Cannot flash my board nrf5340

[Marika Di Martino]

Hi, I have changed Vdd from 1.8 V to 3.3 V but now I cannot flash anymore my board (nrf5340). This is the output error:

* Executing task: nRF Connect: Flash: AppCore_RHS_SD_UI_v1B/build (active)

* The terminal process terminated with exit code: 33.
* Terminal will be reused by tasks, press any key to close it.

I have tried to erase the board but I get this message: Error erasing device. See the Output tab for more details.

What can I do?

Thanks

Try these things

`nrfjprog --eraseall`

`west flash --recover`

Paste outputs 

[Marika Di Martino]

These are the outputs I got in both cases.

Okay, can you collect the log and send the output?

Or, can you install NRF Connect for Desktop Application --> Under this install Programmer, try to erase all and see the log output. It mentions low voltage or something, then its power supply issue. 

If not, try to change the debugger unit/check for loose connections.

This is the log output. Yes, I also think the problem is related to the power supply because I got this problem about flashing after that I changed the Vdd form 1.8 V to 3.3 V.

Hi,

Can you provide some details about your setup?

Can you provide more information about your power supply? 

Do you see the same problem if you return to 1.8 V?

Do you have any other board to test with?

Can you try to use "nrfutil device" for erasing and recovering as shown in this documentation page?

Best regards,
Dejan

[Marika Di Martino]

Hi, I didn't change anything else, just the power supply. When I try to return to 1.8 V I get another error. I don't have any other board. This is the output when I use "nrfutil":

Hi,

Can you show this error?

Marika Di Martino said:

Is this output from "nrfutil device" when you used 3.3 V or 1.8 V? Can you show the output also when using other voltage?

Best regards,
Dejan

[Marika Di Martino]

The output is for 3.3 V. I cannot return to 1.8 V because I get this error:

Hi,

You sent logs where you used nrfutil for recoovering and erasing only in case of 3.3 V. Can you show the logs of "nrfutil device" when you use 1.8 V instead?

Best regards,
Dejan
