Sheraz Posted June 10, 2021 Share Posted June 10, 2021 I have UART1 enabled on MIO 48() 49(). I can't figure out where these pins are on the board. Please help me out in finding the relevant part from the documentation. Attached is the screenshot from schematic found at: - https://reference.digilentinc.com/_media/reference/programmable-logic/arty-z7/arty_z7_sch.pdf Any help is highly appreciated. Its my first post.

zygot Posted June 10, 2021 Share Posted June 10, 2021 Well, as you can see those pins are not connected to anything. Some ZYNQ based FPGA boards have a PMOD or other connector connected to unused PS_MIO pins but your board doesn't. If you need a second UART you can export the unused PS UART to the PL though the EMIO and either connect the pins to PL logic or PL GPIO. JA or JB seem to be your only options for your board.
