That might require the parport. rpspi.ko ONLY runs on a pi-3b. From the rpspi.ko to a mesa 7i90 with 3 7i42TA's gives you more stuff and gpio's than is needed, 72 pgio's total. I've got gpio using gingerbread in my hal file and gui's and still have 15 or more gpio's unused. And the pi is still loafing. > Worst case I use a genuine Pi 3 with the flash update to boot from > external HDD (no more SDcard drama) > > What say the hive mind? > > Greg > > ---------------------------------------------------------------------- >-------- Check out the vibrant tech community on one of the world's > most engaging tech sites, Slashdot.org! http://sdm.link/slashdot > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
