nrf5340 audio application flashing using SWD

[Adarsh_1]

Dear team,

I am not able to flash the nrf5340 audio application (gateway) to the nrf5340 Audio DK using SWD from nrf5340 DK. I nrf5340 DK outputs 1V8 logic. 

I can see that both the application core and network core was programmed properly, but however the LEDs on the back of AudioDK lights red and the application does not run anymore.

I tried flashing a couple of times with no success.

Is it possible to flash an nrf5340 Audio application to nrf5340 Audio DK or any other custom board using SDW interface and not the USB?

Best regards,

Adarsh

Hi Adarsh

Any particular reason why you can't use the USB debug option?

I can't find any references to external debuggers in the documentation so I am not sure if this is supported, but I will check with the developers and get back to you.

Hi Adarsh

Using an external debugger should be possible, just make sure you use the 10-pin connector on the side (P12), not the top connector (P13).

Hi Torbjorn,

Thanks for your response. I have been using test points 23 and 24.

I confirm that the firmware flashing was already working. The problem was with an error in my code. 

Now everything is working as expected. 

Best regards,
