Hi all,
After uboot comes up, I get stuck with the booting of linux kernel. The RAM
range is from 0x30000000-0x38000000. Following are the steps I do to get the
uImage.bin.
$ arm-linux-objcopy -O binary -R .note -R ..comment -S vmlinux linux.bin
$ gzip -9 linux.bin
$ ../u-boot-1.3.2/tools/mkimage -A arm -O linux -T kernel -C gzip -a 0x30008000
-e 0x30008000 -n "Linux kernel" -d linux.bin.gz uImage.bin
Image Name: Linux kernel
Created: Sun Apr 6 12:19:12 2008
Image Type: ARM Linux Kernel Image (gzip compressed)
Data Size: 4271627 Bytes = 4171.51 kB = 4.07 MB
Load Address: 0x30008000
Entry Point: 0x30008000
After this I put the uImage.bin at 0x33000000, restart uboot and I get:
U-Boot 1.3.2 (Apr 6 2008 - 12:03:10)
DRAM: 128 MB

And it keeps on resetting the CPU.
Is it the problem with the settings of uboot or the kernel and what should I do
to bring the linux kernel up? Where could I find more information regarding
this?
Kindly help me out.
Thanks in advance.
