The FPGA based LED registers used in the example code are not present in the precompiled hm2 based FPGA bit-files. You will need to use an FPGA design that has these GPIO registers in the FPGA fabric and make sure the FPGA is programmed with that bit file. The easiest way to do this is probably to compile the FPGA design that should be part of the same GHRD demo where you obtained the C code. Once you have a bitfile, the FPGA can be programmed via u-boot, a device-tree overlay file, or a JTAG download cable. The Machinekit image typically uses a device tree overlay, so if you're not manually programming the FPGA it's probably not programmed. If the FPGA is not programmed, or does not respond to the address assigned to the LED registers, you will get a bus error. -- Charles Steinkuehler char...@steinkuehler.net -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
