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.
