I have MM11-DP (16kW parity core) in my /04 which seems to have a little
problem.
Several locations which I've checked seems to be losing content (core is
supposed to be non-volatile). I've been debugging custom bootloaders
for the past week and it has since gone past annoying. It's like 3
locations out of 50 that are always reverting back to 000000 after a reboot.
Perhaps it's the driver logic to these 3 particular cores that are not
functioning properly? Or is it the cores itself?

Hi
It is more likely that a spurious write pulse is happening
when you power off. On my computer, you need to stop the
processor first before turning it off. If I don't do this,
a few bits get corrupted.

Hi,
A suggestion from my dad, Can you re-locate your bootstrap. If you do
do the same words zero out or do the new locations?

Hmm...I don't know whether it's spurious or not as it's always the same
3 locations..

Good suggestion. I'll try it and let everybody know.
