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

What if you use the Windows ST-LINK utilities?

Connect in SWD mode?

For support you may get help quicker if you post to the OpenOCD mailing list.

As a guess I would say that you are not erasing the flash first. Depending on what your are trying todo a better cmd may be to use write_image. flash write_image erase stm32f4x.bin 0 Also use the generated elf rather than generating a binary. Newer versions of OpenOCD have a programming helper script - see http://openocd.sourceforge.net/doc/html/Flash-Programming.html#Flash-Programming Spen
