Olimex STM32-H103 Notes

The Olimex STM32-H103 is a ST STM32F1 based development. Pluses are the USB port, proper JTAG connector, and all I/O out on 0.1" pitch pins.

Details:

  • STM32F103RBT6 CPU
  • 128 Ki flash, 20 Ki RAM, 72 Mhz
  • Standard 20 pin JTAG connector
  • Green STAT LED on PC12
  • 8 MHz crystal

Programming

I used the Ubuntu Raring OpenOCD 0.6.0 and a Signalyzer Lite. The host is a Macbook Air running Windows with Ubuntu Raring in a VM. OpenOCD sometimes fails with a Error: unable to open ftdi device: unable to fetch product description error, but re-plugging the JTAG device fixes that.

A basic OpenOCD config file works fine:

# Olimex STM32-H103
source [find interface/signalyzer-lite.cfg]
source [find target/stm32f1x.cfg]

Programming via telnet localhost 4444 involves:

reset halt
flash probe 0
stm32f1x mass_erase 0
flash write_image blink.hex 0 ihex
reset run
