[U-Boot-Users] 1.1.4 and 2.6 kernel

If I'm not wrong, the 2.4 MTD driver and the 2.6 MTD driver is slightly
In fact in 2.4 you have /dev/mtd0 and /dev/mtdblock0 representing the whole
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.

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 at 0x00000000"
Note the change from default ttyS0 to ttyS1.
And linux bootargs I see xconf as :
console=ttyS1,115200 root=/dev/mtdblock4 mem=64M at 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.
