Failure to Program or Successfully Recover nrf5340dk

[samtday]

I am having issues programming my nrf5340dk through VSCode or the nrfjprog tools. I have tried as many remedies I can find on the DevZone but not of them seem to correct my issue.

When I attempt to flash my board, the terminal indicates JLink is not supported by current CPU + target interface combination and exits with error code: 33. I sometimes see the same error when issuing the 'nrfjprog --recover' command.

One DevZone ticket indicated I may have erased my JLink Chip and I tried the remedy suggested but was not able to see my nrf5340dk come up as a bootloader.

I will add some logs below. Any help is welcome, thank you in advance.

Hi,

Which version is the nRF5340DK? (Can be found on the white sticker)
