I tried the following command but it's still not working:
setenv bootargs "rootwait console=tty0 console=ttySIF0 root=/dev/mmcblk0p2 rw"
load mmc 0:1 ${fileaddr} fitImage.fit; bootm ${fileaddr}
Hi, adding offical documentation/support for this will happen soon, but in the meantime: I am assuming that you are using the aloe vera kit, since you are calling the console "ttySIF0". In that case, you will need to run an additional command to transfer the rootfs to the board:
sudo make DISK=/dev/sdX DEVKIT=mpfs format-rootfs-image
once that is loaded onto the sdcard, chroot should work correctly.
Hello, Thanks for your reply. I tried doing that but with a Debian rootfs and chroot is not working, I cannot access or edit any files inside the chroot.
Thanks.
Interesting, I'll give a debian root fs a try and see how it goes for me and let you know.

Thanks! Please try and give me instructions how to make it work if it works.
The error I'm getting is file not found when opening for a example /etc/resolv.conf in chroot with nano editor.
I don't have a large enough SD card to hand to test with a debian rootfs a try yet, but I did try today with the one built via buildroot, which i transferred to the sd card with: sudo make DISK=/dev/sdX DEVKIT=mpfs format-rootfs-image
I was able to mount it & chroot into it with no problems. I will try the debian rootfs once I get a larger SD card.

Okay thank you, can you tell me how you chroot into the rootfs? You just used one command the chroot command with the rootfs folder? Or there's more commands to run to chroot correctly?
i did:
mount /dev/mmcblk0p2 /mnt
chroot /mnt /bin/bash
Okay I tried with a different Debian rootfs and it's working fine. How can I make it boot directly to Debian rootfs instead of buildroot?
Running xorg server fails because its inside chroot. Can you advise how to get xorg to work with a Debian rootfs in chroot? Or is there a way to make it boot in a real environment, not chroot?
Easiest way to do this is to change the uboot script. First check that the bootargs in the second line of the linux defconfig contain the correct the correct partition should be "root=/dev/mmcblk0p3" with the current release although this will change in the next release and is different for the icicle kit.
If you change the contents of conf/mpfs/uEnv_s-mode.txt
to:
boot3=load mmc 0:1 ${fileaddr} fitImage.fit; bootm start 0x90000000; bootm 0x90000000 - 0x82200000
it should boot using the rootfs on the SD card not the initramfs built by buildroot
Thanks alot for your help. It worked. I booted to Linux directly instead of buildroot. 👍🙂
Hello, I want to boot from the 2nd partition on the mmcblk0p2 device. Chroot is not working. How can I edit uEnv.txt to boot from the 2nd partition?
Thanks.
