Enabling JFFS2 support in sdk-am335x-evm-07.00.00.00

Hi Gokul,

Latest SDK's support ECC schemes as shown here: http://processors.wiki.ti.com/index.php/Linux_Core_NAND_User%27s_Guide#ECC_schemes_support The same wiki also has a section about JFFS2 support: http://processors.wiki.ti.com/index.php/Linux_Core_NAND_User%27s_Guide#JFFS2_support_on_NAND

Hi Biser,

I already read that document .Let me clarify my requirement .
I want to use both ubifs and fffs2 without modifying the kernel and uboot . For kernel it can be changed by modifying dtb or use different dtb for jffs2 and ubifs . I want to switch ecc scheme of u-boot from u-boot console so that without recompiling u-boot , so that i will be able to flash both jffs2 and ubifs .

Thanks and regards
Gokul CG

Hi Gokul CG,

I think what you want is possible, although the decision will not is standard. I've never done it, but when I saw the configuration of the kernel for both OS it can be do with one kernel. At least by:
processors.wiki.ti.com/.../AM335x_JFFS2_Support_Guide
processors.wiki.ti.com/.../UBIFS_Support
Now you need to create two different DT for each for your cases and from u-boot console you have to manually to load desire DT that you want. Also need to change the location to load the appropriate OS from command line for example:
console=ttyO0,115200n8 root=/dev/... ro rootfstype=ext4 rootwait
I think the idea is unusual, although difficult but possible.
