I´m trying to control some GPIOs from Petalinux User Space by using /dev/mem-Mapping. I found this tutorial which gives a good C-Code example: http://www.wiki.xilinx.com/Linux+User+Mode+Pseudo+Driver.
Now I´m wondering how to program the PL to get the Linux-modified registers written to the hardware IO´s... Is there a Vivado Example or a documentation anywhere?
Kind regards, wne
What exactly are you asking here :-)
Does this help, there is example code here:
