Is possible to install debian 8 from this startpoint or do I miss something? thank you in advance. Marco

Marco,

Yes it is possible to boot Debian jessie on USB with your u-boot. See the rootfs release thread.

However, your u-boot was not restored correctly. Your envs are not for the Pogo E02. It is for Pogo V4. Also, the envs are for an older u-boot version than the latest u-boot.

Please post the whole serial console log (from the banner until you interrupt it, and printenv). I need to see u-boot version to help you further.

I used this tutorial to recover uboot after a bad flash. I installed this uboot.2015.10-tld-1.pogo_e02.bodhi.tar

I tried to follow this guide but i'm stuck at point 3.
I formatted a usb pendrive in ext3 through my linux pc, created a boot folder in the root of the pendrive, extracted linux-4.8.0-kirkwood-tld-1-bodhi.tar.bz2. But I think I miss something..

Marco,

> Pogo E02

Your envs are not correct, so we will need to put the envs in the /boot folder of the rootfs to recover. Your installed u-boot is relative new. So that will make it easier.

This is not correct. You dont need to install the kernel. The released rootfs is ready to be used. You can upgrade the kernel after booting into Debian.

=============


Here is what you need to do:

1. Create the Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2 rootfs on USB using the instruction in the rootfs release thread. See section:

Quote

Updated 20 Feb 2016:

This Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2 is to keep in sync with kernel Linux-4.4.0-kirkwood-tld-1.

2. Download the script uboot.2016.05-tld-1.environment.scr that I've attached to this post (this is the default envs text in script format).

3. Mount the USB rootfs on another Linux box (and assuming it is mounted as /media/sdb1), copy the script to /boot folder

cp -a uboot.2016.05-tld-1.environment.scr /media/sdb1/boot/
sync

4. Plug this rootfs to the Pogo E02 and power up, interrupt serial console and execute commands:

usb start
ext2load usb 0:1 0x800000 /boot/uboot.2016.05-tld-1.environment.scr
source 0x800000

and then boot

boot

Hi bodhi I followed your suggestions. I can now boot the rootfs and I'm trying to sync with kernel Linux-4.4.0-kirkwood-tld-1
following steps updated on 30 June 2015 in this thread.
but I'm stuck at point 3.

Quote
3. And install it with dpkg. If you encounter error with flash-kernel when running dpkg, then remove flash-kernel first to avoid potential problem (It is much better to generate uImage and uInitrd manually anyway):

I cannot execute dpkg commands neither from my ubuntu box (different architecture error) nor from from the rootfs prompt (because I cannot see /boot folder)

I find these folder when I boot:

(initramfs) ls
bin      dev      init     proc     run      scripts  tmp
conf     etc      lib      root     sbin     sys      var

What am I missing?

ueghio,

You have not booted into Debian. When you see the initramfs prompt, it means that the rootfs has not been mounted successfully, so the kernel exited and you are in the temporary rootfs (i.e. the one provided by initramfs).

I think your rootfs creation was not done properly. During rootfs creation, you must follow the instruction very closely (thing like being root user, and label the partition rootfs are important). If you missed any step, the rootfs will not work. dpkg is not needed at all during rootfs creation (only use this to upgrade the kernel after you have booted into Debian successfully with kernel 4.4 inside the rootfs).

Please post the entire bootlog (from the u-boot banner until the initrmfs prompt). And if you'd like me to check, post the entire log of what you did during rootfs creation here.

Thank you bodhi, i apologize for being a newbe..i missed the step of label rootfs. Now I can boot into debian

root@debian:~# uname -a
Linux debian 4.4.0-kirkwood-tld-1 #1 PREEMPT Mon Jan 25 20:35:24 PST 2016 armv5tel GNU/Linux
root@debian:~# cat /etc/debian_version
8.3

When I booted after this step

usb start
ext2load usb 0:1 0x800000 /boot/uboot.2016.05-tld-1.environment.scr
source 0x800000

I encountered a kernel panic but now I think everything should be right.
In your opinion would be convenient to install the last
u-boot and kernel image?



Edited 3 time(s). Last edit at 02/22/2017 01:24AM by ueghio.

ueghio,

You need to boot using these commands in serial console for a few times

usb start
ext2load usb 0:1 0x800000 /boot/uboot.2016.05-tld-1.environment.scr
source 0x800000

to confirm that you can boot Debian:

root@debian:~# uname -a
Linux debian 4.4.0-kirkwood-tld-1 #1 PREEMPT Mon Jan 25 20:35:24 PST 2016 armv5tel GNU/Linux

And then at the next boot, save it permanently

usb start
ext2load usb 0:1 0x800000 /boot/uboot.2016.05-tld-1.environment.scr
source 0x800000
saveenv

and

boot

After that, shudown the box, backup your rootfs using this instruction (remember you have to be root user for this to work):
http://forum.doozan.com/read.php?2,12096,24034#msg-24034

And the proceed to install the latest kernel.

ueghio,

You need to post the entire serial boot log doing this:

usb start
ext2load usb 0:1 0x800000 /boot/uboot.2016.05-tld-1.environment.scr
source 0x800000
printenv

and then

boot

Without the entire log, I can only guess the problem, but will not able to determine for sure what it was.

-------

However, from the partial log above, I can tell that your rootfs was not created correctly. You should not do step 4.

4. Create uImage with embedded DTB for booting with older u-boots (2012 or earlier). Skip this step if you have installed the latest U-Boot for Kirkwood (or are installing this u-boot at the same time).

Bodhi, your assumption was right. I didn't skip point 4. Now booting process ends without errors and I can log in. I'm going to update the kernel in the next days. Tank you for your help. Marco
