[U-Boot-Users] Bootm hangs on SMDK2410 varity

[Mark]

I had success in porting the U-boot-1.1.4 to a varity
of SMDK2410 board. 
But I found the bootm command does not work as
expected.

When booting from zImage with go command:

HH2410STUDY# tftp 31000000 zimage
dm9000 i/o: 0x8000300, id: 0x90000a46

HH2410STUDY# go 31000000

done, booting the kernel.

Error: a

This is understood and expected. Because the go
command did not pass the archtecure # to kerner.
That's why
it says "Error: a".

On the other side, this proves the console setting is
right because it received the msg from the kernal.

When booting from uImage with bootm command:

HH2410STUDY# run uimage

The operation system hangs here.

I double checked the uimage making process and it is
right. Here it the command list:
	arm-linux-objcopy -O binary \
				 -R .note -R .comment \
				 -S vmlinux linux.bin

	gzip -9 linux.bin

	mkimage -A arm -O linux -T kernel -C gzip \
		-a 30008000 -e 30008000 -n "ARM Linux Kernel" \
		-d linux.bin.gz uImage

BTW, I also tried to set up bootargs by setting
without success:
	console=ttyS0 baudrate=9600
	console=ttyS0 baudrate=115200 and etc 

Any hints why this happen?

If possible, please copy me on reply. But anyway I
should go to list achieve to check the reply. Thanks a lot!
