AC6 + ST-Link V2 + SWD programming
Custom board
STM32F407 MCU
The programming, debugging and everything works using Keil and Atollic systems, with STM utilities etc.
I'll check if I can get the printout of the whole failing procedure in coming days if that helps. There should be a easy way to configure the system to work without Reset wire connection (as the whole programming/debugging interface is built to work without it).
