Is it possible with CubeIDE to program both cores of the STM32WB55CC? I would like to abuse it as a simple dual core processor without the BLE stack. Just write two bare metal programs, one for each core, and run them. Is this technically possible?

Hello,

It's not possible to use CPU2 like this, CPU2 is not accessible.

On the other hand, I think it is possible to use both processors on STM32WL55 - the LoRa / sub-GHz targeted products.

Whilst I have never done this, I see example applications SubGHz_Phy_PingPong and SubGHz_Phy_PingPong_DualCore (where there is separate code for CM4 and CM0+ cores).

I don't know why ST chose to make the WB55 different in this respect.
