Uploading using J-link on custom board.

[Niels Redegeld]

Hello, 

I am trying to upload code to a custom board using a SEGGER J-link device. I have tried doing this using VSCode and the nRF connect extension, I have tried using J-Flash Lite and I have tried using nRF connect for desktop. Is there a clear tutorial about how to upload to a custom board (I have found one where you make the devicetree for a custom board but it doesn't tell you how to upload it.) Or can someone point me in the right directions?

Kind regards,
Niels Redegeld

Hi Niels,

Please take a look at the following : https://www.youtube.com/watch?v=V_dVKgWKILM and  Programming a custom board with an NRF52840 dev kit

Hi Swathy, 

I have looked into both and it still doesn´t seem to work, when i try to erase the chip on the nrf connect app for pc i get the following error:

12:53:32.166

Recovering Application core

12:53:32.168

Failed to recovering application core core. Error: [object Object], message: Batch task recover failed, [jlink] JLINKARM_DLL_ERROR

12:53:32.351

Error: Task failed. One or more batch tasks failed: - [jlink] JLINKARM_DLL_ERROR, code: Nrfjlink. Message: Batch task recover failed, [jlink] JLINKARM_DLL_ERROR.

Do you happen to know what goes wrong if this error shows?
