I'm working with an MPC880 board that is supposed to run linux-2.6.32. After
some work, I could get the kernel up and running, mounting a rootfs via
NFS.
2.6.32 is pretty old. Is there any specific reason for not using a
recent kernel version?
I think that all the kernel version has the same problem
The problem that I'm facing now is that when I try to run any process (may
be an ls, cat, or whatever), the response of the process is *very* slow
(something like 10 to 20 seconds for a ls).
This sounds as if only the output to the (serial ?) console port was
slow - typically this happens when there is a problem with interrupt
assignment, and you receive charatcers only after each of these times
out.
It is not a serial/console/interrupt problem
My question to all is, did anyone see something like this already? Besides
We have seen this many times in the past, when interrupts were not
working correctly. I recommend to check youyr device tree settings
for these.
[It would have helped if you had included a log of your kernel's boot
messages.]
that, what is the status of the linux kernel support for the 8xx platform?
It is working and actively maintained, but 8xx is a platform that is
more or less hopelessly obsoleted - nobody uses it in new designs any
more, so there is little work going on with it in recent kernel
versions (at least compared with other architectures).
agree, this architecture is basically dead
Is it being actively tested / used today? I ask this because it seems that
Yes, it is.
all the information on the internet very aged (forum discussions from 2005
and below mostly).
Is there something that I can do to try to narrow the cause of the problem?
Check your interrupts.
