Hi.
Below is the teraterm log for noinitrd.
I use single partition for this, sda1.
Seems like the device driver is not ready yet to detect sda1.
You have any workaround for this?
Else I just stick to my method in previous email.
Thanks.

[ 3.315412] [drm] Enabling RC6 states: RC6 on, RC6p on, RC6pp off

Hi, friend.
I took a look at the /boot/grub/grub.cfg from my PC, it also need initrd to boot up.
I also saw some article from internet saying initrd is a must and the kernel init process is the one that responsible to switch from ram file system to real file system.
Anyway, if I can get a USB to RS232 cable next week I can try to capture the log and see.
Currently I have a workaround to change root to real file system during kernel init.
Below is the code I use.
I put the code in /etc/init.d as startup.sh and create S99startup by refering to other scripts in /etc/init.d to call out my startup.sh .
#!/bin/busybox sh
# Wait for sda detected
sleep 5
# Mount the root filesystem.
mkdir /mnt/root
mount -t ext4 /dev/sda1 /mnt/root
mount -o bind /dev /mnt/root/dev
mount -o bind /proc /mnt/root/proc
# Boot the real thing.
chroot /mnt/root /linuxrc
Thanks.

You may want to follow the instructions available in the help text of
the Grub 2 option, which have been tested.

Make sure you extract things as root:
sudo tar -C /home/leecgy/temp2 -xf output/images/rootfs.tar
> When trying to boot up, the code dump a lot of error and stuck. I cannot shift+page up to see the top of the error.
Please give the
errors that you see. For now, we still have no idea
whether it's a bootloader problem, a kernel problem, or a root
filesystem problem. Without the boot log, there's not much we can do.
Best regards,
Thomas
