Hello,
I've an issue that I can't find clear instructions for the nRF5340 serial recovery for the network core.
Being able to update both cores from the bootloader level is crucial for my application, however, I feel like there's a lack of support regarding this area.
I've explored several threads here mentioning the same problem over several nRF Connect SDK versions, but most of them are out-of-date, and none of them reached a conclusion on whether it's possible or not.
Also, as mentioned in one of those tickets, it's mentioned that this Bluetooth: Peripheral UART sample project supports the Net-Core serial recovery by adding some extra configurations without mentioning how this can be tested or verified.
Also, the course for DFU from DevAcademy explicitly mentions that serial recovery for the net-core isn't covered.
Can you help with that?
FYI, updating the 2 cores over the serial port or using FOTA from the application works fine, but this requires the application to continue supporting this feature between subsequent versions and doesn't guard against application failures.
Thanks,
Ahmed
