Hi Koen-- Thanks for the explanations. One more question:

My second question is if it's okay and/or a good idea to change the _PR_append value instead? In looking at the meta-ti/recipes-kernel/linux/linux-mainline_3.2.bb I saw the line: MACHINE_KERNEL_PR_append = "a" ...and I was wondering if changing that to "b" would have the same effect as changing "r122" to "r123"? The location of the .bb file makes it easier to find than hunting down the omap3.inc file, so if it works just as well I'd rather change the _PR_append instead.Exactly! The PR_append is for changes to the kernel that don't influence external modules (sgx, dsp etc) and the MACHINE_KERNEL_PR is increased when external modules do need to get rebuilt.
When I'm in the process of making a kernel change, re-compiling, watching it fail, make another change, etc. it can be a bit of a hassle to bump up either MACHINE_KERNEL_PR or the _PR_append value. Instead, I've tried just touching the file .../linux-mainline-3.2/beagleboard/defconfig each time I make a change and then re-build. It "seems to work" but I'm not totally convinced that everything is in fact okay. Would you consider this an okay way to go or is there something I've overlooked (or don't know!)?
Thanks. _______________________________________________ Angstrom-distro-devel mailing list Angstrom-distro-devel@linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/angstrom-distro-devel
