NRF52 DK cannot read device version

[SNL]

Hi, I am having some read protection issue on NRF52DK (pca10040) n52832_xxAA. The chip still works as programmed, but it seems having trouble communicating through JLINK.

I also checked P0.21 and it is high.

Attached Log is from --recover command.

Hi Abhijith, It is version 3.0.0
