Re: [Ltib] Can LTIB compile just one single module without recompiling whole kernel???

[Quentin YANG]

Hi Stuart,

I am a bit confused now.

If keeping kernel source un-packed, how do I modify the 'spidev.c' source code?

The only thing I can think of is modifying 'spidev.c' and then zip it back into
"X:\lpc3250\ltib-qs\rpm\SOURCES\linux-2.6.34.tar.bz2" before running a
new build ' ./ltib '

Not sure is this what you suggested?
Please advise.
Thanks.


Regards,
Quentin
