Disable readback protection on an nRF9160

MJD093

Hi,

I have somehow activated readback protection on a custom nRF9160 device and I can't seem to recover it via the usual method with nrfjprog.

Running "nrfjprog --recover" gives:

nrfjprog --recover
ERROR: nrfjprog could not identify the target device. This may be due to an 
ERROR: invalid family argument, a problem with your device, or nrfjprog may
ERROR: not yet support your device.
ERROR: Please check the family argument passed, or upgrade nrfjprog to a more
ERROR: recent version.

Trying with -f NRF91 gives:

nrfjprog --recover -f NRF91
Recovering device. This operation might take 30s.
ERROR: Recover failed. Please make sure that the correct device family is given
ERROR: and try again.

Am I missing something here in order to get recovery to work?

    Hi Michael,

    Which version of nrfjprog do you have?
    open cmd --> 'nrfjprog -v'



    Please make sure you are running version 10.11.1

    Release notes in version 10.11.1

    Update bundled Segger installers and tar balls to v6.86f.

Updated doc string for NRFJPROG_erase_all to make the note about NVM block 
protection more clear.

Add function NRFJPROG_is_eraseprotect_enabled(). In devices that does not 
support erase protection (nrf51, nrf52), this function returns false.

If erase protection is enabled, erase functions will now return 
NOT_AVAILABLE_BECAUSE_PROTECTION if the target operation is not possible.

NRFJPROG_recover() can now disable erase protection if no readback protection
is enabled.

Fixed issue where in nRF53 devices, NRFJPROG_readback_protect(SECURE) did not 
enable secure ap protection.

Fixed issue where in devices with trustzone, nrfjprog could select NVMC_NS for 
erase operations, causing the erase operation to fail silently.

Fixed issue there if SECURE readbackprotection was enabled, NRFJPROG_read(), 
NRFJPROG_read_u32(), NRFJPROG_write(), and NRFJPROG_write_u32() would fail with 
NOT_AVAILABLE_BECAUSE_PROTECTION even though the operation was possible.


    Best regards,
    Martin L.

    Hi Martin,

    I am using the latest JLink and nrfjprog versions as you showed above:

    nrfjprog --version
nrfjprog version: 10.11.1 
JLinkARM.dll version: 6.86f

    I updated my tools while trying to unlock the nRF91 but as shown in the original post, even with the latest tools the device will not remove it's protections

    Could you run the commands with the '--log' at the end to gather the debug log.
    e.g. "nrfjprog --recover --log"

    and then share the log in this case?

    It looks like it fixed itself with a power on reset? The battery died overnight, charging the unit and trying 'nrfjprog -e' seems to have worked. JLinkExe is not showing any issues now connection to the CORTEX-M33 as it was yesterday?

    Would a power on reset really remove readback protection?

    Hi Michael,

    I am glad to hear that you got it to work again.

    Most likely the device was in some kind of weird state and the power-on reset fixed it.
    (no, a power on reset will not remove readback protection when that is enabled)
