GuiPlug v2.5 for the Dreamplug is now available.

Use your Dreamplug as a Desktop PC either with a usb touchscreen monitor or VNC connection without a monitor.



Features:
 Debian Squeeze
 Gnome Desktop
 Kernel v2.6.38.5

The image can be used on either SD, eSata or microSD of at least 4Gb. If you are planning to use an SD I can't recommend the Integral Endurance cards enough, see here for the performance data. http://www.newit.co.uk/forum/index.php/topic,992.0.html

uboot variable changes recommended for SD boot.

Code: [Select]

x_bootcmd_kernel=fatload usb 1 0x6400000 uImage
x_bootargs_root=root=/dev/sdb2 rootdelay=10
mainlineLinux yes
arcNumber 2659

USB monitor / keyboard / mouse / 3g modem etc. can all be added if required.

Note: At Boot VNC server will only start if a Usb monitor is not found.

As well as a Desktop PC the Guiplug is capable of becoming a Citrix Client, Touchpanel control, NX client, RDP / VNC client etc.
Touchscreen Usb monitors are available from the shop here: http://www.newit.co.uk/shop/products.php?cat=16

Downloading & installing the image on your target drive:

Code: [Select]

wget http://www.newit.co.uk/drive-images/dreamplug/GuiPlug/NewIT-GuiPlug-4Gb-09May11-v2.5-Dreamplug.img.gz
gunzip -c NewIT-GuiPlug-4Gb-09May11-v2.5-Dreamplug.img.gz
dd if=/home/NewIT-GuiPlug-4Gb-09May11-v2.5-Dreamplug.img of=/dev/sdb bs=10M
All done, Now insert/connect drive and boot the Dreamplug.

If you are using VNC mode, to find the IP address of the plug either connect with the Jtag, logon and use the ifconfig command or Look in the DHCP client list of your router for an entry named 'GuiPlug'.

Passwords including root are set to 'nosoup4u'

Sorry New to the whole Dreamplug and arm thing but
Please make MORE CLEAR the Exact COMMANDS to be used
uBoot It sort of bites:

Code: [Select]

Marvell>> setenv x_bootcmd_kernel=fatload usb 1 0x6400000 uImage
## Error: illegal character '=' in variable name "x_bootcmd_kernel=fatload"
Marvell>>

Remember we are at the "Marvell>" Uboot Command line
What command lines do we need to put in?

BTW do both for External SD Card + USB Pen Drive

Hi hi_tech_guy_18,

How these appear from printenv:

Code: [Select]

x_bootcmd_kernel=fatload usb 1 0x6400000 uImage
x_bootargs_root=root=/dev/sdb2 rootdelay=10

How to set them with setenv:

Code: [Select]

setenv x_bootcmd_kernel 'fatload usb 1 0x6400000 uImage'
setenv x_bootargs_root 'root=/dev/sdb2 rootdelay=10'

How your commands looked:

You must use an 8gb sd card for the uImage. Because the file size is 3,9 GB

[NewITMalcolm]

Hi yancha22,

The image was created on the smallest 4Gb card that I have available so it should copy onto most 4Gb SD/uSD cards.
Alternatively use an 8/16Gb or eSata drive.

I need to format on FAT16 format ?

[NewITMalcolm]

Yancha22,

You need to decompress the image.

Code: [Select]

gunzip -c NewIT-GuiPlug-4Gb-09May11-v2.5-Dreamplug.img.gz

Then copy it to your SD/uSD device like this.

Code: [Select]

dd if=/home/NewIT-GuiPlug-4Gb-09May11-v2.5-Dreamplug.img of=/dev/sdb bs=10M
No need to format the SD card the 'dd' command will overwrite it and create the partitions automatically.

I have a kernel panic.

I use this procedure :

Download .gz file on newit server
Decompress file on a USB stick
copy from USB stick to sd card with dd command.

(for information i have 3 dreamplug, 1 JTAG and 1 mimo screen)

after
i connect JTAG module, insert sd card.
i boot
I have a kernel panic.

Do you think i need to create partitions on my sd card like this :
1st partition = uboot file
2nd partition = the newit guiplug img file

?

[NewITMalcolm]

I would guess the 'dd' command did not finish successfully.

Does the blocks in match the blocks out?

If not you need to try another SD card of a different brand or an 8gb or above.

Edit: Also the md5sums are there to download http://www.downloadsnewit.co.uk/SD-images/Dreamplug/GuiPlug/

[spektro]

Please some help here.

I followed the instructions:

Download the gz to my ubuntu laptop, then decompress to my HD, then copy to a SD card.(by the DD command as described) Put the SD card on my brand new Dreamplug, reboot, but!, nothing happens 

So then I though that the problem it could be the SD card, a Kingstone 8gb Class 4, so I bought a 8gb Class10, try it again, same issue, nothing happens, just boot from the internal MicroSD.

I don't have the Jtag, so I hope there's something else I can do to make it work.

by the way, I have checked the md5sum and are ok.

[NewITMalcolm]

Hi Spektro,

The changes to the uboot variables are what makes it boot from the SD card which obviously requires a Jtag. The only way to use the image without a jtag would be to copy the image to a microSD and swap it for the internal one.

[yancha22]

After two times. The first procedure work very well.

I can see the the desktop on mimo screen !!!

Thanks Newit!!

[yancha22]

For newbie like me use this command line and it work well:

Code: [Select]

setenv x_bootargs_root 'root=/dev/sdb rootdelay=10'
