AV700 is already in tdt git, why you don´t use this?
as told above: use the git kernel.The bootloader find the kernel an decompresses it, but there's no output after that (I'm using putty for debuging), after a short moment The BOX reboots
furthermore: if you use the maxi-uboot from atevio titannit image then replace it with original fortis loader 2.23 or something like that
