STM32WB55 CPU2 flash size

[metal2oxide]

How much flash memory is allocated for CPU2 flash and is it possible to write a RF firmware without involvement of CPU2

[TDK]

CPU2 is not designed to run user code. It is allocated the second half of the flash by default, although this is adjustable.

Hi,

Allocation depends on RF stack you choose. You can find RF firmware size on %HOMEPATH%\STM32Cube\Repository\STM32Cube_FW_WB_V1.12.1\Projects\STM32WB_Copro_Wireless_Binaries\STM32WB5x\

I think you can't use RF with CPU1 only.

what is the minium allocation which needs to be done for second core. I want CPU1 core to use the max flash
