Connect to custom board STM32L053 - STLINK-V2 - SWD
Hi Andrey,
you shoudl try to dig in .cfg files that are in the AC6 gcc eclipse plugin. And notably in .\eclipse\plugins\fr.ac6.mcu.debug_1.3.0.201507241045\resources\openocd\scripts\target\stm32F4.cfg file.
Some reset / connection options are set in it (line 86)
You should check it’s still what you want.
Hope that help,
Regards,
Sylvain
