Hi
My custom MPC860 board does not start at power on. All that
happens is that the SW Watchdog resets the system after 5 seconds.
But if I connect my Abatron BDI2000 emulator with a stripped config file
that don't initialize any registers and type go at the telnet prompt
everything
is OK.
I am running PPCboot from Intel flash. The board has a 5MHz clock source and
is multiplied to 25 MHz during powerup.
Another problem,possibly related, is that I am unable to run the CPU at
higher
speeds than 40 MHz(and yes I run the bus at half CPU speed). According
to the emulator I get a external reset when I run at higher speeds.
Any pointers are most welcome :-)
Joakim
