hi guys,
this is how far I have been with the globalscale dreamplug which has recently
started shipping.
The content here is still not "debian" yet, as the guy ships with ubuntu 9.04
preinstalled. I am new
to the plug (though have worked with the NSLU2 for quite a few years).
The factory U-boot

Cannot figure out what version of u-boot that is, however does not support mmc,
or the external (full size) SD card slot for booting the uImage
however it does support booting from either of the 2 USB ports.
I installed a 8GB stick on one of the USB ports (actually USB micro-sd reader)
and did the following partition.
part 1 => fat32 => contains uImage from the globalscale download site (250MB)
part 2 => ext3 => untar-gzipped the rootfs from the globalscale download
site (2GB)
part 3 => ext3 => empty but formatted partition (rest of the sd)
I updated the /etc/fstab on part2 to add a line to mount the part 3 using UUID
under /home/
Also installed a full size SD card in the external slot (to see what it does)
On the factory-uboot I can see both the internal-sd (as usb dev 0 ) and the
external usb-stick
(as usb dev 1). so I can boot/load the uImage from both the internal-sd or the
USB device.
The Factory uImage
The factory uImage, which is the same as the one on the globalscale download
side (dated mar 3 2011)
identifies the internal sd card as /dev/sda, the external-SD card as /dev/sdb
and the USB stick as /dev/sdc
It also identifies the /home partition by the UUID and mounts it correctly
under /home/
How to boot from External USB stick (both uImage, rootfs)
I am using a Jtag with the device, so note that, I have not experimented
without it.
on the u-boot prompt
setenv x_bootcmd_kernel fatload usb 1 0x6400000 uImage
setenv x_bootargs_root root=/dev/sdc2 rootdelay=10
then run the default boot command
run bootcmd
[Note: the printenv before I run the bootcmd looks like...
Marvell>> printenv
bootcmd=setenv ethact egiga0; ${x_bootcmd_ethernet}; setenv ethact egiga1;
${x_bootcmd_ethernet}; ${x_bootcmd_usb}; ${x_bootcmd_kernel}; setenv bootargs
${x_bootargs} ${x_bootargs_root}; bootm 0x6400000;
bootdelay=3
baudrate=115200
x_bootcmd_ethernet=ping 192.168.2.1

Notice that the uImage is loaded into 0x6400000 (the factory setting)
Thats all, the system boots correctly.. as expected...
Given that the default uImage identifies the external-sd card as /dev/sdb, I
guess we can install a ext3 formatted card in the sd slot, and also load the
rootfs from there... I have not personally tested this (I don't have any spare
card with me), one would then have to use /dev/sdb1 in x_bootargs_root
then...
TO-DO Installing debian
Here is where I have all the questions, for you folks...
0. No installers available from debian for "dreamplug"
1. What is the arcNumber to be used with this device ?
Hint:
Marvell>> bdinfo
arch_number = 0x00000A63
env_t = 0x00000000
boot_params = 0x00000100
DRAM bank = 0x00000000
-> start = 0x00000000
-> size = 0x10000000
DRAM bank = 0x00000001
-> start = 0x10000000
-> size = 0x10000000
DRAM bank = 0x00000002
-> start = 0x00000000
-> size = 0x00000000
DRAM bank = 0x00000003
-> start = 0x00000000
-> size = 0x00000000
ethaddr = F0:AD:4E:00:73:CE
ip_addr = 0.0.0.0
baudrate = 115200 bps
Marvell>>
So is it 2659 ? (decimal of arch_number)
3. I am planning on trying the available installers, however notice that the
uImage is loaded into
0x6400000 unlike the sheevaplug, so I am not sure what location I should
install the uInitrd to
Any hints/ suggestions, let me know...
If it helps, here is the boot message when the system starts up...
