Ray:
I have a hang using the debug firmware.
One data point to consider: I was running my ping script at 1 ping per second. I did not get a chance
to slow it down as you recommended. While the ping was running there was no problem. This morning
I stopped the ping. A few hours later I have a hang.
The data on the LCD:
Running OK:
28|1|4|B0|0|31
After hang:
29|41|4|B0|0|31
Hope this helps.
