nrf5340 Audio Board programming and recovering fail

[Eric Dong]

python buildprog.py -c both -b debug -d both -p to FALSH the nrf5340 Audio DK (ncs2.2.0, JLink V7.84a ), it reports error.

Based on the error info, searched from the https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.2.0/nrf/applications/nrf5340_audio/README.html, I tried to recover the board from Readback protection,

But still fails, below is the log doing recover with "nrfjprog --recover --coprocessor CP_NETWORK". Please help me do a kind check?

Hi, 

Sorry for the delay in response. Marie is away being sick. Did you have any progress in this issue ? If not, then I can request one of my colleague who also have good insights with Audio to help with this.

[Eric Dong]

Anyway it has been worked again in my side (but I do not know exactly why). 

It's not a block point in my side now. We can close this
