Debug mode terminating after Radio.Rx() func. called

[mrkayaalp]

hello everyone, I am currently working on a board that I designed based on the double-layer reference design of MB1874-LP. The board is almost identical to the reference design.

After finishing the layout of the board, I uploaded the draft code I wrote in STM32CubeIDE to the board. I used the SUBGHZ_PHY middleware that I saw in the sample codes of STM32WLE. The code I wrote inside the "SubghzApp_Init()" function is as follows:

When I run the code in Debug mode, I encounter a "target not found" error and lose connection to the debugger when I reach the Radio.Rx() function. I also encounter the same problem when trying to start in transmit mode. I wonder what the problem could be caused by.

Hello @mrkayaalp and welcome to ST Community.

I suggest you to do a double check on your HW to make sure you don't have electromagnetic interference or electromagnetic compatibility issues or ay other HW  problem. Also, take a look on the state of the  Solder bridges SB2, SB10 and SB12. For the code, can you try without [rf_mod(rf_rx);].
