SubGhz Ping Pong Dual Core

[Edmond_Dante]

Hi All,

We have designed a board using the STM32WL55CCU6 [UQFPN 48 pin] chip and successfully brought it up. We have tested the USART, and it is working correctly. However, when we try to port and run the example of SubGHz Ping Pong Dual Core, it does not work as expected. The program gets halted after calling the function "MX_SubGHz_Phy_Init();". We followed the procedures outlined in the readme file which I had added along with the query. The modifications for the files are done as mentioned in the readme but the switching between the cores is not happening. I am adding a file where the program is halted.

Can anyone provide the correct procedure for this?

Hello @Edmond_Dante 

First, have you verified that you have no Design issue? if no, please contact an RF HW expert to do this.

Also, ensure you are following the procedure as it is by testing the example on the Nucleo board. 

Best Regards.
