Hi,
As has probably been stated before, the Starterware script UARTPinMuxSetup(x) doesn't support pins other than UART0 and UART1. After looking through the AM335X documentation, we can see that whilst there is an offset for conf_uart0_rxd, conf_uart1_rxd, etc etc. there doesn't appear to be one for UART4 (or for 2,3 and 5) which is why the script doesn't work past UART1. However I read in another post that conf_mii1_rxd3/txd3 can be used to enable UART3. However, if this is true, there is no conf_mii1_rxd4/txd4 for UART4 for example. Thus looking at the offsets in the Control Module it isn't immediately obvious how to enable UART4, and I can't find anything in Starterware which gives pointers as to how to do this. Therefore, what is the method for setting up the multiplexing for UART4?
Thanks
Phil
