I have downloaded the patch form 'http://intr.overt.org/blog/',It includ two .diff files and one .bin file ,but i don't know hoe to use it ,though I have
see the Instructions for flashing the kernel are available at:
http://maemo.org/development/documen...uide_bora.html
,But I can't understand it ，I am a beginner of Linux.
I find a way to flash the kernel with a tool:"kernel_flasher",but it seems to flash the Nokia 770,I want to know how to use it on N800.

Another Qusetion:The kernel_flasher is only for .bin files,How to install another two .diff files? What's .diff file?

When I run " sudo gainroot "
then input
"time dd if=/dev/mmcblk0 of=/dev/null bs=8192 count=10240"
to test the speed,
it show "/dev/mmcblk0:Permission denide"Why?

Should I only intall the .bin file? and the .diff files are usefulless?
Can I flash the kernel from the MMC card? Or from the internel flash?
Too much I can,t understand.

If you plan to flash the kernel directly on the N800/770, then this might help:

You need to get the kernel_flasher tool and the actual kernel (.bin). You do not need those .diff files.

I don't think you can access a block device this way (or that is my guess). You may want to try writing to the /media/mmc1 with the dd command, such as:
time dd if=/dev/zero of=/media/mmc1/big_file bs=8192 count=10240

Then do a read of that file with dd (using of=/dev/null).

I hope this helps,

Oh,I know why it shows"/dev/mmcblk0:Permission denide",because I installed the X-term,but not to install"become root",After installed it ,it works ok.
Now I have flashed the kernel sucessfully!

Thank you,everyone.
