We dont require any of the RF features in our use case. Had to choose this MCU due to chip shortage. Just want a functionality of a regular STM.Can we just use application core independently ?Is it possible to disable RF (Bluetooth radio ) completely and run the other core ? Please advise.

Hello,

Yes, it's possible to disable RF core and run only application core, to disable RF core, just don't start it

by removing CPU2 initialization (appe_TL_Init and MX_IPCC_Init) in application side and initialize the CPU2 reset value to shutdown like this:

 LL_C2_PWR_SetPowerMode(LL_PWR_MODE_SHUTDOWN);

Best Regards
