Hello Everybody, hello Henrik,<br>
<br>
Thanks a lot for you response.<br>
Good news i can confirm and demonstrate F20 can boot from
SD/MMC !<br>
<br>
After reading your u-boot and linux source I build a small and<br>
minimalistic piece of code that blink all the pin can be used
by UART No<br>
clock setting, no watchdog reset, only GPIO init...<br>
I use mksunxiboot to add header and push it at 8K on the
SD/MMC and this<br>
work...yip ha !!!<br>
This is a real real good functionnality for this cheap cpu !<br>

the chips in the future.</div>

Now lets go to u-boot limbs...i'm trying to create the sun3i.h
file and<br>
learn how to use git ;)<br>
<br>
Bin<br>
<br>
PS: i dont get a firmware of my device, but i previously dump
all the<br>
nand part if needed<br>
