Hailo15h yocto issues

Hi!
I’m trying to make a custom yocto image, and for some reason the image stops booting after (i think) some size threshold is reached. Eiiter if I add dev packages or set the fixed partition size. Could you help with that?

Could you also explain difference between uboot flashing modes: wic and partition.
The partition mode seems to sometimes work, but wic mode just says that no partitions are dound after flashing and I have to start from the uboot itb file again.

Also! I wanted to maybe re-flash uboot to make sure it’s up-to-date, but I can’t find the hailo15_board_tools package mentioned in the manual anywhere.
