Facing an issue while flashing the code using segger debugger

Hi Akhilesh,

I believe this lesson should be enough to get you started atleast https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-2-debugging/

It might be some work to port it from being used with a DK to your module, but it should be possible

Kind regards,
Andreas

Hi Andreas

How could I analyze the firmware crashing after flashing and how to understand that could you help me with it?

Regards,

Akhilesh

Hi Akhilesh,

I'm not familiar with the module you're using. I would suggest that you do some debugging and fetch some logs. It might be that the firmware crashes before it does any code execution when putting it into the board.

From the PS of the module the GPIO looks to be ok to use for anything you wish, i.e it's fine to connect it to the LED.

Kind regards,
Andreas

Hi Andreas

Thank you so much for your input I will update the version and try again.

But my doubt is still unanswered as I was able to flash the code on the I/O Shield and I was able to read the memory of the I/O Shield. still LED connected to P0.31 didn't turn ON. I couldn't able to understand the issue. I have checked with the LED also working and tested the code on the nRF5340 Dk board and LED Connected to P0.31 GPIO was blinking there.

Akhilesh

Hi,

From what I can see the EDU Mini should support cortex-M33, so in theory it should work.

From your logs it looks like it might be a MAC OS issue, but it's just the recover function that seems to be going wrong.

WARN Installed JLink version does not match the expected version (JLink_V7.94e)

WARN It looks like you have installed JLink using 64-bit Apple M1 Installer, but currently we only support their Universal Installer for your system.

WARN Please install JLink: https://www.segger.com/downloads/jlink/JLink_MacOSX_V788j_universal.pkg

Could you

Make sure that the Jlink version is up to date
Then try with some simpler commandoes with nrfjprog or nrfutil, for instance nrfutil device --recover

Kind regards,
Andreas

Hi Andreas,

I have flashed the code over the I/O shield using "Programmer Tool" in nRF Connect for Desktop. after flashing the code is still LED Connected to P0.31 was Not Switching ON. The voltage coming on that pin is 0.28v, I have flashed the Zephyr.hex file over the I/O shield. but for testing when I was trying to flash the merged.hex I am getting the error.

Following is the error log I have attached for your reference:

RE: Facing an issue while flashing the code using segger debugger

Hi,

https://docs.nordicsemi.com/bundle/ncs-2.7.0/page/nrf/config_and_build/programming.html states "To program the output build files to your device, which in most of the cases will be zephyr.hex or merged.hex, use the steps for the development environment." and you can see the output build files here: https://docs.nordicsemi.com/bundle/ncs-2.7.0/page/nrf/config_and_build/configuring_app/output_build_files.html#app-build-output-files

For a multi core application you can see in the matrix in the later page that merged.hex is what you want for a single file that contains all the images you need

Kind regards,
Andreas
