Hi Oyvind

Any resolution to this issue? I am getting the same error message when trying to update modem firmware. No lights. Getting this error:

MCUboot DFU failed. Please make sure that the device is in MCUboot mode and try again

I do not have a segger debugger..... Thx Jim

Hello Øyvind,

I'm quite deceived by this situation, I am also having the same issue, but I don't have a debug probe and I wasn't planning to buy one, at least now that I'm just doing a first evaluation of the Thingy:91.

Are there any news? An updated driver? Or could I try to install the programmer and driver on a different PC? Any hope to solve the issue in another way?

Thanks very much for your support.
Best regards,

Andrea

Day after update:

I did further tests, I tried a Windows 8 and even a Windows 7 (32 bit) PC. Unfortunately I had exactly the same failure. Of course without the modem update the Thingy is not even connecting to the network, so I'm totally stuck in my evaluation. I wonder if it would be even worth trying a Linux PC...

Indeed. I purchased a segger j-link external debug probe and it worked. Thank you for your help.

Hello,

I've been investigating, and this issue seems to a driver issue in Windows which incompatible with your current version of MCUboot on the device. The only workaround at the moment is to program the modem using an external debug probe and/or update the MCUboot in a similar manner, programming the application with an external debug probe.

Kind regards,
Øyvind

The key point is that even though I am using the correct modem fw (mfwnrf9160120.zip), I keep receiving the error message :"Please make sure the device is in MCUboot mode and try again".

And, the Thingy:91 is in MCUboot mode because the blue LED is OFF.

That is the problem. It is not clear to me how to resolve this problem. Is there a workaround?

[quote user="sab"]Isn't this zip file the precompiled FW?[/quote]

No, the thingy91_fw_2020-04-29_bc7ade8b.zip is the precompiled FW folder, while the mfwnrf9160120.zip is the modem FW (mfw).

Hi Oyvind,

Thank you for your reply.

I'm not sure exactly what you mean by 'precompiled FW'.

When I clicked on the link you provided, it eventually took me to the file: thingy91_fw_2020-04-29_bc7ade8b.zip. Inside this file is the modem firmware file: mfwnrf9160120.zip. Isn't this zip file the precompiled FW?

Perhaps you thought I was trying to update my Thingy:91 with a new application file? I'm actually just trying to update the modem firmware.

Thanks,

Sanjay

Hello,

Have you tried to update the application using a precompiled FW first? I will talk to our Thingy:91 team.

Kind regards,
Øyvind
