Good evening everyone
We are working to rotate BAT / NAND in a Cubieboard2 with Samsung NAND 316 K9GBG08U0A SCB0
Below show the whole process I am following:

Trying to boot from NAND
### ERROR ### Please RESET the board ###
Someone would have a repository there date with all applied u-boot patch
where can I test there?
Boris, Hans has a repository where could this auditioning
if you could pass the test for the purpose cubieboard2
I saw several reports of people who managed to boot but not with cubieboard2
Talves is forgetting something or even going wrong parameters so would like a reliable repository of for NAND / BAT Samsung Sun7i
Thank you very much in advance!
