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.

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

These are the outputs I got in both cases.

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

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": 

PS C:\nordic\myapps\AppCore_RHS_SD_UI_v1B> .\nrfutil device recover --x-family nrf53

Can you show this error?

Marika Di Martino said:

his is the output when I use "nrfutil"

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

[Marika Di Martino]

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.

[dejans]

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
