kernel 2.6.35 on imx233: boot problem

Question asked by Alberto Biancalana on Mar 29, 2013
Latest reply on Oct 23, 2013 by Alberto Biancalana

Hi, i'm trying to move from imx233 2.6.31 environment to 2.6.35 kernel by using ltib for mx28 configured for imx233.

Just trying to launch linux on my custom board, where the 2.6.31 kernel runs since some months.

Now on ltib I've set ub a basic 2.6.35 kernel for mx233 to load on the card and I've a bad problem as you can see at the end of the attached log.

 

I'm using the same boot command I used for 2.6.31:

     noinitrd console=ttyAM0,115200 ubi.mtd=1 root=ubi0:rootfs0 rootfstype=ubifs rw ip=none gpmi

which worked perfectly with 2.6.31 kernel and now I'm not able to understand what's happening.

The boot log for 2.6.3.1 is almost identical, no problem to see the NAND flash, so the problem is ubi, pheraps.

 

Could anyone give me indications about this problem?

 

Thanks

 

Alberto
