Pingpong subGhz dual Core Example

[BNamu.1]

Hello I have two STM32WL55JC2 boards and I would like to run the PingPong DualCore example available in this WL package folder :

 I run the .project file on the STM32 IDE and I get this: 

After adding several missing .h files I manage to flash to the boards but I think I am missing a step.

In the tutorial it says: 

"

 - Open your preferred toolchain

 - Rebuild all CM4 files and load your image into CM4 target memory

 - Rebuild all CM0PLUS files, set PWR_CR4_C2BOOT flag via CM4 and load your image into CM0PLUS target memory

 - Do the same for second board

 - Reset the two boards

 - Run the example on two boards

 - Open two Terminals, each connected to their respective PingPong Device

 - UART Config = 115200, 8b, 1 stopbit, no parity, no flow control

"

It's not working from now on and i think i've missed something but i can't find what.

"Rebuild all CM0PLUS files, set PWR_CR4_C2BOOT flag via CM4 and load your image into CM0PLUS target memory" i don't know how to do this line if someone can help me !

if anyone has a simple video to start this example i would be very happy !

Thank you
