Some progress to report:
I finally managed to flash the Optimus Board (OB) through the USB 3. It is
done using the PhoenixSuit and without installing the USB drivers (I found
all the necessary software at PCDuino8 site). Despite not managing to
install the usb driver on windows the PhoenixSuit
Thanks for your reply. I still could not get any progress; I tired
following the dd instruction you sent in the SDK page as well as two
methods described in pcduino8 page. I also got some stuff from Merrii (as
Jhon suggested). I published it in a newer post on this forum.

let them provide one bootable sdcard then dd out the content and
search for the position.

Hi Jhon,
Thanks for your suggestion. I tried:
dd if=boot0_sdcard_sun9iw1p1.bin of=/dev/mmcblk0 bs=1024 seek=X
where X = 0, 4, 8, ..

If anyone else have a suggestion - I'
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

the serial port of you computer to 115200n8), if not work, move up 4kB
every trial until you
