can't load cmemk.ko

Other Parts Discussed in Thread: OMAP3530

Hi,

I am using a BeagleBoard xM

I want to:

$ insmod cmemk.ko phys_start=0x86300000 phys_end=0x88000000 allowOverlap=1

but:

insmod: error inserting './cmemk.ko': -1 Bad address

I have tried to create an uEnv.txt in /media/boot with:

bootargs=mem=99M@0x80000000 mem=384M@0x88000000

but it is no use.

I have tried before booting:

# setenv bootargs mem=99M@0x80000000 mem=384M@0x88000000

# saveenv

# boot

but I think that I have no NAND so it's no use:

Do you know what can I do to load cmemk.ko in that address?

Thank you.

Well, Robert Tivy told me that cmemk.ko is loading where I want.

Thank you namesake, Pramod Poudel, Prabhakar Lad, touse and Naveen kumar.
