hi guys,

thanks for the good work, I now have my dreamplug, and want to install the OS from the external SD card, instead of the internal micro-sd. My OS of choice is debian stable... How do I go about installing that ?

I do have the jtag module, so I can get to the uboot.

G  

Looks like I will have to wait for you guys to develop a custom uboot for the dreamplug which can support booting from the SD card, and also will work with debian stable..

The current u-boot seems to be
arvell>> version

U-Boot 2011.06-02334-g8f495d9-dirty (Mar 01 2011 - 06:57:05)
Marvell-DreamPlug
Marvell>>

which is apparently some version customized for the dreamplug....

Can you guys provide some note/instructions on switching this to WLAN client mode instead of AP...

I am a linux expert, but new to the plug, (except my nslu2), I really hate when people load stuff from
rc.local and /root/ at boot up, it seems to show that the OS is handicapped.. Can't they just do it in a more
modular way through init or something...

Here is what I have tried so far,
1. purchased a 8GB micro-SD and instaled it  in a USB reader, and put it on one of the USB slots
2. installed a std SD card in the SD slot...
3. the micro-sd of 1, has 3 partitions,
   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 tthe /etc/fstab to add a line to mount the part 3 using UUID under /home/

4. at the (default) uboot prompt I give..

Code: [Select]

setenv x_bootcmd_kernel fatload usb 1 0x6400000 uImage
setenv x_bootargs_root root=/dev/sdc2 rootdelay=10
and then a printenv tells me...

Code: [Select]

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

x_bootargs_root=root=/dev/sdc2 rootdelay=10

Environment size: 524/4092 bytes
Marvell>>

next I run

Code: [Select]

run bootcmd

The system boots from the uImage from the fat partition on the USB drive, and then loads the rootfs from the partition on the USB drive, the fstab also automounts the /home/ based off the UUID...

The SD card (in the provided slot) shows up as /dev/sdb* however the default uboot does not have support for that slot, so it does not show up in uboot, (there is no mmc option in the factory uboot), so it is not possible to load the uImage from the sd card. However it seems possible to load the rootfs from the sd card (not tried it yet)
by giving the option

Code: [Select]

x_bootargs_root=root=/dev/sdb1 rootdelay=10

Next I am going to try and use
one of... the uImage, uInitrd's from

ftp://ftp.debian.org/debian/dists/stable/main/installer-armel/current/images/kirkwood/netboot/marvell

there is no dreamplug there, but I guess, the guruplug one will probably work... not sure...

[sigterm9]

I'll do a writeup later on it but for now....
seem's to work...

Update...

I was one of the 400Mhz nightmare-plug guys, now waiting for replacement....

G

[mdawkins]

How did you know you were a 400MHz problem?

I've had nothing but problems with mine so far. Seg faults make it literally impossible to do anything with it.

[ghat]

hi

do a

cat /proc/cpuinfo

Bogomips should be close to 1200 (Mhz), mine was 396...

G
[ you should also somehow test your memory and sd card for errors ]

[ghat]

Update..

- Got the new dream plug,
- booted back from USB with the initial image I had developed.
- formated the internal microsd to get a bigger boot partition, and
  reformated the factory-rootfs
- installed the factory-uImage on the boot partition
- installed the factory-debian-rootfs (some old version) from the download site
- updated that root-fs to current debian stable, and it works...(still not
   truely debian, as it does not yet run the debian kernel)

hi

OK, now I have the new uBoot, and am trying to boot from the "external" SD card.
I have a card with 2 partitions, FAT16 for 1st and ext3 for 2nd.

I have downloaded

http://ftp.us.debian.org/debian/dists/squeeze/main/installer-armel/current/images/kirkwood/netboot/marvell/guruplug/

into the 1st partition.

I get to uBoot and do the usual

Code: [Select]

mainlineLinux=yes
arcNumber=2659

(the arc number is the decimal version of the arch from the bdinfo output)

I am able to load the uImage and uInitrd at 0x00800000 and 0x01100000 respectively,
set the bootargs as

Code: [Select]

bootargs=console=ttyS0,115200 base-installer/initramfs-tools/driver-policy=most

however if I then execute

Code: [Select]

Marvell>> help bootm

At a guess there is an issue with the tty device. You may find that sshd is running; if you can ssh in you should be able to poke around (if necessary create the tty device). Can you ssh in?

I tried that, scanned my whole intranet for any open ssh port, nothing...
tried the (older) sid image also, but it does not even boot.

any other uImage/uInitrd I should try ?

is the arcNumber=2659
 correct ?


Is there any bootarg which I should try to force a ssh server install ?

currently I am doing this

Code: [Select]

printenv
setenv ipaddr 192.168.2.95
setenv serverip 192.169.2.5
setenv bootargs console=ttyS0,115200n8 base-installer/initramfs-tools/driver-policy=most rootdelay=10 root=/dev/sdb2
tftpboot 0x01100000 uInitrd.squeeze
tftpboot 0x00800000 uImage.squeeze
printenv

bootm 0x00800000 0x01100000

same result..

update:
even tried

Code: [Select]

tftpboot 0x6600000 uInitrd.squeeze
tftpboot 0x6400000 uImage.squeeze
bootm 0x6400000 0x6600000

same result... nothing...

arcNumber is a switch that is used to enable (or disable) features within kernel code. The only people who can advise on a suitable arcNumber are those who compiled the kernel in question. The Guruplug arcNumber is 2659, but has anyone said that this kernel is usable in the Dreamplug?

It's my understanding that there may be problems with NAND initialisation on the Dreamplug (because there isn't NAND); I believe that James may have a suitable kernel. See here

hi

There is something missing in the default debian kernel perhaps...

I was able to bootstrap the installation, into the external sd card create a uboot image and try to boot from there...

There's a new document available from Globalscale, "Set Up A Debian File System In DreamPlug-20110423":

http://code.google.com/p/dreamplug/downloads/list

My guess is that there is something (missing?) in your rootfs (you said "bootstrap", can I infer that you used debootstrap?) that is the source of the problem. When we build a Sheevaplug Debian rootfs we use a variation of Mark Gillespie's script. In particular, the script must add a tty device, which is why I mentioned in it my earlier post. But maybe there's something else we haven't considered.

I don't know when I'll have a chance to try the new GST / Debian procedure, but you should be able to use the rootfs they supply, if that sounds like a reasonable next step?

I am now running the latest sheeva.with-linux kernel using the guruplug arcNumber.  OS is squeeze.  Seems stable so far.

elementry my dear mr Marcus (watson)...

Well, I guess I already mentioned that I reformatted the micro-sd and installed the gst debian on it and upgraded it to the latest squeeze with no issues.

I was hoping that a "default" or "vanilla" debian (incl kernel) would run on the device, but looks like it does not. I lso got the new Uboot in s I can now use the external-sd, and am experimenting with it. I first booted to the working micro-sd, and then mounted the external-sd and installed debootstrap on to it and later booted to th external-sd and completed the debian install. The debian installed fine, and also installed the vanilla debian kernel, but it hangs.... If I use the GST uImage, I can boot to this new debian-rootfs and that also works... no issues.

I just have to now figure how to compile my own kernel on the system.

I just got the sheeva-with-linux kernel to boot...
