    Hello, i'm confused with the UART0 pins i'm not receiving any data ,i'm using 800x480 display ,5-Inch ,i'm not able to receive any data on the UART0 ,as per schematic my transmiter and receiver pins are 37 and 36 ,but not getting any data also on the board back side it is written as IO44 and IO43 but in the schematic it turns out to be ground
    Please reply asap
