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 MAC: 00:80:00:80:00:80 could not establish link TFTP from server 192.168.2.122; our IP address is 192.168.2.120 Filename 'zimage'. Load address: 0x31000000 Loading: #################################################################

#################################################################

################################################## done Bytes transferred = 916804 (dfd44 hex) HH2410STUDY# bootelf 31000000 ## No elf image at address 0x31000000 HH2410STUDY# go 31000000 ## Starting application at 0x31000000 ... Uncompressing Linux................................................................... 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 dm9000 i/o: 0x8000300, id: 0x90000a46 MAC: 00:80:00:80:00:80 could not establish link TFTP from server 192.168.2.122; our IP address is 192.168.2.120 Filename 'uimage'. Load address: 0x31000000 Loading: #################################################################

#################################################################

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!
