Hello, 

Could you please confirm that you are using the correct SDK ? Could you please confirm the version of the SDK? 

Regards

Yes, I am using the proper SDK, from which I have already tried and tested a few other examples that worked fine. However, after I created a custom example and flashed it, this problem arose. this is the version of the sdk i am using SDK_2.16.100_RD-RW612-BGA.

The last flashed program is working fine, and I can still see its debug logs. However, I am unable to flash a new program onto it.

Hello,

Could you try doing a mass erase? This can be done with the GUI Flash Tool.

You could also try using an external J-Link debugger through J19.

Please make sure RF_CNTL_2 is set to 1 as stated in the schematic.

Best regards.
