Xilinx FPGA User IO Access From Petalinux

how to find the led values in zedboard

Hi. How your design is working without interrupts signals from AXI Uartlite?

[@AustinParks]

It took me forever to find this video! Thanks so much. This is much better than libmetal / openAMP. The xparameters.h headers aren't reconfigured unless you build petalinux w/ --sdk option which takes forever. (granted you can still manually copy the address from vivado instead of using definitions in xparameters.h) But this method is actually portable, doesn't rely on xilinx from (the user-space side), so it'll be my new goto way of accessing gpios. Why's it so hard to figure out how to read / write more than one bit at a time via sysfs? Only Xilinx knows I reckon... Now I can finally get my midi project up and going (Whoop!): kzbin.info/www/bejne/d2eTn5d_rph8pK8

Can you share the source code of the example? Thanks a lot
