Hi,

Could you tell me more about your hardware and setup? Is it a regular nRF52800DK or is it a custom board?

Could you supply me with the overlay files if any?

Kind regards,
Andreas

I am aware of the issue reported at https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/config_and_build/bootloaders_and_dfu/bootloader_external_flash.html#troubleshooting.

I have applied the changes but am still seeing the same initial error from mcuboot:

E: Device id 00 00 00 does not match config 1f 45 08

Hi,

This issue looks like the first issue reported at https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/config_and_build/bootloaders_and_dfu/bootloader_external_flash.html#troubleshooting

What I suspect is that you see the changes in how image management, among other things, has been included within configurations rather than being required as code in your project.

For instance as shown here in this repository written by a colleague of mine containing multiple minimal bootloader samples:

Note the difference in between main.c from v2.2.0 and v2.3.0 tags of the mcuboot_smp_ble sample (the complete changelog can be seen here).

Could you investigate the differences and see if applying the changes allows you to migrate your project from v2.2.0 to v2.3.0? For v2.4.0 there might be other changes that the repository I mention does not consider as the samples here are only tested for v2.2.0 and v2.3.0 of NCS

Kind regards,
Andreas
