Hello. This is a pretty basic question that I've been struggling with. I am trying to communicate with a GPIO pin (ultimately connected to an encoder) from the JE1 MIO Pmod block from a ZedBoard.
From what I've read with tutorials, on the Vivado side, there are no IPs required besides the main Zynq block.
Right now I just want to turn on and off a pin (actuate high to low) in this block (MIO0 - MIO15) so I left the settings in Vivado alone/in the default state and do not have EMIOs enabled (those are only for the PL side, correct?)
(I am following this tutorial: https://forums.xilinx.com/t5/Xcell-Daily-Blog-Archived/Driving-the-Zynq-SoC-s-GPIO-Adam-Taylor-s-MicroZed-Chronicles/ba-p/389611)
For the software in SDK, I am just changing the
#define ledpin [#]
line to be one of the MIO #'s from the block, say 9 for example. However, I haven't been having any luck communicating with any of the pins.
I would appreciate any help if I am setting up the Vivado hardware configuration wrong, or if I am not accessing the JE1 pins correctly. I am completely new to embedded system programming and working with an SoC/FPGA. Thanks!!
