I have a STM32091C-EVAL board, and I'm trying to get console output on the STLink-2.1 debug console interface throught USART5, but I have no output by the STLink.
- I have updated the STLink firmware to the latest 2.29.18, no effect
- I took the USART5 signals from the CN6 header, I have correct console output
- I soldered an header on the CN17 header, right before the stlink, after the U17, nothing, output line is allways at 0
I suspect the level shifter to be faulty, because the voltages on the level shifter pins are OK.
Anybody got the same issue ? is it only on my board ?
