Part Number: SK-TDA4VM


Hello,
SDK version: 0806
The following are uboot environment variables
Currently rootfs mounts mmc device 1 partition 2

I want to mount rootfs to mmc device 1. Should I directly change bootpart to 1:3 for partition 3?
args_mmc=run finduuid;setenv bootargs console=${console} ${optargs} root=PARTUUID=${uuid} rw rootfstype=${mmcrootfstype}
bootpart=1:2
finduuid=part uuid ${boot} ${bootpart} uuid

    Hi,

    Once you boot to kernel please check which partition has the rootfs. In the case of SD card we typically have root=/dev/mmcblk1p2 in the case of eMMC root=/dev/mmcblk0p1.
    So please check which mmcblk has your rootfs. The you can change:

    args_mmc=run finduuid;setenv bootargs console=${console} ${optargs} root=/dev/mmcblk1p2 rw rootfstype=${mmcrootfstype}
    bootpart=1:2
    Just change root to whatever maps to your rootfs partition.
