This is the smallest-possible example program using libopenstm32.
|
||||
|
||||
It's intended for the ST STM32-based Olimex STM32-H103 eval board (see
|
||||
http://olimex.com/dev/stm32-h103.html for details). It should blink
|
||||
the LED on the board.
|
||||
|
||||
|
||||
Building
|
||||
--------
|
||||
|
||||
$ make
|
||||
|
||||
Running 'make' on the top-level libopenstm32 directory will automatically
|
||||
also build this example. Or you can build the library "manually" and
|
||||
then run 'make' in this directory.
|
||||
|
||||
You may want to override the toolchain (e.g., arm-elf or arm-none-eabi):
|
||||
|
||||
$ PREFIX=arm-none-eabi make
|
||||
|
||||
For a more verbose build you can use
|
||||
|
||||
$ make V=1
|
||||
|
||||
|
||||
Flashing
|
||||
--------
|
||||
|
||||
You can flash the generated code on the STM32-H103 board using OpenOCD:
|
||||
|
||||
$ make flash
|
||||
|
||||
Or you can do the same manually via:
|
||||
|
||||
$ openocd -f interface/jtagkey-tiny.cfg -f board/olimex_stm32_h103.cfg
|
||||
$ telnet localhost 4444
|
||||
> reset halt
|
||||
> flash write_image erase fancyblink.hex
|
||||
> reset
|
||||
|
||||
Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using, and/or
|
||||
replace "olimex_stm32_h103.cfg" with your respective board config file.

README

|

|

This example program sends some characters on USART3 on the ST STM32-based
|
||||
Olimex STM32-H103 eval board (see http://olimex.com/dev/stm32-h103.html
|
||||
for details).
|
||||
|
||||
The terminal settings for the receiving device/PC are 38400 8n1.
|
||||
|
||||
|
||||
Building
|
||||
--------
|
||||
|
||||
$ make
|
||||
|
||||
Running 'make' on the top-level libopenstm32 directory will automatically
|
||||
also build this example. Or you can build the library "manually" and
|
||||
then run 'make' in this directory.
|
||||
|
||||
You may want to override the toolchain (e.g., arm-elf or arm-none-eabi):
|
||||
|
||||
$ PREFIX=arm-none-eabi make
|
||||
|
||||
For a more verbose build you can use
|
||||
|
||||
$ make V=1
|
||||
|
||||
|
||||
Flashing
|
||||
--------
|
||||
|
||||
You can flash the generated code on the STM32-H103 board using OpenOCD:
|
||||
|
||||
$ make flash
|
||||
|
||||
Or you can do the same manually via:
|
||||
|
||||
$ openocd -f interface/jtagkey-tiny.cfg -f board/olimex_stm32_h103.cfg
|
||||
$ telnet localhost 4444
|
||||
> reset halt
|
||||
> flash write_image erase usart.hex
|
||||
> reset
|
||||
|
||||
Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using, and/or
|
||||
replace "olimex_stm32_h103.cfg" with your respective board config file.
