Adafruit's simple library is free and quick to setup. GPIO[0] would be routed to IO 54, GPIO[1] to IO 55, and so on. They works in uio in petalinux. Issue 287 Petalinux, MicroBlaze and Ethernet. The green line is driven from the input port which, in our design, will be connected to the emulated clock - which is the same as the one used for the MicroBlaze SoC subsystem. PYNQ also supports the Xilinx Alveo accelerator boards and AWS-F1. So if GPIO is routed through the EMIO, the numbering needs to be offset by 54 when writing software. Based on the description in page 13 of zedboard user guide here, we know that UART 1 is already connected to the PS part of device which means there will be no connection from PL part to. The General Purpose I/O driver resides in the gpio subdirectory. This will create the project, you can then build using petalinux-build, but since we are going to customize PL we need to do a few steps before.
