Hello,
because Ubuntu on Sheevaplug is not supported, I decided to update my Sheevaplug to Debian Squeeze, on the NAND. I use the restore procedure to do that. This method only works with Globalescale, Ionics has different rootfs ! This method also updates the Sheevaplug to the current last kernel, 3.4.5.
All needed files are available here :
https://docs.google.com/folder/d/0BzksAE8XyQoAbG1yVjFHRW40SDQ/editprerequisite
------------
Your Sheevaplug need at least the Uboot 3.4.27. When you are in the Uboot prompt, and you enter the
command version, you may have this result:
Marvell>> version
U-Boot 1.1.4 (Dec 27 2009 - 22:03:21) Marvell version: 3.4.27 - pingtoo patch.01
uboot update if needed
----------------------
- use the file provided here : uboot-3.4.27.bin
- put it on tftp server or USB key
- install it on your Sheevaplug from Uboot command
from USB key
usb start
fatload usb 0:1 0x0800000 uboot-3.4.27.bin
nand erase 0x0 0xa0000
nand write 0x0800000 0x0 0xa0000
from TFTP server
set serverip 10.11.12.13
set ipaddr 10.11.12.15
tftpboot 0x0800000 uboot-3.4.27.bin
nand erase 0x0 0xa0000
nand write 0x0800000 0x0 0xa0000
- then, enter the command reset
sheevaplug update
-----------------
- only for Globalescale original sheevaplug
- you'll need a USB key in FAT or FAT32
- put on it's root these files : uImage, modules.tar.gz, rootfs.tar.gz
these is a 3.4.5 Linux Kernel and Squeeze rootfs
- plug these USB key to your Sheevaplug
- reboot your sheevaplug, and go to Uboot prompt
- set this command in uboot
setenv bootargs_console 'console=ttyS0,115200n8'
setenv mtdpartitions 'mtdparts=orion_nand:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs)'
setenv bootroot_nand 'ubi.mtd=1 root=ubi0:rootfs rootfstype=ubifs'
setenv bootload_nand 'nand read.e 0x00800000 0x00100000 0x00400000'
setenv nand_boot 'setenv bootargs $(bootargs_console) $(mtdpartitions) $(bootroot_nand); run bootload_nand; bootm 0x00800000'
setenv recover_ramdisk 'root=/dev/ram0 rw ramdisk=0x01100000,8M install_type=nand'
setenv recover1 'setenv mainlineLinux yes; setenv arcNumber 2097; setenv bootcmd run recover2; saveenv; reset'
setenv recover2 'run recover3; setenv bootcmd run nand_boot; saveenv; run recover5'
setenv recover3 'run recover4; nand erase clean 0x00100000 0x00400000; nand write.e 0x00800000 0x00100000 0x00400000'
setenv recover4 'usb start; fatload usb 0:1 0x00800000 uImage; fatload usb 0:1 0x01100000 initrd'
setenv recover5 'setenv bootargs $(bootargs_console) $(mtdpartitions) $(recover_ramdisk); bootm 0x00800000 0x01100000'
setenv bootcmd 'run recover1'
saveenv
reset
after few minutes, and some restart, you'll have a UBIFS system, with Linux kernel 3.4.5 (currently
the last update in August 2012) with Squeeze Debian.
The root password is always : nosoup4u
The directories /tmp and /var/log are tmpfs system. You can check them by the command df:
df
Filesystem 1K-blocks Used Available Use% Mounted on
tmpfs 256620 0 256620 0% /lib/init/rw
udev 10240 112 10128 2% /dev
tmpfs 256620 0 256620 0% /dev/shm
rootfs 472968 167008 301124 36% /
tmpfs 256620 0 256620 0% /tmp
tmpfs 256620 84 256536 1% /var/log
You can update the file /etc/fstab with this line (no set access time to file, to not write always on NAND)
rootfs / rootfs rw,noatime,sync 0 0
If you have a proxy, you can create the file /etc/apt/apt.conf with these lines for example:
Acquire::http::proxy "
http://myproxy:1234/";
Acquire::ftp::proxy "
http://ftp://myproxy:1234/";
Acquire::https::proxy "
https://myproxy:1234/";
You can add softwares with apt-get command, but don't use the upgrade command. Because it wants to update
your kernel in 2.6.32 (August 2012), while you have a 3.4.5 kernel.
These updates will be done at your own risk. I decline all damages which can arrived during the
update.
long life to the sheevaplug
