There are lots of things that can go wrong with the SoC+FPGA systems. I suggest first trying to manually load the hostmot2 driver and verify everything works as expected. If the FPGA and HAL driver are working properly, they will communicate with each other and the HAL driver will instantiate driver code for the logic it finds in the FPGA. That said, it looks like you've got the hm2 capture-position function commented in your HAL file if I'm looking at the right one: https://github.com/cmcquinn/Hm2-soc_FDM/blob/master/Snickerdoodle/HAL/Replicookie/Replicookie.hal#L73 ...that will break all the hm2 code and generate following errors. -- 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.
