Hi all,
I have recently upgraded my tools to SDK 5.2 and JLink V4.84f, and started using nRF51822 G0 chips. The issue I have is with recovering the part in the Studio 1.16.1. With reference to below, you can see that nrfjprog -e will erase the chip OK but nrfjprog --recover gives an error (Could not Start CPU Core) when at the Applying pin reset. step.
Maybe I need to roll back the JLink drivers? I've tried all the tips form other posts but no joy.
From my command prompt:
C:\Users\S3>nrfjprog -e
Applying system reset.
Disabling flash write and erase protection mechanism.
Erasing all flash (code region 0, code region 1 and UICR).

C:\Users\S3>nrfjprog --recover
