I'm having an odd problem with a few of the GPIO on my hardware. GPIO 99 and 100 are configured as outputs, OE reg for Bank 4 has the appropriate pins set to 0 to enable them as outputs. Padconf regs have been verified. DATAOUT reg reflects what is written to it. However, the actual pin never seems to change state!? Adjacent GPIO 98 and 101 work fine. Have verified electrical continuity of pins to chip; even reconfigured one of them as in input and DATAIN accurately reflected the state of the pin as we forced it high and low.
This is very confusing (and I know it should be easy). Any ideas?
