Hello_world and other samples do not build properly for thingy53_NRF5340_cpuapp_ns

[henning larsen]

I cannot build the hello_world sample (and blinky for that matter). Target I have tested here is thingy53_NRF5340_cpuapp_ns. Everything is installed according to the recommendations using the nRF connect for desktop. The version of sdk is v.2.4.1

In VS code, I create a new application hello_world. Seems to work fine.

Add a build configuration for nrf5340 (thingy53). It generates 19 "problems" - out of the box - so to say.

I have thingy connected via Segger J-link Plus. J-link plus can access the thingy53/nrf5340 and download code. But this is no use when the code is broken.

Unfortunately there is no direct way to copy the "PROBLEMS" list to a file (would you believe !) from the darn VS Code (*1) so I have added a picture.

I have similar performance when building Blinky for same target. I have no interest in trying other targets as we will be using nrf5340.

Any ideas what I am missing? Looks like some path or configuration error but I am clueless as to what it can be. Should this not just work without further editing and with zero warnings?

(*1) It appears that I have to install an extension to copy the PROBLEMS at a textual listing - this is sort of - silly!

Here is support dump: Slight edited wrt. paths

Hello,

Yes, I tried this here and was able to produce the same error you are getting.

It looks a bit strange to me. I think it is because the bootloader is crashing while setting the breakpoint. But I am not sure of the root cause. So I will discuss this with my colleague and try to ask this internally.

Kind Regards,

Hi everyone,

I am encountering the same error when trying to debug all my three Thingy53. They worked off-the-shelf and I managed to flash the blinky example a couple of times into all of them but then suddenly they stopped working properly. Now, even the blinky example does not work. The flashing process completes (via external debugger and USB) but has no effect. When I try to debug, it gives me the issue with fih_panic_loop. I am using Visual Studio Code on Windows 10, but I also tried Ubuntu, and the problem is the same. As external debuggers, I used nRF52840DK and nRF52833DK. Is there any way for a factory reset?

For thingy53, you need to use an external debugger that supports Arm cortex-M33; see here. You can use nRF5340dk, but the DKs you mentioned cannot be used as an external debugger for thingy53.

Hi Abhijith,

thanks for your reply. Unfortunately, I did not pay attention to that.

Does it mean that my Thingy53s are damaged now?

I don't think this will break your device. Try to program your device with a precompiled file that comes with thingy_firmware. See the sections on updating through BLE and updating through USB.
