nrfjprog --verify fails when programming just after a recover (nrf5340)

ludelle

Hello,

To create an automated flash tool, we want to split flashing steps between erase and program steps. 

When performing a recover before flash, program verify fails.

nrfjprog --recover -f NRF53 --coprocessor CP_NETWORK
nrfjprog --program build/zephyr/GENERATED_CP_NETWORK_merged_domains.hex --verify -f NRF53 --coprocessor CP_NETWORK

When using single-line, it work fine. 

nrfjprog --program build/zephyr/GENERATED_CP_NETWORK_merged_domains.hex --recover --verify -f NRF53 --coprocessor CP_NETWORK

I use latest version of nrfjprog (10.23.2). Below is a two steps description of the problem

1) recover both CP_APPLICATION and CP_NETWORK

nrfjprog --recover -f NRF53 --coprocessor CP_APPLICATION
Recovering device. This operation might take 30s.
Erasing user code and UICR flash areas.
Writing image to disable ap protect.
nrfjprog --recover -f NRF53 --coprocessor CP_NETWORK
Recovering device. This operation might take 30s.
Erasing user code and UICR flash areas.
Writing image to disable ap protect.

2) program with --verify the CP_NETWORK (without --recover)

Programmation failed on verify:
