AM3517 - Use of UART4_TX/RX At Same Time as GPMC

Other Parts Discussed in Thread: AM3517

Hello,

  We need four UARTs (no modem control necessary, just RX and TX) in our application using the AM3517. We are using the GPMC to interface with an FPGA. We'll be operating the GPMC in synchronous multiplexed Address/Data mode but we won't require the use of the WAIT signals. Since we're not using GPMC_WAIT1 or GPMC_WAIT2, will UART4_TX and UART4_RX still be available even though we're using the rest of the GPMC interface?

 

Thanks,
John M.

  • John:

    Yes you can do that.  UART4_TX & UART4_RX are muxed to two additional locations in the pin mux map as well.

    GPMC_CONFIG1 has bit to specify not to use wait monitoring.

    This tool is available to help with pin muxing:
