I am trying to configure to use GPIO on the P8 header for relay control. I need P8_27 through P8_44. I have successfully disabled HDMI. It seems that if anything is connected to P8_32, the system time loses 5 seconds every minute. I have successfully reconfigured P8_32 to mode 7 for gpio with the same result. I have disabled UART5 with the same result. What could be causing the system time to be running slow? Any help would be greatly appreciated! Thanks!
Another option/question: Are there 16 contiguous gpio pins that are easy to configure for gpio only?
