Hi All.
I'm newbie on OMAP-L138 Platform. I have some questions.
i'm develop Linux OS for OMAP-138 Device. so, i'm using OMAP-L138 LCDK.
now i have preblem nand file-system download and it's working.
Kindly guide me.
[Environment]
-Ubuntu 14.04 64bit
-CCSv6
-mcsdk 1_01_00_02 , Arago tool chains
[ Question ]
1. How make file-system file? (JFFS2, UBIFS) -> my ways are corrected?
-> UBIFS or JFFS2 file systems are same problem (kernel panic)
2. kenel panic's reason. why my file-system incorrect behavior?
-> need modify sources? (uboot , kernel, file-system or others)
-> or i missed change point?
3. newest "OMAP-L138 Reference guide" is exist? or see other platform's guide? (ex .. AM18XX....)
[DESCRIPTION]
I'm using Default SDK's Source (u-boot, Kernel, file-system)
changes are kernel config
- MMC/SD Use -> Disable
- MTD Settings Enable (for JFFS2 , UBIFS)
other's are not changed ( Default source )
Make file-system and Download (using NFS)

-Make Filesystem

- u-boot / kernel source is not modify. (only changes are kernel config use Menu-Config)
- make file-systems are as follows.
