iMX6ULL Custom Board not booting on Hardknott

[lmainardi]

Hi all,

I have a custom iMX6ULL board, developed from the 14x14 evk, which features 256MB of RAM (instead of 512) and boots from the SD card.

Until now, on Rocko (ver. U-Boot 2017.03-imx_v2017.03_4.9.88_2.0.0 ) it booted flawlessly; Trying to migrate on Harknott, the compilation is successfull but it seems like the board can't load the kernel.

Since the logs say that's a syntax error, I've tried to disable every .bbappend file I've generated, but it didn't help.

Logs attached:
