Hello,
could you try running "setenv console tty0; saveenv" at the u-boot prompt
and then retry booting the system with boot.scr? The boot script in Jessie
passes the u-boot console variable to the kernel, and that points to the
serial console by default. Changing it to the framebuffer console might
result in further kernel output in your case.
Regards,
Karsten
