PROBLEM: reconnecting a Nucleo-F767ZI with the cut ST-Link.

I'm a STM32 beginner and i'm trying to reconnect a Nucleo-F767ZI with the cut ST-Link. I'm working with ChibiOs and i get the error: target voltage may be too low for reliable debugging. But i get some kind of communication (LD1 shows red and green)

I'm using the SWD Port on the ST-Link and an external 5V powersupply (E5V) and I connected the SRT-Link like this: SWCLK to CN11 pin 15, SWDIO to CN11 pin 13, NRST to CN11 pin 14, VDD_Target to CN11 pin 5. I also detached the Jumpers CN4 on the ST-Link and got the Jumper JP3 to E5V.

Clearly too high... Not sure what happens, I just hope this is not what actually going to the STM32. Please check.

Please use latest ST-Link FW version. I sse that you reverted to V2J29M18, was V2J38M27 in your previous screenshot.

Maybe it'll solve the issue.

I updated the ST-Link FW to V2.J38.M27 now and i still get 6V...
