Modem Reset Loop With Asset Tracker

[mmelv]

Hello,

I'm running into a problem where every time I run the asset tracker the modem reset loop is triggered and I have to wait 30 mins before I escape. I've read the modem reset documentation https://infocenter.nordicsemi.com/index.jsp?topic=%2Fnwp_042%2FWP%2Fnwp_042%2Fintro.html but I don't know how I'm supposed to avoid this problem. The terminal output doesn't indicate that the modem is resetting 7 times (unless it's happening to fast). I've been working with the asset tracker for a few weeks now, I've encounter this problem before but it usually goes away, but now it's persisting. 

Also I was previously able to circumvent the 30 min timer by using the nRF Desktop Programmer tool to erase everything, then do the AT Command quick start to get the modem running again but this also no longer works.

Any help would be greatly appreciated!

Hi,

Do you use VS Code? Is there a difference if you do not use "Erase and Flash" in VS Code but use "Flash" instead?
With regard to Programmer application, you could try to deselect "Auto reset".

Thanks for the response. Yes, I am in VS Code. However, when I attempt to flash without erasing I get the following error:

I also tried using the programmer to erase (after disabling auto reset) and then flash without erasing but that still leaves in in the reset loop. When I started working when I was stuck in the reset loop, do I need to wait the 30 mins and then retry the programmer with auto reset deselected?

Hi,

When reset loop restriction is triggered, the restriction is written to NVM and waiting time cannot be bypassed. You would need to wait 30 minutes. Regarding your error, after timer expires, you could try to use west flash command with --recover. If you use nrfjprog for programming, you could try to add --verify.

Best regards,
