Trouble programming nrf5340dk

[Hongfeng]

I am following the guide on this page: https://github.com/project-chip/connectedhomeip/tree/master/examples/lock-app/nrfconnect

I can build the firmware, but having trouble to program the nRF5340DK. 

west flash --recover

ERROR: The --family option given with the command (or the default from nrfjprog.ini) does not match the device connected.

Hi Hongfeng! 

Thats odd. Do you know what chip version are you using? 

And what does it output when you run:

nrfjprog --recover --coprocessor CP_NETWORK -f NRF53
nrfjprog --recover -f NRF53

Best regards,

Elfving

nrfjprog --recover --coprocessor CP_NETWORK -f NRF53

ERROR: The --family option given with the command (or the default from nrfjprog.ini) does not match the device connected.

nrfjprog --recover -f NRF53 --log

ERROR: [  nRF53] - Debug probe is not connected to an NRF53 series device.

ERROR: The --family option given with the command (or the default from nrfjprog.ini) does not match the device connected.

The sticker on the board:

PCA10095

0.11.0

2020.51

960138681

FYI, I was able to program nRF52840 Dongle on the same laptop setup

Could you give me that logfile that was generated?

And could you try "nrfjprog --eraseall", as well as checking the Programmer in the nRF Connect App?

Best regards,

Elfving

[Hongfeng]

nrfjprog --eraseall --log

ERROR: [  nRFXX] - Device does not have an ARM debug port.

Thanks for the help!

It got even worse. Now I can't even detect the usb serial port.I start to suspect the board is bad. How can I get a replacement? I bought it from DigiKey.
