Hi!
I am making my own uImage by compiling my Angstrom linux but whenever i am
copying this image in my at91sam9260 board, it is giving me an error message
while booting and working:
No filesystem could mount root, tried: jffs2
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(2,0)
Can anybody help?
uImage not workin

Anybody who is willing to help will probably need these information:
1) What is your command line arguments? (bootargs variable in u-boot)
2) Where are you trying to get your file system, nand? nfs? ramdisk?
3) Your kernel boot log
4) Do you have support for your file system in your kernel config?

Make sure your bootargs are correct. Please give printenv command at u-boot
and send the output.
Aman.
and send the output.

pratibha,
Can you please send the complete boot log so that it becomes easy to
identify the problem.
Also can you do a printenv at the u-boot prompt and send that output also.
Regards

Also, make sure you have your block layer set right - config = MTD2BLOCK.
That was my mistake the first time I did this on buildroot...

It was not a big issue. i was trying to program dataflash but i as nor
initialising it.
Actually, i had selected the type of dataflash i am using...but i cudnot find the option to initialize in menuconfig. When i was just looking at the .config file i saw dataflash had not been set there so i just initialised it there only and got the prblen solved.
