Cannot flash my board nrf5340

Hi,

It could be useful to know which error you get at 1.8 V.

Can you provide details about your board and power supply?

Best regards,
Dejan

Hi, I cannot return to 1.8 V because I get some errors. Before setting 3.3 V (so when I was working with 1.8V), everything was working.

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

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

Hi,

[quote user="Marika Di Martino"]When I try to return to 1.8 V I get another error.[/quote]

Can you show this error?

[quote user="Marika Di Martino"]his is the output when I use "nrfutil"[/quote]

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

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 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

devzone.nordicsemi.com/.../6443.log.log

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.

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.

These are the outputs I got in both cases.

Try these things

`nrfjprog --eraseall`

`west flash --recover`

Paste outputs
