Hello,

I try to connect to a STM32G431 Device over JTAG. I got the following error. Has someone a solution for this error?

Did you upgrade to the latest tool version like STM32CuberProgrammer 2.6?

Custom board? Nucleo32 works here as expected. What probe?

It is a self developed board. The JTAG connection works with an J-Link but not the ST-Link and STM32CubeProgrammer. Just a connection over SWD

Communication errors? You can lower the clock speed and re-check.

Firmware on the STLink recent? All STlink match JTAG ID against an internal list and reject parts they do not know(yet).

Firmware on ST Link is recent
