SHCI_C2_BLE_Init Fails

[TWood.4]

I'm trying to start up CPU2 on an STM32WB55. I've looked at various examples and I seem to be doing all the right things.

SHCI_C2_BLE_Init returns 0xFF in payload[0] which corresponds to SHCI_FUS_CMD_NOT_SUPPORTED

I have FUS V1.2.0.0 installed and the Full BLE stack V1.15.03 installed, which I can start and run from the STM32CubeProgrammer.

Advice on how to debug this would be welcome.

Hello,

If you try with an example available in STM32CubeWB package, is it working?

Best Regards
