[U-Boot] Problems loading Linux in A33

Hi,

I am trying to load linux in my Chinese device A33_ET_Q8. I have managed to create a bootable SD card to load the u-boot-sunxi-with-spl.bin file, the script.bin file, the boot.scr file and the sun8i-a33-q8-tablet.dtb file, but the system is getting stuck when the kernel is loading. I have attached a small video to check the problem.

I don't know the right configuration files for this tablet, so I am using the configuration files from other similar tablets.

Can someone give some advice to move forward with this problem?

Thanks a lot for the help!

Toni
