Re: Possible fix for 'dual boot' problem with chained bootloaders - 14 years ago

I recommend using the mtd0 uBoot. The new mtd0 uBoot supports booting both USB and the old Pogoplug install. It will try USB first, and if that doesn't work, it will fall back to booting the Pogoplug install. The mtd3 uBoot will 'dual boot' USB on on boot, then Pogo on the next boot unless you use a 'workaround' like described above. -- Jeff

Re: Bootloader issue + kernel - 14 years ago

I'm glad it works! I'm sorry we lost one but at least you have 2 unlocked dockstars! For other people: Don't mess with the flash_erase commands directly. You can just run the uboot install script :) -- Jeff

Re: Cant boot into PlugOS but Debian - 14 years ago

The new bootloader will only boot into Pogoplug if there are no bootable USB drives attached. If you disconnect your drives and reboot, you should end up in Pogoplug. -- Jeff

Re: Bootloader issue + kernel - 14 years ago

Hi, A few important points: 1) You are very close to bricking your device. Be extremely careful. 2) The guide you are trying to follow will re-install the Pogoplug kernel. It does not affect uBoot at all. Your problem right now isn't uBoot, it's the fact that you've messed up what used to be your Pogoplug install. You *should* be able to boot into Pogoplug with the fol

Re: Install readonly embdebian on NAND - 14 years ago

To clarify, the entire NAND is only 256MB. By default, uBoot use 1MB on mt0 and Pogoplug uses 36MB on mtd1 and mtd2, leaving you with 219MB for an embedded installation. If you really don't want to keep Pogoplug as a backup for recovery purposes, you can free up an additional 36MB, giving you a total of 255MB to for your embedded install. The first 1MB must be reserved for uBoot. If yo

From the Debian command line, run fw_setenv set_bootargs_usb 'setenv bootargs console=$console root=$usb_root rootdelay=$usb_rootdelay rootfstype=$usb_rootfstype init=/sbin/init-ro $mtdparts' and then reboot. You should now have /dev/mtd3 -- Jeff Edit: fixed a typo, thanks Jörn

Re: Bootloader issue + kernel - 14 years ago

Your NAND isn't 128k, your sector size is 128k. If you've installed a new uBoot on mtd3, there is no 'original' to go back to -- it's still there on mtd0. Just change the bootcmd with blparam and you'll be back to the old Pogoplug install with no USB booting. From the Pogoplug install: /usr/local/cloudengines/bin/blparam 'bootcmd=run bootcmd_original�

Re: Install readonly embdebian on NAND - 14 years ago

/usr/sbin/flash_eraseall should have been installed by the 'mtd-utils' package. If it's missing, which is explicitly included in the install script. If it's not there then something went wrong with the installer (but not that wrong, since it still boots Debian). You can try manually installing the package with apt-get install mtd-utils -- Jeff

Re: New uBoot for mtd0 that can still boot original Pogoplug - 14 years ago

That command is old and doesn't work: ext2ls was wrong, it should have been ext2load. You can try the updated command that uses ext2load instead of ext2ls. You only have to run it once, not after every boot. -- Jeff

There's probably something funky with your USB harddisk. I've found that there are a number of USB devices with either old or cheap controllers that can cause boot problems. You should connect

Re: How to change rcS from Debian - 14 years ago

Re: How to change rcS from Debian - 14 years ago

You can mount the pogoplug partition from debian as follows: mount -t jffs2 /dev/mtdblock2 /mnt However, you should probably just install the new mtd0 uBoot which fixes the 'dual boot' problem that you're having. The new uBoot will always try to boot from USB first and, if that fails, it will boot the old Pogoplug install. -- Jeff

Re: New uBoot for mtd0 that can still boot original Pogoplug - 14 years ago

Syro, Yes, that's the section. I'm going to wait a few days to make sure that this works well for everyone on here and then I'll probably update the page and the installers to use the new mtd0 uBoot and mark the mtd3 stuff as the "old way." I think the new uBoot will fix 90% of the problems that are being reported in the forums. -- Jeff

8/22/2010 - New uBoot for mtd0 that can still boot original Pogoplug - 14 years ago

I've built a new uBoot for mtd0 that supports booting the original Pogoplug installation. This will fix all of the 'dual boot' problems that some of your are experiencing and will fix the boot problems related to a bad environment CRC. The installer saves a copy of the pogoplug uboot image to the root directory of the pogoplug environment (mtd2). When the new uBoot runs, it tr

Re: ext4 hard support in boot image uImage ? - 14 years ago

USB hard drives are fine. Ext4 should just be a matter of adjusting fstab and, possibly, the uBoot kernel parameters. Edit: Summary of changes for anyone else working on ext4: 1) run 'fw_setenv usb_rootfstype ext4' 2) in your Debian install, edit /etc/fstab and change ext2 to ext4

Re: Problem with USB Boot - 14 years ago

3) You should use fw_setenv and not blparam. That was a typo. It will configure the uBoot on mtd3 to boot debian squeeze and failing that, boot pogoplug. Yes, if you re-install Debian, it will configure the boot parameters correctly.

Re: Problem with USB Boot - 14 years ago

A few clarifications and ideas for everyone: 1) Unless you've changed things, the default setup will alternate between booting Debian and Pogoplug. If you don't like that, see here for a fix. 2) When you install Debian Squeeze using my scripts, you do NOT need to run any of the uBoot installer scripts. The updated uBoot is installed automatically to mtd3 and the boot environment

Re: ...kernel panic??? - 14 years ago

I've seen that error when uBoot doesn't read the uInitrd image. It can happen if you run the mtd installer again after running the debian installer. You can fix it by running the following from uBoot: setenv bootcmd_usb 'run set_bootargs_usb; run usb_init; ext2load usb $usb_device 0x800000 /boot/uImage; ext2load usb $usb_device 0x1100000 /boot/uInitrd; bootm 0x800000 0x11000

Re: Install readonly embdebian on NAND - 14 years ago

Yes, you can continue to boot from the USB drive by interrupting uBoot and typing run bootcmd_usb Alternatively, you can force it to switch to USB booting by running the following from your linux command line: fw_setenv bootcmd 'run bootcmd_usb; run bootcmd_ubi; run bootcmd_pogo; reset' Switch back to NAND booting with the following: fw_setenv bootcmd 'run bootcmd_ubi; run boot
