I have 3 P8X32A boards, 2 Quickstart boards with built in USB and 1 schmartboard which needs a Prop Plug.
The schmartboard quit, everything looks fine. You can check the ID of the chip, prop plug looks fine in device manager.
Both Simpleide and Propeller say the code verified but Viewport says the code is not good. The chip will not do a blink
or send 'hello' to the terminal.
Is there anyway to verify the chip is dead. It has the standard 5 MHZ crystal. Could the prop plug be bad even though
it ID's the chip. I do have activity on RX and TX.
Can the reset from the prop plug be checked. I have tried to read it with a meter, my Oscope and my logic analyzer.
The meter reads 3.3 volt and stays there, the oscope wiggles and the analyzer shows a pulse occured but I do not know
the threshold for the pulse.
I have not used my 2 good boards as test subjects, hoping someone knows.
Any help would be great !!
