Can't flash asset tracking sample code getting the fatal error.

[purushothaman]

Hi,
     im using nRF9160dk ,sdk version 2.5.1 .When I open the sample code of  asset tracking v2 application code I can successfully build the code but when I tried to flash the code I'm getting this fatal error ,but I can flash remaining code like nRF cloud multiservice code and all sample codes successfully and got output also but why I can't flash asset tracking code.below I shared the error.

Hi,
     after updating the modem version 1.3.6 and sdk version to 2.6.0 also this time flashing asset tracking program getting like this what to do?

Hi,

What you mean "getting like this"? Do you mean you still get "FATAL ERROR: command exited with status 25"?

If so, could you try to build original "v2.6.0\nrf\applications\asset_tracker_v2" then recover board before programming?

Best regards,

Charlie

Hi,

  After updating, I didn't encounter the fatal error this time. Instead, I received output in the serial terminal as shown in the screenshot. So, in addition to my previous question, I'd like to confirm if I still need to perform board recovery as shown in your screenshot, considering that I didn't receive the fatal error this time. My concern remains that while the nRF Cloud multiservice sample code is working fine, only the asset tracking sample code is encountering issues.

Hi Purushothaman,

Yes, please do it and try to build then program original "v2.6.0\nrf\applications\asset_tracker_v2". Let's see what will happen.

You can also find a prebuilt Assert Tracking v2 sample from nRF9160 DK application and modem firmware download page:

Hi,
    Thank you for your guidance. I followed the steps as suggested, including building the original asset tracker v2 code and performing board recovery before programming. However, I'm still encountering the same issue as before.I'm not receiving any output indicative of cloud connection or data publishing.

I also attempted to directly flash the asset tracking code from the nRF desktop,

but unfortunately, the results remain unchanged. Given these outcomes,

do you have any further suggestions or troubleshooting steps I could try to resolve this issue?

[Charlie]

Could you share me you nRF9160DK hardware version? 

This may be related to external flash Application description — nRF Connect SDK 2.6.0 documentation (nordicsemi.com).

Best regards,

Hi ,

Thank you for your prompt response. My nRF9160DK hardware version is 1.1.0. Based on this information, could you please advise me on the next steps I should take to resolve the issue? Your guidance would be greatly appreciated.

Best regards,

Hi Purushothaman,

I am also using nRF9160DK v1.1.0 now.

Could you give a last try by programming thingy91_asset_tracker_v2_2024-03-13_af2b60d2.hex  with nRF Connect for Desktop->Programmer APP.

If it still gives the same result, I also run out of idea why this happens.Please send me pictures of your nRF9160DK from both sides, just in case it is some HW issues.

Best regards,

Charlie
