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)

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. Tiju
