We have just produced some boards that uses the K10 processor.
I have been unable to program these virgin boards via the JTAG.
After some investigation it appears that the reset pin is always low.
The reset pin is connected to the 3.3v power rail via a 10K resistor and a 1nF cap to ground.
When the board is powered the reset pin remains low.
I cannot therefore use the JTAG port to program the processor for the very first time since the processor is held in reset.
Is there some other pin that I need to set the state of to bring the processor out of reset?
