Hi Jhon, Thanks for your suggestion. I tried: dd if=boot0_sdcard_sun9iw1p1.bin of=/dev/mmcblk0 bs=1024 seek=X

If anyone else have a suggestion - I'll be grateful On Thursday, September 4, 2014 3:01:34 AM UTC+2, Jhon Yi wrote: > > 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.
