Problems with Android from NAND.

[teamteck]

After doing some tests with linux I'd try android on NAND.
so I removed the Debian sd card and I restarted. I also tried the recovery but nothing happens.


the display will light up at startup but then stays off. From serial cable for debugging I get nothing.
I waited for several minutes.

Before I use linux,  I could run Android from NAND correctly


What happened now?


Thanks.
