  1. I am trying to use the PmodCAN module together with PetaLinux on the ZedBoard, to display a CAN interface within the OS. So far I can make it show up in the interface overview with the following device tree overlay: /* <petalinux-project-root>/project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi */ /include/ "system-conf.dtsi" / { osc: can_osc { compatible = "fixed-clock"; #clock-cells = <0>; clock-frequency = <20000000>; }; }; &gpio0 { #interrupt-cells = <2>; interrupt-controller; }; &
  2. Hi, I am currently working with the PmodCAN module and I am trying to make it work inside a bigger design with other AXI IPs. Unfortunately I can not find any documentation about the PmodCAN Vivado IP and the AXI address space. So I have some questions: 1. It is not clear to me, what the use case of the `AXI_LITE_GPIO` interface is. From what I can see, the PMOD interface is pre-defined to be used for the SPI communication with the MCP25625 IC; other SPI PMODS doesn't seem to need it either. I have the suspicion that some of the MCP25625 Pins can be configured as GPIOs in some way,
