Hello everyone!
We've integrated the readout protection to our project, but unfortunately now we don't able to disable it.
The activation code presented below:
if ((NRF_UICR->APPROTECT & UICR_APPROTECT_PALL_Msk) == UICR_APPROTECT_PALL_Enabled)
{
return false;
}
NRF_NVMC->CONFIG = (NVMC_CONFIG_WEN_Wen << NVMC_CONFIG_WEN_Pos);
while (NRF_NVMC->READY == NVMC_READY_READY_Busy) {}
NRF_UICR->APPROTECT = UICR_APPROTECT_PALL_Enabled;
while (NRF_NVMC->READY == NVMC_READY_READY_Busy) {}
NRF_NVMC->CONFIG = (NVMC_CONFIG_WEN_Ren << NVMC_CONFIG_WEN_Pos);
while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
return true;
So we tried to use nrfjprog.exe --recover and did manipulations with jlinkcommander (access via control access port).
Each time everything looks like protection is disabled, but chip remains unflashable.
Could you help us please with this issue?
Many thanks in advance!
Best Regards
Ernst
