Dear,<BR>
<BR>
I am using u-boot-0.4.0 + linux-2.4.18-rmk7-swl8 + self-made ramdisk on smdk2410(s3c2410 cpu) board.<BR>
<BR>
Kernel is being successfully uncompressed and booted, but ramdisk isn't mounted.<BR>
My ramdisk is tested well on the same board and kernel without u-boot.<BR>
Ramdisk seems not to be loaded before uncompressing the kernel.<BR>
<BR>
The address where the kernel is being performed is 0x30f00000 and ramdisk's is at 0x30800000.<BR>
<BR>
System logs are as follows.<BR>
<BR>
THANK YOU...<BR>
