Hi people,
first i would like to apologize for any rudeness or agressive looking post. I am french, and although i can write in English, i still have problems with the way it should be used :lol:
First a little intro. I am a software developer, and usually work on preconfigured toolchains. Most of the time i work on airplane embedded systems, but i happen to also work on standard stuff sometimes. The last time it happened, i worked on setting the str935 board linux bsp (forgive me if that was not a good work, i did not know anything about arm at this time :o )
the thing is that i liked it quite. And i also happen to have hobbies such as racing. I kind of needed some electronic gizzmos to monitor the car sensors and sound alarms (and also to remove the speed limiter), but this kind of components is really expensive (around 1K£ for a complete system with 10Hz GPS tracking) . So i thought “hey, let’s build one myself!”
So i searched for a convenient development board. Olimex one, with the prototype area caught my eyes, but i ended up buying something with hugely higher value for the money (or so i thought). Well, the board itself is nice and packed with features but … it comes with chinese docs. The only valuable things in there are some code snippets and the electric schemes.
anyway, for around 50£, i got an stm32f103RBT6 based board with a VGA tft touchscreen, usb, serial, spi, adc and MMC slot. Did i mention it was cheap ? And compact too. You can find it on ebay by looking for “stm32 2.8 tft” . I can paste the link here but i guess that for a first post, it would be considered as spam :mrgreen: if people want the link i will post it though. I found another guy who sells the same board, but with a J-link module, for 100$ too.
Now that you basically know what i want and can do, lets go to the facts.
I followed the instruction from stf12developer to install a developement system. Tried on linux (and failed), tried on windows XP and somewhat succeeded after numerous attemps.
I am now using eclipse (i always hated it, but hey, it works), code sourcery compilers and openOCD v0.10 (and v0.20) .
i installed the amontec key tiny using their drivers, and from what i have read around it might be the source of the problem, but anyway …
The thing is that i cant make the key work with openOCD. I tried both 0.10 and 0.20 version and i always end up with errors. here is the last error log (v0.20):

i tried adapting the config files to my setup, but i cant see what is wrong with them. Or is something wrong with me ?
here is the command used : openocd.exe -f jtagkey.cfg -f stm32_mdBZ.cfg -fstm32_program_eclipse.cfg
here are my config files :

can anyone see what is wrong here ? I am getting desperate, i started this a month ago and i still cant have jtag working
