    32bit Slave FIFO + UART + GPIO_SPI_lines

    esakkiraja.p_2282511

      hi all,

       

      I have use 32 bit slave fifo and I want to use GPIO[53:56] as an GPIO used as spi lines for read/write to SPI flash externally connected to a board. And also I need to use Uart for printing debug messages.  In FX3, when using 32 bit gpif, then SPI_MOSI and UART_TX are mapped to the same GPIO[55]. Is it possible to use both UART and GPIO in GPIO[55] at a time ?. I tried by reconfiguring the IO matrix, but it wont work. Is there any possible way to do this?

       

       

      Thanks in advance.
