No plain v4.9 or the > gen3-sdio branch from my tree? I have not tried cloning your tree. I am using the Rasperry Pi kernel source https://github.com/raspberrypi/linux which is v4.9.29 I checked out the last commit you made to the mainline then cross compiled the driver from within the Rpi tree, copied the module over to the Pi and insmod'd it. To debug I was making code changes on my desktop, re cross compiling the module and scp'ing it over (then rmmod'ing and insmod'ing the new module). I'll try using a vanilla 4.9 kernel, and if that fails I'll try cloning your tree. Thanks for getting back to me. Will report my progress. thanks, Tobin. _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
