PMOD GPIOs are configured in iWave provided deliverable available fom the FTP link. In this design, the AXI GPIO IP is connected to the Zynq UltraScale+ MPSoC IP.
In G35D dev kit, two PMOD connectors, each providing 8 GPIO (8-bit width).
The AXI GPIO base address is 0x8008_0000 in the design . The PMOD GPIO numbers range from 397 to 412.
Use the below commands in the Linux kernel to toggle the GPIOs and make sure to use the correct pin numbers as configured in the design. For reference, commands are provided based on G35M/G35D design.
Example :
echo 397> /sys/class/gpio/export
cat /sys/class/gpio/gpio397/direction
echo out > /sys/class/gpio/gpio397/direction
echo 1 > /sys/class/gpio/gpio397/value
