MCUBOOT Hello world

[Learner]

Hi,

I downloaded the hello_world_with_mcuboot.zip file that Simon provided in one of the ticket few days ago - Case ID: 283917.

I built hello_world_with_mcuboot project in Segger Embedded Studio (SES) and flashed the merged.hex file in the dev board nRF52833DK. Unfortunately, it is not behaving as expected.

1- I am not seeing the "Hello World!" message.

2- Each time I stop the debugger and restart by clicking 'Go' or F5 I get prompted with the message

"The project zephyr/merged.hex is out of date and needs to be built. Build the project before debugging?"

But I am sure nothing has changed in the project since the last build.

Note, I have not changed anything in the project you provided in the zip file. 

Kind regards

Mohamed

Thank you Simon.

Now when I use the nRF52833DK board I can see the debug logs with both J-Link RTT Viewer V7.58B and SES Debug Terminal. However, when I flash it on our target board (based on nRF52833 SoC) I can see the debug logs in RTT Viewer but not in the SES Debug Terminal. Also, when I flash the same .hex file to our board that uses the secure B version of the nRF52833 SoC I don't see any logs in either RTT Viewer nor SES Debug Terminal.

Finally, I would like you to comment on my question 2 above.

Thank you

Hello Mohamed,

Sorry for the delay on this. I don't have an nRF52833 at hand at the moment but I will try to get ahold of it tomorrow and try to reproduce the issues you're seeing.

Best regards,

Simon

Hi Simon,

Don't worry. I have managed to sort it out.

Kind regards

Ah, okay. I'm happy you figured it out
