Hi James, thanks for your reply.

I bought a Kingstone MicroSD 8gb Class4, and copy the image vía DD to the microSD, then I replace the internal microSD and place the new one, plug it. The green light on, but nothing seems to happen, I have searched in the DHCP list if there's a new conections but nothing.

Any idea of what could it be, and what else can I do?

@NewIT_James, great job!! I've put it onto 16GB microSD and it works beautifully. I've had a wonderful day playing with debian. Many many thanks.

Hi James,
Many thanks for this, and for the help getting it running.
It's been on for a week now, no problems at all.

Today I tried to connect my USB hard drive, but no luck.
The plug recognises the drive when I connect it, but I couldn't mount.
It is a NTFS drive, I use it in Windows without any problem.

I can see the drive is there with fdisk-l:
Code: [Select]
   Device Boot      Start         End      Blocks   Id  System
/dev/sdg1

But when I try to mount I get an error message:
Code: [Select]
[email protected]:/# mount /dev/sdg1 /mnt/hd
FATAL: Could not load /lib/modules/2.6.33.6/modules.dep: No such file or directory
ntfs-3g-mount: fuse device is missing, try 'modprobe fuse' as root
[email protected]:/#

I also tried modprobe fuse, but still I get an error:
Code: [Select]
[email protected]:/# modprobe fuse             
FATAL: Could not load /lib/modules/2.6.33.6/modules.dep: No such file or directory
[email protected]:/#


Could you please help?


Thanks.
FH

Hi Fabio,

Looks rather like you are running with the 2.6.33.6 kernel on the uSD card and Gui rootfs on the external SD. It's trying to locate the Modules for the 2.6.33.6 kernel on the SD card but not finding them.

I think you have probably not got the uboot variables quite right. Can you check the variable below is correct in your uboot settings. It's the '1' which refers to the external SD card ('0' would be the uSD).

Code: [Select]
x_bootcmd_kernel=fatload usb 1 0x6400000 uImage
Using the 2.6.33.6 kernel with the Gui image via vnc is not a problem if you prefer that kernel but you would need to  copy /lib/modules/*  from the internal uSD to the external SD card.

Hi James,
I am booting from an external SD reader (/sdc) and not from the Dreamplug car reader (/sdb) so uboot was configured as follows:
setenv x_bootargs_root root=/dev/sdc2 rootdelay=10

I did try setenv x_bootcmd_kernel 'fatload usb 1 0x6400000 uImage', but that did not work, it couldn't find the kernel.
fatload usb 0 works, but as you said it is reading the kernel from the internal micro sd (/sda).

How do I set uboot to read the kernel in /sdc? Tried usb 2, usb 3, usb 4 ... , no luck.

thanks.
FH

Hi,


I have same issue as spektro. I replaced microSD with the new 8 GB SD/HC one.

DP is not obtaining IP from DHCP. Just power LED is on. I'm unfortunately without JTAG. I have to order one ;-(

Any suggestions ?

Radim

UDPATE 18 June 2011: I did it ;-) Using UART/JTAG adapter I saw kernel panic. I tried to do "dd" copying again and modify boot variables. So I have two differences from my previous test:

1. I use /dev/sdb instead of internal /dev/sda
2. I copy SD card images on DreamPlug instead of my Debian virtual machine

I tested GuiPlug with VNC, it seems VNC is CPU intensive app. I can see through top, that it's using about 60 percent of CPU. I started browser too and CPU rises to nearly 100 percent. So i think gui is more usable with USB  monitor than VNC.

Anyway, it's very nice :-)
