<p>Hmm, maybe clock driver code has been changed during the years
to read or write some register bits that are illegal on the
3-chip ERC32. This would cause a trap to error mode and most
likely a watchdog reset. I quickly looked through the ERC32
clock driver code but could not see anything obvious. It could
also be an ERC32 interrupt driver issue - enabling interrupts
seems to trigger the problem. I will try to run ticker on an old
version of sis that did some more checks for the 3-chip version

<p>One thing to look out for is the watchdog timeout. RTEMS does not
touch the watchdog, so if the board hardware or firmware does not
disable the watchdog, program that runs longer than a few seconds
will be reset by the watchdog. This would apply to ticker ...</p>

This configuration option enables the clock
driver.<br>

I would run first the RTEMS test suite on
your target. For example start <br>
with the ticker sample program.<br>
