Unforch and after many try's, I can't get it to reboot when installed, sorta, on an rpi4b. I say sorta, because no matter how many times I rebuild it, the build does not generate an arch/arm/boot/dts/overlays directory. The build itself is error free. The raspi kernel build instructions from their somewhat dated wiki also say to use the bcm2711_defconfig, but it does not now exist in a git clone. And a hwinfo of the rpi4b says I should use the bcm2835_defconfig for a starter .config. Is there any hope of making this work? I have been using a 4.19 rt-preempt I built on a rpi4 running buster, driving 3/4 ton of 75 yo Sheldon lathe, and now I'm trying to help a guy at the west end of the country rig an rpi4b to run a good sized cinci mill. The pi4 has more than enough power to run LinuxCNC. Thanks for any guidance. Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
