How to transition from FUS to Stack in a bootloader? I am unable to restart the stack.
I am trying to set up a bootloader where I can transition CPU2 to FUS, then back to the wireless stack. I followed the examples of sending 2 FUS_GET_STATE commands to enter FUS. Then I send the FUS_START_WS with the SHCI_C2_FUS_StartWs call. Nothi...
STM32WB bonded devices information is lost after core2 firmware update
