-
-This is a small 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
- > init
- > reset halt
- > flash write_image erase blink.bin 0x08000000
- > resume 0x08000000
-
-Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using.
