Do you have /dev/ram0? is it mapped to 0xa0000000? there could be
issues with mach-types.. I am not sure though.. I am not entirely sure
about imx boot procedure(I am an OMAP guy ;) )..but it could be uImage
you need there? I am not too sure.. does the piggy relocate the
kernel? I am not too sure.. probably the kernel details would help..

Should'nt this be bootm 0xa0100000?

Hi All,

The " bootm 0xa0100000"  option is not helping.... It's displaying "could
not open : No Such file or directory" And the help  says the option is bootm
[option] image. But nothing helps.

The image being tried is getting loaded on the same board when board is
flashed with redboot using the following commands.

	1) load -r -b 0x100000 -m xmodem zimage
	2) load -v -r -b 0x01000000 -m xmodem  ramdisk.gz 
	3) exec -r 0x001000000 -s 0x00600000 -b 0x100000 -l 0x00200000 -c
"init=/linuxrc console=ttymxc0,115200 root=/dev/ram"

If any suggestions, please share..!!

Thanks,
Lejin
