Install U-boot on usb-stick?

Hello folks

I've been reading a lot of tutorials about how to install u-boot on the pogoplug. I now have Archlinux installed on a USB-stick following these instructions, provided by Moonman and probably known to the most of you:
Install Alarm

Basically I have everything set up the way I want to, except for Netconsole. For that I need to update U-boot, as explained on this page:


I do have a question though: my Pogoplug only boots with the USB-stick (due to a power failure I had recently), so without it does not boot anymore (green led does not turn on).

Does this mean that the U-boot is installed on the USB-stick itself?
Can I update U-boot according to the instructions I found on the above URL, with the USB-stick plugged in? The installer wants to install U-boot on /dev/mtd0, which I believe is not mounted in my current config.

Will I brick my installation if I try to update U-boot via this way?

The link where I found how to install U-boot does not seem to show up correctly:
Install U-boot

thomas,

Which Pogoplug do you have? there are many different variations.

No, it means if you have run the Arch installation procedure recently, then u-boot was installed in NAND, and the USB stick is the only way you can boot.

No, Jeff's u-boot is quite old. I have new one here (see my signature for the appropriate u-boot, i.e. Kirkwood or Oxnas).

Yes.

More information is needed before I can recommend solution for what you want to do:

1. Which Arch installation did you run?
2. And Information about your Pogo.

Hello Bodhi

I have the pogoplug E02 running, the pink one.

Concerning your question about the installation I ran:

Here we go again  :roll: 

1. Download a Linux Live CD (get kubuntu live cd, it's more like windows)
2. Burn and boot that cd on your PC (or use a USB flash drive, whatever works for you)
3. Connect the flash drive you want to boot from to this same PC
4.Go to K --> Applications --> System --> Partition Editor
5. Format this flash drive as ext3, label it "rootfs". Make sure rootfs partition is <=20GB.
6. After it's done formatting, remove and reinsert the flash drive. Open file manager and open this flash drive at least once (so it gets mounted)
7. Open terminal and copy paste the following (not everything together, but line by line)
CODE: SELECT ALL
sudo su
cd /media/rootfs
wget http://archlinuxarm.org/os/ArchLinuxARM-kirkwood-latest.tar.gz
tar xvzf ArchLinuxARM-kirkwood-latest.tar.gz
sync #may take a while
cd /
umount /media/rootfs

I followed these instructions, basically.

fw_printenv

[root@pogoplug tmp]# fw_printenv
bash: fw_printenv: command not found
[root@pogoplug tmp]#

fw_printenv does not work because my U-boot is too old for that.

Thomas,

You have not posted the Arch installation link/page (you only posted how you created the rootf). And dmesg output got chopped off (what is the Arch kernel version?)! So I'm going by what information available here:

- you are running the latest Arch Linux rootfs.
- the rootfs is non-FDT (so sign of device tree hints).
- you have installed Arch recent u-boot (you must have, based on mtd information).

This is not true. You need to install mtd-utils before you have fw_printenv/fw_setenv command available. And while you at this, print the content of the fw_environment.cfg file (where the u-boot envs are defined in Linux), it should look like below:

cat /etc/fw_env.config

# MTD device name	Device offset	Env. size	Flash sector size	Number of sectors
/dev/mtd0 0xc0000 0x20000 0x20000

If all I've determined above were true, you could either install Arch u-boot, or my u-boot.

This is not true. You need to install mtd-utils before you have fw_printenv/fw_setenv command available. And while you at this, print the content of the fw_environment.cfg file (where the u-boot envs are defined in Linux), it should look like below:

cat /etc/fw_env.config
# MTD device name Device offset Env. size Flash sector size Number of sectors
/dev/mtd0 0xc0000 0x20000 0x20000

I have installed mtd-utils, but the commands fw_printenv/fw_setenv are still not available to me. Also the file fw_env.config does not seem to exist in my current config.

Concering which installation I ran: This is the page where I got the instructions from:
Alarm Forum
I usually did it via the info I found here:
Alarm installation guide for E02

Thomas,

- So we've confirmed that you are running new u-boot and kernel from Arch.

- For fw_setenv/printenv: install u-boot-tools, too. And then create the fw_env.config with the content I've posted above.

Hey Bodhi

thanks for your help so far. I did as you told and got fw_setenv/printenv working. I also created the file /etc/fw_env.config with the line as you explained.

However, for some reason I cannot seem to get output from netconsole.

My u-boot config looks like this:

[root@pogoplug alarm]# fw_printenv
baudrate=115200
bootcmd=usb start; setenv letter 9;for type in usb; do for disk in 0 1 2 3; do if ${type} part ${disk};then setexpr letter $letter + 1;run load;fi;done;done;
bootdelay=3
bootm=echo Booting from ${disk} ...; run setargs; bootm ${loadaddr};
bootz=echo Booting from ${disk} ...; run setargs; bootz ${loadaddr} - ${fdt_addr};
console=ttyS0

fdt_file=/boot/dtbs/kirkwood-pogo_e02.dtb

zimage=/boot/zImage
ethaddr=00:25:31:04:97:77
serverip=192.168.1.3
ipaddr=192.168.1.6
if_netconsole=ping $serverip
start_netconsole=setenv ncip $serverip; setenv bootdelay 10; setenv stdin nc; setenv stdout nc; setenv stderr nc; version;
preboot=run if_netconsole start_netconsole
[root@pogoplug alarm]#

The serverip is the IP of my own desktop, which I would like to use to receive messages from netconsole. Ipaddr is the IP of the pogoplug. These are fixed IP's. Also, the Pogoplug and my desktop are connected to the same router and I have opened port 6666 (UDP) on my router to make sure that the communication would come through...

On mydesktop, in Ubuntu, I type:

nc -ul 6666

After which I reboot my pogo via "reboot" on SSH.

However, nothing is being displayed on my desktop. Am I missing something here?

A couple things to check:

- Make sure you're running the latest Arch u-boot. The first Arch version does not have netconsole support. You can verify this at Arch site.

- If you're running the latest Arch u-boot, then check netconsole version on your Ubuntu PC. You need to install netcat traditional, not the default netcat that is on Ubuntu (BSD).
- And use either of these 2 variations to connect with input enabled in a single command:

nc -lup 6666 192.168.1.6 6666

or

nc -kup 6666 192.168.1.6 6666

Hey Bodhi

Thanks a lot!!

Got it all sorted out. Netconsole is running properly on the plug now:
