Hello,
I tried to read and write the OTP region in UICR of nRF5340 with nrfutil, but got the following output:
$ nrfutil.exe device x-write --address 0x00FF8100 --value 0x11aabbcc --core Application x Failed to write data to 48315XXXX, [jlink] Memory write is not implemented for this device Error: One or more memory write tasks failed: * 48315XXXX: [jlink] Memory write is not implemented for this device, code: NotSupported $ nrfutil.exe device x-read --address 0x00FF8100 --core Application Error: Failed to memrd read one or more devices: * 48315XXXX: [jlink] Memory read is not implemented for this device, code: NotSupported
Any Ideas, what could be the issue here? Does nrfutil not support reading uicr from different cores right now? Had no problems doing this with nrfjprog.
Thanks a lot!
