I am trying to use the Newhaven LCD display but, when attaching the display the pinmux file no longer operates as it does without the display. When trying to use config-pin utility it comes back as pinmux file not found. I am using the latest debian iot image on SD and flash. Below are the responses to some of the previously posted questions for my BBB with the display attached. My end game is to use the display along with UART1, UART4, SPI0 which should have no conflicts with the display pins. Any help on what to do next would be greatly appreciated.
