nrfjprog --program fails when FDS and LESC are used

[jmac2025]

I've pulled FDS and LESC into my development project. I've noticed now, when I do --reset --sectorerase --program "#H" --family NRF52 --verify, occasionally I see program fail. And example of the application and the devices flash upon failure:

Has this been noted  before? Is there a reason why this would happen with the inclusion of LESC?

Hi, 

Are you using the custom board or an nRF52840DK?

when I do --reset --sectorerase --program "#H" --family NRF52 --verify, occasionally I see program fail.

What nrfjprog version are you using? Could you update to the latest version https://www.nordicsemi.com/Products/Development-tools/nRF-Command-Line-Tools/Download#infotabs?

If that cannot help, could you provide the log by your command with "--log"?

Could you try to use the nRF Programmer app to flash? Do you also get failed? If so, please also provide the log. 

Are you using the nRF5 SDK? Could you try to erase all  (nrfjprog --eraseall or nrfjprog --recover) before programming?

Regards,
Amanda H.

• I am using a custom board 
• I am using the latest nrfjprog 
• I am using the nRF5 SDK
• eraseall and recover do work, it only fails with sectorerase. This did not occur before
• below is an attached log file
• 7181.log.log

here's an example of what I see in Keil (this is not from the above log)

Check out this post.

But I'm already doing a --sectorerase and I'm still seeing this issue

Then, you need to erase all and recover before programming.

Is there a reason why this issue is arising when FDS and LESC was added to the project?
