Pogoplug e02 boot into rescue:~# after login, please help to reinstall debian

hi, I have a pogoplug e02 that had debian installed. But the flash drive was dead. I was thinking to reinstall debian by following the Pogoplug E02 Debian Linux Installation Guide. without usb attached, the Pogoplug E02 boot into "rescue:~# " after I type in root/root (user/password).
it's like this:

rescue:~#

As an linux newbie, I have been puzzled by "rescue:~# " for a long time. I was stuck and don't know what to do. Please help me out. BTW, I tried to ignore the "rescue:~# " thing and install the uboot. But I run into the following error message.

Please help me out, bodhi. I want to get out of "rescue:~# " and boot into "root:~# " after I input the user/password and re-install debian by following debian pogoplug installation guide.

Thanks

puzzlednewbie,

It means you have installed Jeff's rescue system successfully. The rescue system resides on NAND. Booting without Debiann on USB will go straight into that system. It is a Debian Lenny OS with Linux kernel 2.6.xx.

Now you can go ahead and install new u-boot and latest Debian on USB. Do install both while you're logging in Rescue system, at the Linux shell prompt 'rescue:~#"

Install U-Boot (uboot.2017.07-tld-1.pogo_e02.mtd0.kwb)

https://forum.doozan.com/read.php?3,12381

Install Debian rootfs (Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2)

https://forum.doozan.com/read.php?2,12096

So look at these 2 threads, and post whatever questions you have.

it looks like mission impossible to me. But I will try my best to work on it.

I run into problems on the first step. I am not able to download https://www.dropbox.com/s/vgbshmiq3o14btp/uboot.2017.07-tld-1.pogo_e02.bodhi.tar

I also tried other link format, wget still could not download.

because I could not use wget to download, so I tranfer the file to the flash drive to install.

I have followed your suggested instruction: But I have following issues:

rescue:/tmp# /usr/sbin/nandwrite -s 786432 /dev/mtd0 uboot.2016.05-tld-1.environment.img
uboot.2016.05-tld-1.environment.img: No such file or directory

I don't know what it means.

and also:

rescue:/tmp# /usr/sbin/nandwrite -s 786432 uboot.2017.07-tld-1.pogo_e02.mtd0.kwb
MEMGETINFO: Inappropriate ioctl for device

rescue:/tmp# /usr/sbin/nandwrite uboot.2017.07-tld-1.pogo_e02.mtd0.kwb
MEMGETINFO: Inappropriate ioctl for device

sorry if they look stupid. But as you know, I struggled to follow the guide by guessing.

here is the result of uBoot envs, is it correct? :

rescue:/tmp# fw_printenv
bootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}::off; bootm
bootdelay=5
baudrate=115200
arcNumber=3542
machid=dd6

I have no idea what uBoot envs result means. Bodhi, Did I do it right? Can I reboot? or before rebooting, I should first install debian kirkwoord as you have suggested? Thanks

I'm sure bodhi will be along to answer your other questions, but it appears your wget doesn't support HTTPS. Try:

wget http://www.dropbox.com/s/vgbshmiq3o14btp/uboot.2017.07-tld-1.pogo_e02.bodhi.tar

puzzlednewbie,

No, don't reboot.

When you install u-boot, you need to follow the instruction verbatim. As described, do Steps 1 to 11.

https://forum.doozan.com/read.php?3,12381

====

About the wget, try using the format

wget --no-check-certificate

Or just download the tarball to USB file, and bring it to the Pogo. You can also create the rootfs first

Quote

Install Debian rootfs (Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2)

https://forum.doozan.com/read.php?2,12096

And copy the u-boot tarball to it. That way when you are in Rescue system, you already got everyhting needed to proceed the installation

====

As you do u-boot installation Steps 1 to 11, if you see any error from the command, stop and post the entire log of what you did so far. Don't try to go to the next step.

Both of the following two wget methods don't work. Same error message.

puzzlednewbie,

As always, when you want me to double check what you did, please post the entire log of the session. Copy and paste everything on your terminal and post here.

The envs below look good, but unfinished. You did not follow exactly what the instruction said.

However, I cannot even say for certain whether you did it correctly without the entire log. Whether you have installed new u-boot correctly or installed the envs image correctly or not.

Not correct. Follow the instruction in the rootfs release thread and create a USB rootfs

Scroll down to

Updated 25 Aug 2019:

Basic Debian buster Kirkwood rootfs for most Kirwood plugs:

And do Steps 1 to 5.

After that, you have a rootfs on USB.

You can create the USB rootfs on another Linux machine, or inside Rescue system. But it is separate from what you need to do to install u-boot.

thanks, Bodhi.

But the pogoplug could not restart again. the light keep blinking in yellow. I could not find it's IP on my router anymore. I have been working on it for weeks by guessing and imagination. Finally it's over.

Thanks for the help though.

your envs are not correct, for start

Mount usb drive on other linux box

the easiest way was just to make a copy the environment variables from the "uboot.2016.05-tld-1.environment.bodhi.tar"

and just make a new uEnv.txt from it. cp uboot.2016.05-tld-1.environment /boot/uEnv.txt

make a regular(step 4a) new uImage and uInitrd on your linux box


this worked for me, otherwise you have to resort to serial console and get into the uboot shell, since its only a matter of the envs first.


the easiest way is via an other linux box or Raspberry pi (since it already has 2 serial ports, 1: 3.3v and 1: 5v. (i have RPI1 and ttyAMA0 can be enabled through raspi-config. or use usb-serial adapter.

then use kwboot as portable serial terminal without the image injection, or install screen: screen /dev/ttyAMA0 115200 and connect pins 14-15-16 (GND/TX/RX)

puzzlednewbie,

When it binks yellow, it means that u-boot has started (ie. your u-boot installation is most defitnitely successful). But it could find the kernel files on your USB rootfs.

So if you'd like to continue, I will help to get it booting.

Make sure you create the USB rootfs correctly. Use a different Linux host to do this (any Linux laptop or dekstop would be fine ). Follow the instruction in the rootfs creation. And post the entire session log while you are doing that (Copy everything on your terminal on that Linux host) and post the log here.
