  • Main changes in this version

    For a full overview of all changes, please read the release notes located in the installation directory.

    • 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.
