8/25 - new mtd0 uBoot with better USB support

I've updated the mtd0 uBoot again with some fixes for some USB devices. If you're having any troubles getting things too boot, this upgrade is the first place to start.

To upgrade (from the instructions for installing mtd0 uBoot):

cd /tmp
wget http://jeff.doozan.com/debian/uboot/install_uboot_mtd0.sh
chmod +x install_uboot_mtd0.sh
./install_uboot_mtd0.sh

-- Jeff

You say that it is only tested with Pogoplug v2. How do I know which version of the Pogoplug I have?

This is how my Seagate DockStar looks like:

There's only one type of Dockstar, so you're fine. The Pogoplugs are completely different devices and very easy to tell apart (one is bright Pink, the other is not).

-- Jeff

Thank you Jeff, its working fine.

I have two drives connected, one flash drive with debian and another USB hard disk for storage. Do I have to make any changes so that it boots always from the flash drive, like you had posted earlier while using the old uboot?

If you want to have multiple storage devices connected, you still need to use the USB Scanner script.

-- Jeff

^ Thank you so much. Everything is working perfectly now. :)

Jeff, I went through the install, on the pink pogoplug, everything seems to be working although, I did see errors when I run the script (related to blparam I'm guessing), plus I had to specify my device since it couldn't detect.

Should I be worry? script finished with "# uBoot installation has completed successfully."

Some of the errors:

Thanks

You're correct, the errors you're seeing are coming from a corrupted blparam environment. That's one of the errors that the new uBoot fixes so you should be fine now. The installer is very careful and would have given you a big scary warning if it couldn't install properly.

i've tried using below code


fw_setenv usb_init 'usb start; if ext2load usb 0:1 0x800000 /boot/uImage; then setenv usb_device 0:1; setenv usb_root /dev/sda1; elif ext2load usb 1:1 0x800000 /boot/uImage; then setenv usb_device 1:1; setenv usb_root /dev/sdb1; elif ext2load usb 2:1 0x800000 /boot/uImage; then setenv usb_device 2:1; setenv usb_root /dev/sdc1; elif ext2load usb 3:1 0x800000 /boot/uImage; then setenv usb_device 3:1;setenv usb_root /dev/sdd1;fi;'

since then i'm unable to load debian...

can you give me the default value of usb_init...

fw_setenv usb_init 'usb start'

hi...i've tried the default value, but its still not booting....please help me...

Just re-run the uBoot installer, it will reset the environment.

i've tried re-running uboot installer...and even couldn't boot into debian...

so, i've again reinstalled debian into another usb and now its fine...

i want to know if in case of power loss while using it, will i get the same problem again...

also, as with the boot order problem...

what i've noticed it..

case1) when i use the usb with debian on any of the 3 usb's on sides:

it will boot into debian properly, but if there is any other usb device then it wont boot....

case 2) i've newly installed debian on freeagent go, and now i can boot into debian no matter how many other devices are connected at sides...

so i think there is default usb1-usb2-usb3-usb4 thing...

and if i use freeagent go on stock port, it always takes it as sda1...

did you notice it...

You should connect a serial cable or configure netconsole to watch the boot process. When you can see what it's doing, it much easier to figure out what's going wrong.

I'm not able to run this version of u-boot from RAM -- should I be able to? The CPU resets as soon as I use the "go" command:

Hey Jeff, thanks for your shiny new uboot which I've just installed. I tried to configure netconsole with the fw_setenv command but I'm getting

fw_setenv: command not found

Did is missed something?

The uBoot installer puts fw_setenv/printenv utils in /usr/sbin of your Pogoplug installation. The Debian uboot-envtools package will put them in the same place. If you're running something else, you can just reboot into Pogoplug and run or copy them from there.

Is there a way of integrate the commands on my usb plugbox-os?
