Thats not going to happen if I can help it, spi is working quite well on the pi3's. Bertho has it working on the pi4's he thinks but I'm the only one running that hardware so its up to me to prove it. But my push right now is to get the new, 40x faster video available in later stretch, working with lcnc on the pi3. I can't touch buster because of the wayland virus. Once thats done, then putting in the pi4 with only the hm2_rpspi.so update should get it working with the pi4. One step at a time IOW. The pi4 is powered up, and theoreticly all I have to do is change the default rt defconfig from a bm2709 to a bcm2711, build and install. Theoretically... Damn thats a big word ;-) Thanks Alexander. > [1] https://github.com/raspberrypi/linux Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
