Thingy 52

[renan.fazzani]

Hi, we recently purchased a Nordic Thingy 52 module and were trying to program it. We used a J-link recorder and a cable for the connection between the J-link and the Thingy 52, according to the pin indicated on the electrical diagram, connector J9.

That way the card works a few times after the connection is made, and after a few more attempts to record it does not turn on anymore.
We have already validated the voltages in the processor, they are correct, as well as there are no signs of burning of any component.
We would like a feedback, a help on what may have happened with the Thingy 52.

Hi Renan,

erase the Thingy device & flash this hex file to the Thingy. You can either do this via nrfjprog or nrfgostudio.

You can also see this case.

Best regards,
Kaja

hi, i only have the nordic thingy 52 module, do i need more development boards to be able to program with j-link?
or can I write the firmware through the DFU?

[Kaja]

Hi Renan, 

sorry for the delayed answer, I was OOO. 

No you can use the j-link, and use the debugger interface. 

If you buy the nRF52 DK, you can also use this to update the firmware of Thingy using the built-in J-Link OB debugger. 

Best regards,
Kaja

hi Kaja, no problem. Thanks for the answers.
I bought a cortex m adapter to use with my j-link. I'll be back with results soon

Hi Kaja,

i connected my j-link to the nordic board thingy 52 through a cortex M adapter, nrfgo studio recognizes the J-link, however my nordic board does not appear as an option so that I can program it.

Below is an image of how the nrfgo studio looks.

If you can help me, I'm grateful.
