[OpenOCD-devel] issues programming stm32f4 with stlink v2

[Angelo D. <ang...@gm...>]

Dear all,

i am trying to program stm32f405 with a cheap stlink-V2, without success.
I attach the log, maybe someone can help me.

May be the fact i didn't connected NJTRST pin to the programmer 
(should'n be mandatory) ?

many thanks
