writing into UICR OTP of APP core with nrfprog fails on nrf5340

Robert

I try to write data into the OTP section of the APP core with the following command line:

nrfjprog.exe -f nrf53 --program 'OTP.ihex'

ouput:

[ #################### ] 0.116s | Program file - Done programming
WARNING: A programming operation has been performed without --verify.
WARNING: Programming can fail without error.

If I use Ozone to display the written content in a memory window I can see the data written to the OTP memory. But if I perform a power cycle the OTP section is empty again.

I also tried to use the following command for tests: nrfjprog -f nrf53 --memwr 0x00FF8100 --val 0x7E75

the same problem here: cells are empty after power cycle.

Initially I tried to use JFlash without success. This resulted in an error message even if I enable the OTP bank and disable all others

Any Hints how I can write the OTP section permanently?

    These errors are indicating a problem with nrfjprog and the jlink version.

    If you want to use nrfjprog, and not the newer "nrfutil device", I would recommend that you use the recommended jlink version that is bundled here:

    https://www.nordicsemi.com/Products/Development-tools/nRF-Command-Line-Tools/Download?lang=en#infotabs

    I also tried to use the following command for tests: nrfjprog -f nrf53 --memwr 0x00FF8100 --val 0x7E75

    the same problem here: cells are empty after power cycle.

    After installing the recommended jlink version, could you try to re-try this sequence?

    You can use "nrfjprog --memrd 0x00FF8100" to readback after a reset/power cycle.

     

    Kind regards,

    Håkon
