Hi Henry,

Yes, you can make use of the older kernel (why can't you use the newer
one?  I'd be interested).

To do this, don't copy rpm/BUILD/linux, instead add the following patch
to config/platform/imx31ads/main.lkc


diff -u -u -r1.11 main.lkc

I'm guessing that the config file for 2.6.22 will be close enough to
work with the old kernel, if not simply copy the
linux-2.6.19-mx31ads.config (??) from the older BSP to the new on
(config/platform/imx31ads/) and correct the PKG_KERNEL_PRECONFIG in the
patch above.

Once you've done that, simply run: ./ltib --configure and select the
kernel you want.


Regards, Stuart
