Now that we have linux going on the brutus, we are trying to get tcp/ip
stack
and PPP working as a sort of exercise in climbing the learning curve.
Ultimately, we need to get Linux going on an sa110 based box. This one
has only 8mb dram, 4mb flash. Mouse/keyboard internface, 2 serial
ports, an eithernet interface and a tl750 video graphics chip (plus support
chips).
What would be the issues on bringing up linux on this box? We should be able
to use the same process as we did with the sa1100 (download via angelboot
over
the serial port). Address map is different of course so we need to tweek the
kernel there as
well as recompiling for the sa110. Also, would we need to recompile c
library and
other utilities that go on the ramdisk? The ramdisk was built with the
brutus in mind but
I feel that the binaries should run on a sa110 based box.
I'm not sure what to do about the video graphics chip. There are some low
level
board support routines in C that are OS independent. We may need to have our
application talk direcltly to these instead of trying to write a driver for
Linux. After
all, we don't expect to be running X applications on our box.
Any insights would be appreciated.
thanks
