[uClinux-dev] Initial Timer on m5329 not running
Hi List,
Coldfire 5329 seems not be used with latest kernels. The Main Timer is not
running, so the scheduler won´t behave like expected.
To change this the following change has to be done in m532x.c arch setup.
There is probably more to be fixed.

It's so easy the way we do this on ColdFire, I just cat them together. Well that does sound pretty easy. The kernel config for romfs made it sound a lot more complicated than that. I will stick with initramfs though since it works nicely, and having r/w access is sometimes useful when debuging things. initramfs does seem to lack execute in place which I highly suspect works on romfs, even though there doesn't appear to be any reason it shouldn't work for initramfs. -- Len Sorensen ___ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev

I found that there is a large amount of people who are getting the same problem in past couple of years. But I did not get any solution for the problem. Please let me know whether this problem still exists in uclinux source code for M5272C3. where I will find the solution for that?
