It also includes the necessary logic to identify an interrupt event when the channel input changes. Contribute to Xilinx/linux-xlnx development by creating an account on GitHub. Xilinx Design Tools: Release Notes Guide. For details please refer to - the above This page is intended to give more details on the Xilinx drivers for Linux, such as testing, how to use the drivers, known issues, etc. Open Source Projects. The drivers included in the kernel tree are The official Linux kernel from Xilinx. The AXI GPIO can I followed the xilinx wiki about linux drivers (Linux-GPIO-Driver) in order to control GPIO connected to the PS throught the MIO and EMIO pins. * - Test and fix basic multicast filtering. In current version, you can set and get the value of the IO channel, enable and disable the interrupt, and receive the SIGIO signal if the interrupt is enabled. The GPIO core consists of registers and multiplexers for reading and writing the AXI GPIO channel registers. You will also design a system to include the new IP created for the Xilinx® Zynq® Learn about working with GPIO in embedded Linux, with a particular emphasis on the Zynq-7000 family. Introduction.
