Hello Support Team,
The customer reported that the nRF54LV10A-QFAACA seems to automatically enable APPROTECT. The customer assembled their own boards with the nRF54LV10A-QFAACA, and after programming and running the original ncs v3.3.0 peripheral_uart example, a subsequent attempt to reprogram triggers a 'readback protection enabled' warning. Only an erase or recover operation allows reprogramming. However, customer confirmed that when programming the same peripheral_uart example on the nRF54LV10 DK board, reprogramming can be done without erasing first.
The customer's own board uses the nRF54LV10A-QFAACA, and the development kit board also uses the nRF54LV10A-QFAAAC. They are both engineering sample chips, just with different revisions.
Please help clarify this issue.
Best Regards,
Tony
