BLE BAS Central compiles as a secure application

Thanks, the solution was to set CONFIG_NCS_SAMPLES_DEFAULTS=n and CONFIG_DK_LIBRARY=n.

Hi,

[quote user="StefanoN"]Recovering the device erases the flash, so I can't debug the code because its being erased.[/quote]

I mean recovering and then programming to debug. The CONFIG_NRF_APPROTECT_USE_UICR is default enabled in NCS, so it will look up UICR.APPROTECT value.

You could read UICR.APPROTECT(0x10001208) to check if it's enabled by nrfjprog --memrd 0x10001208.

Recovering the device erases the flash, so I can't debug the code because its being erased.

Reading this I see that HW access port protection is enabled by "writing Enabled to UICR.APPROTECT and performing a reset"

I wonder where this is done because I don't see it in the main.c of the BLE BAS Sample code.

Hi,

nRF52833 doesn't have the non-secure area so you can build for nRF52833 without ns.

Run recover (nrfjprog --recover) before programming, it would unlock/unsecure the device.
