Bootloader tips and tricks
Re: GoFlex Home failed install - 4 years ago
I got that many times when first starting... it could be an intermittent fault or a bad connection. I have several of these units with different connections. When you get the serial connection set up, do you see the unit trying to boot up? ...oops, just saw the log so you obviously can. Are you trying to use kwboot?

Re: Inaccessible Seagate GoFlex Home - 4 years ago
Many thanks, bodhi, I have it working now, to my great relief. Just wondering... if I want to use the unit with a 3.5 in disk, do I just copy all the files from the USB stick to the disk and maybe change labels and somesuch, or should I continue to boot from the USB stick and add a mount point in /etc/fstab for the hard disk?by balanga - uBoot
Inaccessible Seagate GoFlex Home - 4 years ago
Not been here for some time, but it's nice to see that the site is still active and bodhi is still sharing his great knowledge... I'm trying to recover a Seagate GoFlex Home unit which I messed up some time ago. The problem was that I mixed up two units, one which accesible by a serial cable and one which wasn't, and I made a mistake with my envars and now it doesn't boot aby balanga - uBoot

SheevaPlug - 5 years ago
I just bought a SheevaPlug on Ebay and it comes with Ubuntu installed. Apparently a Debian SD card is available for it according to:- https://www.newit.co.uk/shop/All-SheevaPlug/SheevaPlug-Accessories/Sheeva-Pre-Configured-SD What exactly is on this card? Presumably I can make my own... How would I go about it?by balanga - Debian
Re: Booting from third partition of disk - 5 years ago
I've never really understood how the Windows boot partition works either, so decided to leave that disk alone, just copied the Debian partition to another disk which I cleared down, and everything booted up OK. Thanks for the replies.by balanga - Debian
Re: Booting from third partition of disk - 5 years ago
It was just a quick way of freeing up some space on a Windows disk to install a Debian rootfs. Not sure how to move the Windows partitions to the end.... Any suggestions?by balanga - Debian
Booting from third partition of disk - 5 years ago
I have installed the Debian rootfs on /dev/sda3 and labelled it rootfs, but uboot doesn't want to boot from it. At the boot prompt, I run scan_disk and get the following:- GoFlexHome> run scan_disk running scan_disk ... Scan device usb starting USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... 1 USB Device(s) found scanning usb for storage devices... 0 Storagby balanga - Debian

Address in SROM - 5 years ago
I'm not sure of the origin of my current ethaddr but it does not corresond with the MAC address on the base of my GoFlex Home unit, so I thought I'd change it using setenv... but was surprised to see that the original MAC address was held in something called SROM. How do you display the original MAC address? Presumably the Product Key can also be accessed...by balanga - uBoot

bodhi, I did exactly as what you suggested but the outcome was the same so didn't see any sense in posting the same log as before and wanted to see if I could get uBoot to read uEnv.txt which I did by running the various functions in logical order separately, but I will post the output from the changes you suggested, although I don't know what you will glean from it.

bodhi, I don't think /boot/uEnv.txt is being read when booting from hard disk, irrespective of the contents.

Re: GoFlexHome RIP - 5 years ago
This particular 'sad' GoFlex Home unit has been sitting on a shelf for over a year, but just out of interest I connected it up yesterday, and it started blinking! It seems as though it has sprung back into life, but I'm not really sure what state it is in. Wiring it up to a serial port and running kwboot was unsuccessful, but I did note that the blinking green led changed to aby balanga - uBoot
