Trouble building with mcuboot.

[dlewis]

Hi All,

I am getting build errors for a project. Project specifics below:
- nRF52832 (custom board)
- NCS v2.6.0
- Custom board files and other configuration files attached. pm_static.yaml included as text because file type not supported for upload.
1348.centurion_anywhere_button.zip00355.prj.conf3566.mcuboot.conf

### pm_static.yaml ###
partitions:
  mcuboot:
    address: 0x00000000
    size: 0x000C0000  # 48 KB
    region: flash_primary

Attached below is the build error(s) I am receiving. Any insight on what the issue may be would be greatly appreciated!

Below is a snippet of the build output errors. For some reason uploading as a txt or as code snippet is not working.

Hi David,

Have a look at DevAcademy Intermediate: Lesson 8 – Bootloaders and DFU/FOTA.
Then let me know if you still got the same questions.

Hi Sigurd,

I have followed that guide and have been working with a Nordic FAE for about a week on this, but they are out of office for the week and suggested I try and make more progress through a ticket while they are out.

Ah, that is good info.

In that case: What is your use-case for using pm_static.yml?

[dlewis]

I guess I should try and lay out as many of the steps/progress that we already went through before arriving at this ticket. 

It started with this ticket:
(+) Build Error Enabling CONFIG_BOOTLOADER_MCUBOOT and CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

In which the response did not appear to be relevant to the nrf52832 I am using. The Nordic FAE for my region noticed this and reached out to me by email and he started helping me from there.

Next the FAE had me comment out this portion from my custom board dts file

/*

&bprot {

   status = "disabled";

};

*/

This got us past the no fprotect build error. Then there was a build error from RAM overflow which I fixed by reducing memory usage in code.

Next we worked on adding the customer's existing private key file to use instead of the default nordic example one. For some reason this would not work using the prj.conf inclusion/cmakelists.txt inclusion methods. It did seem to work by adding a child_image folder and adding a mcuboot.conf file which is attached to this post for reference.

Now when building it would get past the previous issues but it would give a warning about not having a pm_static.yml file. This isn't confirmed to be the culprit of the errors shown as the basis for this ticket but we tried adding one anyways which didn't work, and also tried renaming and moving the partitions.yml to be the pm_static.yml. Both of those options removed the warning for not having a pm_static.yml but left us with the errors shown in the picture I attached in the first comment.
