Unable to update thingy91

[TilakL]

Dear Nordic,

I am trying to update the Thingy91 by following these steps developer.nordicsemi.com/.../thingy91_gsg.html

At step 12, the "Write" option is greyed out as shown in the picture. Any idea why?

I have PCA20035 v1.0.0 and my end goal is to run the latest modem with the latest Asset Tracker V2 to study the LTE-M coverage/performance in my area with Nordic chipset.

Some history:
1) Earlier I had an old modem: mfw_nrf9160_1.3.1 with Asset Tracker v1.7.0 with all the sensors enabled without the GPS. Works flawlessly.
2) Updated to the latest modem: Tried FOTA using nrfcloud.com but it was cancelled, I am not sure why. So, I tried to update via USB cable by pressing SW4 and power switch and I was able flash mfw_nrf9160_1.3.4.zip successfully.
3) Now my thingy91 LED does not glow, nor the LTE link monitor works.
4) So tried the procedure from the beginning and I am stuck at Step 12, where the "write" option is greyed out developer.nordicsemi.com/.../thingy91_gsg.html

Kindly help.

Thanks,
Tilak

Hi,

It is recommended to update your application firmware to asset tracker v2. Additionally, you could try the procedure described in the guide without using nRF Cloud.

Dear Dejan,

I have tried with the USB cable but it does not seem to work with the latest nRF Programmer tool as the "write" option is greyed out. Is this a bug with the nRF programmer v3.0.7 or is this a known problem with Thingy91 v1.0.0 hardware?

Kindly help.

Thanks,
Tilak

Hi,

I have tested updating procedure using nRF Programmer application v3.0.7 and Thingy91 PCA20035 v1.6.0. I could not reproduce the problem. You could try using some other version of Thingy91, preferably a newer one (v1.5.0 or 1.6.0) if you have it available.

Best regards,
Dejan

Thank you Dejan,

Unfortunately, I do not have access to the latest hardware.Interestingly, I tried with the latest Debian laptop, the "write" option shows up but the /dev/ttyACM0 needs chmod u+x everytime. But then the MCUBoot does not respond even though the transport is up. The UI does not show the MCUBoot but only shows the version 0.0.1.

Next steps, I am thinking of going back to the old version of the tools that I had used (back when it worked). Otherwise, I am thinking of using the jlink debugger to get the MCUBoot back to life.

In the meanwhile, if you have any pointers on how to recover the thingy91 that would be great.

Thanks,
Tilak

Hi,

Have you followed all 3 recommended steps outlined in programming section for Thingy91?
What is the result?

Best regards,

Hi Dejan,

I have tried to flash with the external debug probe as recommended in the above link. Using all the latest software tools and binaries. The flashing process was successful but there is no sign of life on the Thingy91. There is no data coming in on the nrfcloud. I tried the LTE Link Monitor, I am able to connect to the COM port but nothing shows up, even a simple AT command does not work.

Attached is the log of the flashing process.

Kindly help.

Thanks,
Tilak

ps: Going back to nRF Connect Desktop v3.8.0, does not install the old nRF Programmer v2.0.0 but instead picks up the latest v.3.0.7. So, there is no way for me to check for regression when flashing via USB.

Hi,

You could try serial LTE modem and asset_tracker_v2 samples to verify the operation of your Thingy91 locally.

Have you tried following the guide without external debug probe?

Do you have any other Thingy91 device which you could use for testing? 

Could you please provide information about the log?  Which command/tool did you use for flashing?

Best regards,
Dejan

Hi Dejan,

I tried with another thingy91 where I was able to update the asset_tracker_v2 and able to receive data in the nrf_cloud.

Meanwhile, please recommend how to recover the original thingy91 where flashing with external debug probe worked and the USB write is still greyed out in the progammer. 

Thanks,
Tilak

Try turning the device OFF/ON again and perform the steps from the guide without using external debug probe.
