RES: SIS aplication interrupted with rtems4.8

[Fabrício de Novaes Kucinskis]

It works for me too (RTEMS 4.8.1).

The address you received in your error message (0x020001f0) is the default
address for the watchdog timeout trap, which has the opcode for a "ta 0"
instruction (91d02000).

I don't know if you have a modified version of SIS (don't remember now what
does SIS do to the watchdog, nor the BSP) but it's clear that your boot
loader is disabling the watchdog. Try to write something in the Watchdog
Trap Door Set MEC register at the beginning of your code to disable the
watch dog.

Runs for me with the CVS head.  I had sparc/sis built
and installed for testing something else so just threw the code at it.

Do you have MANAGERS=all in your Makefile or do you have
stubs?
