Thingy:53: Programming

[Yurii_B]

Requesting help on Thingy:53.

I have couple of boards. I was able to program all of them. For programming I use VSCode or prgrammer with precompiled firmware.

Now, scene enters Thingy:53. I have tried all methods of programming. VSCode & Programmer (hex) & Programmer (MCU bootloader).

None of them ever did start BLE module. I seem to have device connected, just not able to program it.

I can see device when I connect via cable & nRF52DK. Meaning Updating through external debug probe. Meaning using 10-pin 2x5 socket-socket 1.27 mm IDC Serial Wire Debug (SWD).

I cannot see bootloader in programmer, as described Bootloader Thingy:53.

I carefully followed instructions from developer.nordicsemi.com/.../thingy53_gs.html

Screens show I tried using precompiled downloadable firmware.

None helped.

What I might be doing wrong?

Using nrfutil-device version: 2.0.3
Using nrf-device-lib version: 0.17.3
Using nrfjprog DLL version: 10.23.1
Using JLink version: JLink_V7.88j

Hi Yurii, sorry for the delay.

Are you able to build and flash the blinky sample using VS Code?

Check out the nRF Connect SDK Fundamentals course on DevAcademy. Exercise 2 will take you through the necessary steps for building and flashing blinky.

I can build and flash all samples to my other devices. I can use nRF5340DK, nRF52 DK & Thingy:52. Only Thingy:53 is not seem to be working fine.

I did go through all of the fundamentals. I assume something is different with Thingy:53 specifically that I cannot seem to be able to flash it.

Hi Yurii, sorry for another delay.

Try the following:

Connect nRF5340 DK via USB and Thingy:53 connected via debug cable (powered by USB and turned on). Download the attached merged.hex and program it the following way.

nrfjprog -f NRF53 --program merged.hex --chiperase --verify --reset

You should now see the LED on Thingy:53 flashing red. If this works we at least know that you are able to flash the thingy.

Try using nRF5340 DK if you have that board at hand. When using an old nRF52 DK that had not been updated I was in some occations not able to flash Thingy:53 properly.

You could also try to build and flash blinky from VS Code with nRF5340 DK and Thingy:53 connected via the debug cable.

Seems like device is still the same.

I did try precompiled FW. Blinky. Still the same, no lights, no response. That is from start I cannot flash that device. All others are fine.
