[U-Boot-Users] 1.1.4 and 2.6 kernel

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 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.

Regards,
Alfred
