cannot open system_nrf52_approtect.h

[Taylor]

Hi,

When I build ble_app_uart->PCA10040->S132->arm_no_packs in SDK17.0.2,there logging an error:  #5: cannot open source input file "system_nrf52_approtect.h": No such file or directory.

Should I replace other system_nrf52.c file in arm_no_packs->RTE->Device->nRF52832_xxAA->system_nrf52.c? Because there is no system_nrf52_approtect.h in modules->nrfx->mdk->system_nrf52.c.

Hi,

I have the sam problem. when I use SDK17.0.2, nRF_DeviceFamilyPack 8.35.0 will be used and there's no system_nrf52_approtect.h. But when you use SDK 17.1.0, nRF_DeviceFamilyPack 8.40.3 will be used and there's no problem.

Hi,

This is caused by a mismatch of versions in combination with the added support for latest revision nRF52 devices with improved AP protect scheme. You can fix this by simply commenting out line 32 and 272 in system_nrf52.c.

Note that migrating to SDK 17.1.0 or at least MDK 8.40.3 (included in nRF_DeviceFamilyPack 8.40.3) is needed if you are considering using  your firmware with the latest revision (revision 3 of nRF52832).

Thanks for your reply.

Can I replace the system_nrf52.c file with modules->nrfx->mdk->system_nrf52.c?

That should be OK, yes
