If I'm not wrong, the 2.4 MTD driver and the 2.6 MTD driver is slightly different. In fact in 2.4 you have /dev/mtd0 and /dev/mtdblock0 representing the whole flash. In 2.6 /dev/mtd0 and /dev/mtdblock0 represent the first partition.
So maybe you can try with root=/dev/mtdblock3.
No hints regarding the console issue.

Hi Ilya,
Thanks for your reply.
Can you please help me understand what params you are referring to ?
I had changed my u-boot configs file to use: #define CONFIG_BOOTARGS "console=ttyS1,115200 root=/dev/mtdblock4 rw, mem=64M@0x00000000"
Note the change from default ttyS0 to ttyS1.
And linux bootargs I see xconf as : console=ttyS1,115200 root=/dev/mtdblock4 mem=64M@0x00000000
So, they look more or less ok ??
With same u-boot I can get 2.4 working. So, what could I be missing here.
Wolfgang: Apologise for html mail, my mistake. But I do see this issue as falling on the line between u-boot and linux. Not sure if linux guys will also push me to u-boot back again. So, please see if you can offer some advice.
Regards, Alfred

We already have u-boot 1.1.1 and 2.4 kernel working for us. But, while trying to get the 2.6 working.
I get the Booting image at XXXX XXXX Starting Kernel ...
And after that nothing.
At this stage I am expecting the "Uncompressing Linux ......"
Looks like kernel doesn't use serial console, have you provided correct console= boot argument?
What could be going wrong ? Same board, if I put in 2.4 on a 1.1.4 version u-boot, it boots fine.
Is it some tty redirection issue ?? Only change from IXDP425 board is sdram configuration and ttyS1 for console instead of ttyS0. Suspecting later but then 2.4 shouldnt' have also booted up ?
I'm pretty sure that serial device of your board was renamed from ttyS to something more specific in 2.6 kernel. Check this.
Second possible reason is that you don't have boot arguments support in u-boot (your 2.4 kernel may have precompiled boot arguments, check kernel configuration).
