Getting STM32 STlink V2 running with OpenSTm32 IDE and OPENOCD

Some time ago I needed bit more power that the regular Arduino is able to provide. Therefore I thought, lets brush up my ARM skills.

So I desired to make some hefty investments in ARM, here is what i got:

  • STM32F103CTB dev board, $4,88
  • ST LINK-v2 (clone), $4,08

STM32f103C8T6ST LINk -v2

This was a major sad back, not taking in consideration the poor EUR -> $ ratio 🙂

NO but searilously cheap, just the way any duch-guy likes it 😛

 

Then it is time to fire up the IDE, many to choose from, I chose: OpenSTM32 (which is basically a pre-setup Eclipse environment).

Compiling a sample project when without a glitch, but uploading… not so much..

OpenOCD just kept complaining:

adapter speed: 1000 kHz
adapter_nsrst_delay: 100
none separate
Info : Unable to match requested speed 1000 kHz, using 950 kHz
Info : Unable to match requested speed 1000 kHz, using 950 kHz
Info : clock speed 950 kHz
Error: open failed
in procedure 'init'
in procedure 'ocd_bouncer'

After a hefty bit of googling I finalymanaged to get it uploading my code and stepping thru it:

Add the lines:

monitor reset
monitor halt
monitor flash protect 0 0 11 off

to the Debug Configuration -> Startup tab:

startup-addition eclipse OpenSTM32

It know purrs like a kitten
