[U-Boot-Users] passing parameters to kernel from u-boot 1.1.6

[U-Boot-Users] passing parameters to kernel from u-boot 1.1.6

[Queenie]

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!

Queenie

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

[U-Boot-Users] passing parameters to kernel from u-boot 1.1.6

[Queenie]

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!
