Hello,

Your prj.conf and main.c file looks good. Is this because of any wrong configuration you tried inside the RTT viewer (see the screenshot below)? Is there any another active JLink connection while you are trying?

Please expect some delay from our side as we very thinly staffed due Easter Vacation here in Norway.

Kind Regards,

Abhijith

I have erased the MCU via J-Flash Lite Segger tool and after flash again application, problem is still present no output in RTT viewer (MCU is detected correctly by RTT viewer but no data in terminal), it does not seem that MCUboot is present because does not enter in DFU mode as it happened before erase. Anybody have more ideas?I am realy tired with this issue.

How can i check RRT out from the bottloader?I am using bootloader witch is install by default in the PCB. Do you know how can i write then in the RAM RTT block from APP?

Thanks!

Do you see RTT output from the bootlader? It is possible that the app never overwrites the RAM used by the bootloader RTT block, which causes the desktop software to not detect the bootloader->app change.
