Hi,

I tried to find more information about configure u-boot for booting multiple UBI volumes on imx6, but seems to me that information is really sparse.

There was a proposal by Wolfgang Denk many years ago at https://elinux.org/Boot_U-Boot_from_UBI_volume, and I could not find anyone talked about it in ELC_2019_Presentations.

Apologize if I am wrong to seek solutions in u-boot mailing list.

If I have only one UBI volume rootfs in an partition /dev/mtd5, I can configure to boot the image from /dev/ubi0, but with following three UBI volumes, how should I configure u-boot to boot from the UBI volume configure file volume.conf? How to set up u-boot to start boot from the volume.conf?

I have three UBI volumes for UBIFS:

[kernel-volume] mode=ubi image=zImage vol_id=1 vol_size=10MiB vol_type=static vol_name=kernel

[rootfs-volume] mode=ubi image=rootfs_data vol_id=2 vol_size=110MiB vol_type=static vol_name=rootfs

[data-volume]

mode=ubi image=rootfs_data vol_id=3 vol_size=10MiB vol_type=dynamic vol_name=data vol_flags=autoresize

$ ubinize -o rootfs.img -p 130MiB -m 512 -s 256 volume.conf

Thank you.

Kind regards,
