U-Boot sun7i NAND SPL - Cubieboard2 - MTD - Help

[Ezaul Zillmer]

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:

### 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!

Good afternoon

This repository with appropriate modifications rose mtd nand

Attached files if someone wants to test in your Cubieboard2

Thank Glaucio Klipel

I will put to the test in 15 cubieboard 2 all connected by cluster
