Hi,
Thank you for your interest in NXP Semiconductor products,
You have to review the silicon version used, it seems that you are using A0 silicon revision and LF-6.12.49 supports B0 version.
After making sure you have the BSP version for your silicon version, it's not ensured that EVK images will boot your setup since it depends on EVK attributes (RAM chip and design, peripherals, package, etc.)
Regards
