We are attempting to add various modules to our project. For simplicity we've reduced our system to a toy setup closely mimicking the structure of our project and are trying to run the tensorflow lite micro module.
The state of the code here: flite_main_proj compiles without error and runs the tflite hello world code on the nRF5340 dev kit board as expected.
Problems arise when we try to enable either the bootloader or bluetooth configs, currently commented out in the file proj.conf
CONFIG_BOOTLOADER_MCUBOOT=y CONFIG_BT=y
Either config produces the same errors on build. The following is from enabling MCUBOOT:

compilation terminated.Based on this discussion Setting CONFIG_BOOTLOADER_MCUBOOT=y in prj.config on custom board prevents code working an attempt was made to include the tf module in the child_image. We added the folder tflite_main_proj/app/child_image which includes a .conf duplicating our proj.conf. Unfortunately this has had no impact on our build and we are still seeing the same errors as before.
This may be a similar issues to (Missing Forum Thread)
Any advice is appreciated!
