Gene, Here is an unofficial site <http://unofficialpi.org/Distros/RealtimePi/nightly/> for raspberry pi systems. Take a look at: http://unofficialpi.org/Distros/RealtimePi/nightly/2018-11-06_2018-10-09-realtimepi-stretch-lite-0.4.0.zip <http://unofficialpi.org/Distros/RealtimePi/nightly/2018-11-06_2018-10-09-realtimepi-stretch-lite-0.4.0.zip> http://unofficialpi.org/Distros/RealtimePi/nightly/2018-11-06_realtimepi-kernel-4.14.74.tar.gz <http://unofficialpi.org/Distros/RealtimePi/nightly/2018-11-06_realtimepi-kernel-4.14.74.tar.gz> http://unofficialpi.org/Distros/RealtimePi/nightly/2018-11-06_2018-10-09-realtimepi-stretch-lite-0.4.0.zip.md5 <http://unofficialpi.org/Distros/RealtimePi/nightly/2018-11-06_2018-10-09-realtimepi-stretch-lite-0.4.0.zip.md5>
I believe this stuff is all 32bit. Yeah, the Pine64 group is much smaller than the raspberry pi group. I bought a Pine64 A64+ during the kickstarter campaign. I have it running a vanilla kernel and I have never succeeded in getting the LCD screen that I bought with it working. One of the guys over at machinekit got it working on a pine64. Personally, I wish I had waited, I really like the features of the RockPro64 (4gb ram, USB3.0, and gigabit ethernet. I may buy one of them to play with and see if I can get preempt-rt working. For me I hate the fact that the ethernet runs on the USB bus. Do you have a picture of how you connected the rpi3b SPI to the 7i90HD?
