ zcc.py build

  2014-08-15 12:40:15,711|INFO|taskrunner|Target all
  2014-08-15 12:40:15,711|INFO|taskrunner|Done!
$ ls -latr
  burn2.hex

Flashing¶

First inspect the hexfile you want to flash with the hexutil program:

$ hexutil.py info ~/HG/ppci/test/data/stm32f4xx/burn2.hex
  Hexfile containing 408 bytes
  Region at 0x08000000 of 408 bytes

To flash an application using the st-link V2 debugger, use the st-flash program:

$ st-flash.py hexwrite burn2.hex
  flashing Region at 0x08000000 of 408 bytes
