NRF5340 Not Recognized by nrfprog

[Deus Matei [EMERSON]]

Everything was working fine but suddenly we're not able to program RNF5340 device with J-Link Plus debugger. We tried also recovering the device but we get an error that device type is not recognized. Output from nrfjprog bellow.

 

Also using NRF programmer we see following error:

Our HW design follows NRF5340DK design. In the past we were able to recover the device using nrfjprog recover oprtions but not anymore.

Hi Deus,

Which 5340 device are you using? Is it a custom board or our DK?

Could you try nrfjprog --recover --family nRF53 --coprocessor CP_NETWORK ?

Best Regards,

Priyanka

Hi It happened with a custom board using a Jlink Plus debugger. Currently debugging it's working fine. There are issues from time to time but apparently issues are diapering without doing anything special.

When this issue is present also recover commands are failing.
