Forced to recover the board each time I flash

Hey Abhijith,

I was discussing this issue with my colleague, and we figured it out! I also needed to add CONFIG_PROTECT=n to the mcuboot.config. As follows:

CONFIG_BOOT_MAX_IMG_SECTORS=512

CONFIG_NRF_APPROTECT_DISABLE=y

CONFIG_NRF_SECURE_APPROTECT_DISABLE=y

CONFIG_FPROTECT=n

This works now--thanks so much for pointing us in the right direction! You rock!

Now, I have another problem: I can't get RTT working. It used to work, but it's borked now. But to keep things straight, I'll open another ticket.

Thanks for all the support!

Alas, the problem still persists. I thought we had it fixed--I _think_ it flashed successfully twice without needing the recover step. And then I tried to connect the RTT up, and now, whether the RTT terminal is there or not, I need to recover each time again.

mcuboot.config has:

CONFIG_BOOT_MAX_IMG_SECTORS=512

CONFIG_NRF_APPROTECT_DISABLE=y

CONFIG_NRF_SECURE_APPROTECT_DISABLE=y

Hello,

There might have been a glitch preventing you from pasting the logs. You can always attach a file if pasting doesn't work.
However, I’ve now received the logs from our FAE (the one you're in touch with). From the logs, I can see that the application is using MCUboot.
So, please try disabling APPROTECT in the mcuboot.config file as well. This is because the bootloader initializes first after a reset and enables APPROTECT. As a result, the application won’t be able to reach a point where it can enable APPROTECT.
Let me know if this resolves the issue or if the problem persists.

Kind regards,
Abhijith

When I attempt to post the log, I get "An error occurred, please try again or contact your administrator." It's only about a hundred lines or so, so...?

It's a custom board.

I tried updating the nrfutil. It's now at v2.11.0.

Hello,

Is this a development kit or a custom board?

Can you try updating the nrfutil device and see if that resolves the issue? If not, I recommend sharing the complete log here so we can get more details. Are you trying this from VS Code?

Try running the command:
nrfutil upgrade device

Kind regards,
Abhijith
