hi
i am working on a eCos port for the
MPC8260ADS board, and i am having
RedBoot working on the board
(ROM and RAM startup).
The port is based on the eCos PPC60x part.
Now i found this in the file
ppc60x/current/include/var_intr.h
// No builtin interrupt controller in the PPC60x CPUs.
followed by an "empty file".
I dont think, that the MPC8260 does not
have an builtin interrupt controller.
Another problem is:
The MPC8260 have "extra" exception vectors
0x1000 .. 0x1500 (MMU)
the PPC60x code does not define them.
(change code in PPC60x tree? )
Is it better to base the port on
the PPC8xx tree of eCos?
Am i getting more difficulties to do so?
Thanks for hints
regars, christoph
