Thingy91 not Programming

Balabobot

Hi,

I follow the instruction to update the https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_thingy91_gsg.html 

Updating the firmware in the nRF52840 SoC and following through the USB method.

I don't have the 1.27mm cable to follow through with the external debug probe method.

But, When i select the device with Enable MCU Boot Selected, i get the below error.

19:41:22.451
Target device closed
19:41:44.676
Error while setting up device 0.01: TypeError: Cannot read property '0' of undefined
19:41:44.676
Target device closed.

    Hi,

    My understanding is:

    1. You've used a debug cable between the nRF9160 DK to program both the connectivity fw on the nRF52 as well as the modem fw on the nRF9160 + the application.  But you're still not able to get it to connect to nRF Cloud. You've done the same with the nRF9160 DK and are able to get a connection. 
    2. You've tried using the USB method by just connecting a USB cable to the thingy:91 but you say that the device doesn't appear on the nRF programmer app. 

    Questions:

    1. Could you try the same on another computer? The result would indicate whether the issue is with your Thingy:91 itself or your computer configuration etc.
    2. Can you try to reinstall nRF Connect Desktop. Make sure to delete all of the plugins by deleting all of the files from C:\Users\<user>\.nrfconnect-apps.

    regards

    1. i have to try it a VM, i dont have another computer per say

    2. I have tried re installing, i will try deleting plugins

    3.I was able to get data of Thingy91 to nRF cloud, my problem is it doesnt get detected in the nRF desktop programmer or LTE monitor.

    4.I have used DK to program thingy91 via 1.27mm SWD cable every time

    5.Can you tell why the thingy91 uart doesnt load driver as in my posts?

    It would be best if you were able to test it on another computer, using a virtual machine would just complicate this even further I think..

    Great,

    Ok, so at some point you've been able to flash the Thingy:91 with the correct fw? Did you use the USB or a debugger + SWD interface?

    Ok, so previously you had the 1.27 mm SWD cable and could update the Thingy:91 by using the cable and the onboard debugger on the DK, but now you want to use the USB instead but the device is not listed correctly in nRF Connect Programmer.

    I'm not sure, it should in most cases work straight-out-of-the-box. 

    Can you share a screenshot of the device in the device manager list. Does it say that it can't find the drivers for the device, is any errors displayed?

    Also what Operating system are you running, which version?

    regards

    2. I have windows 8

    1. The thingy91 worked on another pc and nrf was able detect it right away.
