hi
im having a MPC860T based board with
an hardware watchdog on it. It must be
triggered within a second, otherwise
the MPC will be reset.
In eCos applications i am having a
separate thread triggering the watchdog.
No problem.
How should i deal with it in RedBoot:
Currently i scattered several of
TOGGLE_WATCHDOG macros into the
RedBoot code, but this should only
be a preliminarily solution.
What do you think about using some
of the timer interrupts for generating
the watchdog triggers.
Thanks for advice, and how to start.
best regards, christoph
