Posted on June 07, 2018 at 07:49Hi,
I have STM32469I-Eval board.
I used STM32SW4 (AC6) toolchain and built a LED toggle project and debugged it using OpenOCD.
Everything was working good.
Then i did HW modifications on it by removing CN2, CN4, R216, R217, R227, R228, R6, R15,
R80, R87, R93, R103, R107, R113, R203, R290. On JP14 used PSU, as I am using external power adaptor 5V/2A, came with the kit.
Now I am not able to connect/program the EVal board using ST-Link
utility 4.2.0.0 (with FW version: V2J30M19) and getting this error in trace log:

ST-Link get version failure
What would be the reason for this failure?
