Hi.
I use buildroot-2014.05.tar.gz to build Linux version 3.14.4 for i386 architecture.
I am able to boot up the code using Grub2 on my PC.
That is the case if I use initrd /boot/rootfs.cpio.
My grub.cfg is as follow.
set default="0"
set timeout="0"
menuentry "any name" {
????????? Linux /boot/bzImage root=/dev/sda console=tty1
????????? initrd /boot/rootfs.cpio
????????? }
But the data is not persistent, anything that I save will be gone after reboot.
I am looking for method to make the data persistent (no?ram file system).
I try to boot up the code without using rootfs.cpio as follow.
The code won't boot up.
set default="0"
set timeout="0"
menuentry "any name" {
????????? Linux /boot/bzImage root=/dev/sda2 noinitrd?console=tty1
????????? }
For your info, I use pendrive for this.
And the bzImage and rootfs.cpio is located in partition 1 boot folder.
File system is located in partition 2.
Hope I can get some?help here.
Thank you very much. :)

If you're using a root filesystem in the second partition, then there's
no point in keeping the rootfs.cpio file in the fist partition.

Yes, but please provide more details, like what happens when you try to
boot, and how you create your second partition exactly. With the
informations you provided, there is just no way for us to help you as
you didn't provide enough details.
Best regards,
Thomas

Hi. Thanks for replying.
I build the code with settings below.
menuconfig -> Filesystem images -> ext4.
menuconfig -> Filesystem images -> tar the root filesystem.
menuconfig -> System configuration -> Init system with Busybox (default).
menuconfig -> Toolchain -> Buildroot toolchain (default).
menuconfig -> Toolchain -> C library uClibc (default).
Steps to build the partitions.
1) I use sudo dd if=/dev/zero bs=1M count=1 of=/dev/sdb to wipe out the original partition in my pendrive.
2) sudo fdisk -l will shows /dev/sdb doesn't contain
a valid partition table.
3) To recreate the partition, I use sudo fdisk /dev/sdb.
4) I enter n for new partition, p for primary, label partition as 1, default minimum for first sector, 5000000 for last sector.
5) Then enter n again to create second partition, p for primary, label partition as 2, 5000001 for first sector, default maximum for last sector.
6) Then enter w to write the partition table.
7) Power cycle the pendrive.
8) I format the partitions using sudo mkfs.ext4 /dev/sdb1 and sudo mkfs.ext4 /dev/sdb2.
9) I sudo mount /dev/sdb1 /home/leecgy/temp1 and sudo chmod a+rw /home/leecgy/temp1 to enable writing to partition 1.
10) Then sudo mount /dev/sdb2 /home/leecgy/temp2 and sudo chmod a+rw /home/leecgy/temp2 to enable writing to partition 2.
11) I right click and create new folder called boot in partition 1, then right click and copy paste the bzImage into boot folder.
12) Then right click and create new folder
called grub in boot folder, then right click and copy paste the grub.cfg into grub folder.
13) I sudo grub-install --boot-directory=/home/leecgy/temp1/boot /dev/sdb to install grub.
14) I right click and extract the rootfs.tar, then right click and copy paste the contents inside rootfs into partition 2.
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 let me know if you need more info.
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

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.

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.

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

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

This is wrong. Don't believe what you read on "the Internet". An initrd
is an *optional* mechanism. Basically, you have several choices:
1/ The kernel directly mounts the real root filesystem, as indicated
by the root= kernel parameter. There is no initrd involved
whatsoever.
2/ There is an initrd, but it never switches to another root
filesystem. This is sometimes used for very small systems: it allows
the entire filesystem (contained in the initrd) to be loaded in RAM
by the bootloader. I typically use this when I do kernel
development: this way the root filesystem (contained in the initrd)
can be used by the kernel without the need of any network or
storage driver.
3/ There is an initrd, which does a part of the system initialization,
and then switches to the real root filesystem. This is what is used
by most desktop/server Linux distributions.

Indeed.
Please pass "rootwait" in your kernel parameters. It tells the kernel
to wait until the root device appears: USB devices are detected
asynchronously, and sometimes the kernel may try to mount the root
filesystem before the USB devices have been detected.
If that still doesn't work, it means that your kernel configuration is
wrong and lacks some device drivers.

Hi, Thomas.
It works.
With "rootwait", it can boot with no initrd.
Thank you very much. :)
