Hopefully someone can help.
Below I get some connection and identification proceeding, but it fails at the end with
"Cannot identify target as an STM32G0/G4/L4/L4+/L5/U5/WB/WL family device."
UPDATE!: I copied the openocd.exe from my installation of stm32CubeIde and it works.
Although there is a STM32U5x.cfg added to the latest openocd on the official build, there must be something missing from the binary, which I can fix by using the STM32CubeIde openocd.exe
