Thingy 91: unable to update modem firmware with mcboot

Dear Didrik, thanks for your fast answer!

I could program the modem firmware with the j-link without problems! I didn't know I just needed to deselect MCUBoot. The edu mini is a great little interface!

I am not sure where to check the hardware version, the protocol says NRF9160_xxAA_REV2 and the sticker on the board 1.4.0 and 2020.24.

Though I am happy with the update process over the j-link, I could try to program the unit again with USB/MCUBoot to check if the error persists if you'd like.

Hi,

I can't remember seeing that failure mode before. Usually, it would work, or you would get a

I'll ask our developers if they know what is wrong.

What (HW) version of the Thingy do you have?

But, you should be able to use your J-Link edu mini as well.

If you uncheck the "Enabel MCUBoot" checkbox, are you able to select your J-Link and update the modem that way?

Best regards,

Didrik

Unfortunately in my case Windows 10 did not help. I waited for minutes and the update did not pass step 1. nRF Connect 3.6.1.

Update:
I've just set up a windows 10 machine and have been able to successfully update the firmware. It paused after step 1, but continued to step 2 after a few seconds.

nRF Connect v3.6.1 - Programmer
nRF Connect sDK v1.4.99-dev1

FW 1.2.2

I hope this helps.
