Hi All ,
I have downloaded the demo package from linux4sam from the following url:
ftp://www.linux4sam.org/pub/demo/linux4 ... 9263ek.zipthat is the last graphical demo available with linux 2.6.27 kernel.
I have followed the steps described in the page but instead of using the script
I have written the bootstrap, u-boot, linux and rootfs by hand in the following
addresses (taken from the tcl file):
Dataflash setup
Address File
0x00000000 dataflash_at91sam9263ek.bin
0x00008400 u-boot-1.3.4-exp-at91sam9263ek-dataflash_cs0.bin
0x00042000 linux-2.6.27-at91-exp-at91sam9263ek.bin
Nand setup
Address File
0x00400000 Angstrom-x11-image-demo-glibc-at91.rootfs.jffs2
I have attached file to the message since it is very long (log_SAM-BA_2.8.txt).
Everthing is ok and then I boot for configuring the U-boot variables.
From u-boot I configure the bootargs and bootcmd and boot the card (taken form the tcl file) .
The following are the messages I get:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)
As you can see there is an error telling that it is not possible to find the rootfs.
I have made several tries changing the bootargs, even using previous version (demo v1.3)
but none of them work and I get the same error.
Could somebody that has tried with this version or previous, tell me if I have made something wrong?
I have been trying during several days, so I will thank you very much for any clue
you can give me.
