Hi, I'm trying to get Linux running on a Motorola Sandpoint. I have a
8240 and a 7400 available.
So far I've tried running the 8240 kernel from the Montevista CDK 1.2.
The boot seems to hang after printing the "OpenPIC timer frequency is
not set" (I left it waiting for quite a while with no luck). I get
the same thing on both the 8240 and the 7400.
Then I tried the older kernel from
<ftp://ftp.mvista.com:/pub/Area51/sandpoint-8240>
That kernel seems to freeze up at the same place (it prints more
openpic information, but those print statement just seem to have been
taken out of kernel 2.4 -- I can send them if it would help diagnose
the problem).
Has anyone gotten Linux to boot on a Sandpoint system? I'm especially
interested in the 7400.
Also, if I wanted to build my own kernel for a Sandpoint system, what
source tree should I use? And (forgive the naive question) how do I
build a kernel image that I can send to the Sandpoint via the serial
port and start from DINK32? What are the prospects of being able to
build a PPC kernel from Linus's tree?
Thanks,
Roland

Got all of those switches set correctly :-)?

Yeah, I'm working on the 7450 as we speak. Probably won't sleep
this weekend because I need to have the demo done for Linux world.
The Linux part was easy, the demo sucks :-). I did the original
8240 long ago, which was some "up to date" 2.3.18 kernel or something
at the time. I'm sure that is still floating around someplace :-).

Let me clean mine up a little (I'm actually doing 405 at the moment)
and put it on a server someplace. No promises, but it should be
better than anything else right now. The Sandpoint seems to always
be one of those "background" projects that can't gain momentum.

What version of DINK do you have? I'll send you my little downloader
as well if you wish. The easiest way is I just blow the bits over
the JTAG with my Abatron....

It's getting closer, but this Sandpoint stuff still isn't there.
