THingy:53 not able to detected in nRF Programmer

[Divya_uni_ulm]

Hello,

Initially I was flashing software for peripheral_LBS by connecting Thingy directly through USB.

Later as per project requirement I tried to flash the code using VSC and somehow after that if I want to flash a precompiled firmware file to thingy USB then nRF programmer no longer detecting the Thingy.Even Though I am pressing the SW1 and SW2 together as mentioned here:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_thingy53_gs.html#getting-started-with-precompiled-firmware-samples

but still it is not showing the device.

What do you think could be the reason of this issue?

Hi Divya,

Did you use an external debug probe when programming the Thingy with VS Code? If so, did you make sure to program the device with a sample or application that included MCUboot?

Hello Marte,

Yes, I have used external programmer that is Jlink and I have tried to upload the code provided in this link:

https://github.com/nrfconnect/sdk-nrf/tree/main/samples/bluetooth/peripheral_lbs

and it has been flashed successfully and since after that the device is not detectable.

Hello Marte,

Thanks for the reply, 

I found that. Also,

I am using peripheral_lbs sample code here and my device is not detectable when I am using thingy53_nrf5340_cpuapp_ns as in build configuration.

Hi Divya,

Edit: I believed I had reproduced the issue, but it seemed like my issue was related to something else. So I am able to use MCUboot to program the Thingy even when building as non-secure.

Do you see this happen with other samples as well?

Hello Marte,

I have tried testing with the Thingy:UART sample using thingy53_nrf5340_cpuapp configuration.

But now it is showing me the error like:

Also, it is showing an error in the source file of UART sample:

Can you please help me to resolve this issue? because I can try with other configuration until I will resolve these issues.

Thank you in advance.

Also, When I have tried the Thingy:UART sample using thingy53_nrf5340_cpuapp_ns configuration then it is successfully flashing the code but on the other hand the problem with thingy53_nrf5340_cpuapp_ns configuration is same. Again my device is not my device is not detectable when I am using thingy53_nrf5340_cpuapp_ns as in build configuration.

Can you share the entire build log with the error from the UART sample?

How are you programming the Thingy:53 when using the external debug probe? Do you use the "Flash" action in VS Code, run west flash in terminal, use the Programmer app, etc.?

Best regards,

Hello Marte,

Both the issues has been resolved now.

But I need to confirm that for Bluetooth: Peripheral UART:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/bluetooth/peripheral_uart/README.html#testing

As mentioned here:

 

Do we need any external board? or only Jlink debugger and Thingy Device will be sufficient?

Hi Divya,

Yes, you need to use the debug board and an external USB to UART converter as is described in the documentation. However, the debug board mentioned is the one that is provided in the Thingy:53 kit (to the right in this picture):

So you only need to get the external USB to UART converter.
