Correct way to install customized kernel

[Jui-Hao]

Hi, all:

I am installing the latest pyramid-1.0b6.img.gz by copying the image
to the CF card on my routerboard. The kernel can boot without problem.
Afterwards, I want to add new driver for FDTI USB Serial converter
(fdti_sio.ko).
My building environment is a desktop machine with Ubuntu 8.04.
I use the latest source linux-2.6.19.2-pyramid.tgz and the /proc/
config.gz from the booted routerboard.

Can I simply copy the fdti_sio.ko module from desktop to CF card? or
should I replace the kernel (arch/i386/boot/bzImage) and the entire /
lib/modules/2.6.19.2-pyramid.metrix.net/ directory to CF card? (this
will replace all the modules.* files)

Hope to know the correct way to install the module, since I got
"unknown symbol" error message on that.

Many thanks,
Jui-Hao

Hi, I think I forgot to "make mrproper" to cleanup.
Now it's ok.

Thanks
