Without defining this signal, the UART lines receive garbage data
when no cable is connected to the J4 USB UART port.
The GPIO9 is enabled in the reference base design along with the
4MA CURRENT_STRENGTH constraint on the UART pins
-change the video memory interfacing from f2h_axi_slave to
f2h_sdram0
- add f2h_sdram1 port as the default interface for converter DMA
- set as default the full HD resolution at 60 FPS (pixel clock 148.5MHz)
- use a second 200MHz(198MHz) clock from the pixel_clk_pll, as DMA source
to destination clock.
