Linux/TDA2P-ACD: Linux hang while coping root file system into Emmc Partition

Linux/TDA2P-ACD: ubi file system on eMMC Partition

Tool/software: Linux

Hi,

we are working on custom board TDA2Px. We are using psdk 3.4 for booing the board, We have successfully boot the eMMC with two partitions named as FAT (SPL and uboot) and ext4 (rootfs).

As per the our requirement for eMMC, we need to partition the eMMC into ubi type for root fs. As per our analysis  and ubi documentation says that ubi fs not supported for eMMC, it is supported on raw NAND.

Please refer the shared link below for better understanding.

But as per the Vishal Mahaveer said (TI Member) "In the partition table, you don't mention the type.
As long as you flash the image type you need to the partition and the component mounting the partition knows how to mount it, ubifs should work."

Please confirm and if possible then please let me know the steps how can we partition eMMC with the ubi fs ?.

Regards,

Swapnil Balpande

    Hi Swapnil,

    I may be wrong about ubifs. As the link mentions ubifs is not for eMMC.

    My comment was generic that, when you define the partition table in u-boot, you don't mention the type of partition (ext2, ext3, ext4, raw, etc..)
    You flash the right image type to the partition and the module mounting the partition should match the image flashed. Typically this is done by fstab entries in Linux.

    Regards,
    Vishal
