passing parameters to kernel from u-boot 1.1.6
Hi Everybody,
Iam working on changing the bootloader from redboot to u-boot 1.1.6 for my customised target board having IXP422 chipset.
The board had two files, one was the redboot bootloader (bin) file and second was the Image ( Kernel & Application .rmt) file. I guess that this Image file would not be dependent on the bootloader. Am i rite?
I have managed to get the console and network of U-boot 1.1.6 up on my customised board with the help of this forum :)
Now I would like to port the existing Image. How can I do it. Can anyone help me with this?
I have tried changing the "bootfile" env variable with the location of my image and reset the board, it gives the load address as 0x200000 then loading and some # hash's as if its loading something, inbetweens it gives, "bad checksum" and ends with the statement "bad magic number"
then i tried giving "tftpboot 0x00200000 uImage" it did almost the same , load address 0x200000, loading with some Hash # and then then gav ethe number of bytes tranfered, this time no error message.
then i tried bootm 0x200000but it said... booting image at 0x00200000 and then BAD MAGIC NUMBER.
how should i proceed with this. Pl Help!

U can use mkimage to make your binary image (kernel + fs), it is included with the u-boot sources in the tools directory.

Hi,
I tried mkimage comand on the host system where i had complied u-boot 1.1.6
localhost:$ mkimage -A arm -O linux -T kernel -C none -a 0x8000 -e 0x8000 -n "Linux 2.4" -d linux.bin uImage.bin
where linux.bin was the Image (kernel+application+fs) which was earlier used by my redboot bootloader.
Can someone let me know how we can decide the RAM address? how can we determine 0x8000 or something else. ?? i tried 0x200000 also but it didnt work.
When my u-boot boots, it says
From server 192.168.5.12; our IP address is 192.168.5.215 Filename 'uImage'.
Load address: 0x200000
Loading: ################################################## done
Bytes transferred = 6721600 (669040 hex)
## Booting image at 00200000 ...
Image Name: Linux 2.4
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 6721536 Bytes = 6.4 MB
Load Address: 00008000
Entry Point: 00008000
Verifying Checksum ... OK
Starting kernel ...
and then it restarts and agian does the same and restarts...
Help me!
