stm32x405, can't program through stlink v2
Posted on March 16, 2014 at 22:54
Dear all,
after some issues using a programmer as parport interface, i am trying to program stm32f405 with a cheap stlink-V2, but still without success. I attach the openocd log, maybe someone can help me.

Polling again in 6300m May be the fact i didn't connected NJTRST pin to the programmer (should'n be mandatory) ? Every help si appreciated. many thanks angelo
