I suggest that you'd better ask Merrii to give you the parameters. Otherwise you could first try to dd the boot0 to a clean sd card from 8kB and see if there is any print out from the serial port (just set the serial port of you computer to 115200n8), if not work, move up 4kB every trial until you see the right output. Do the seem thing to uboot begin from the end of boot0, until you find something meaningful. Plus good luck.
