I'm working on a driver that will adapt itself to whatever is in the FPGA (within reason), and automatically export the right HAL pins and functions. The existing configurations (hostmotX-X) rely on the driver knowing exactly what is in the FPGA, hence the need to revise the driver whenever you come up with a new FPGA configuration. > When you say "this is not as fancy as John K's" do you mean that your > configuration is not as fancy as the hostmotXXX configurations which are > in the emc2 cvs trunk? No. My stuff is intended to go beyond (and maybe replace) the hostmot configs. If I understand Peter correctly, his new config would be something like "hostmot5-12". It would probably work with minor revisions to the existing driver. Seb also wrote: > I've been having a look at the emc2-trunk source tree.
