Greetings all; I have attempted to build a newer kernel, several times, kernel srcs based of links to as new as 4.19.50-rt22, the latest announced on the linux-rt mailing list, but all the makefiles use tools-master's mkimage to assemble the compressed u-boot image.
Putting it as mildly as I can: Thats a right pain in th ass. The unpacked download of tools-master is close to a gigabyte and hasn't but one functioning Makefile, which does not build a callable or installable mkimage. The mkimage directory in this nearly a gig of data contains an 800+ byte .py file that apparently assembles the also present in that directory files that account for the initial 8k LOADADDR offset. I suppose the thing could be used by writing a script, putting it in the $PATH and making it a python executable but there is absolutely zero guidance on how to go about this, and my knowledge of python is very limited. So now I have stumbled over RealtimePi from github, which uses any raspian.zip file as a src file, and processes it with vagrant to build a new, write it to the u-sd card, image that boots to a realtime system. Supposedly. Now see if I can collect enough stuff to make that work, as I found the latest raspian-stretch is only a couple moths old. And it doesn't say if it will actually run on the pi. So I think I'll try it first on this machine. But I have a personal preference to building pi stuff on the pi. So we'll experiment a bit. And post results as I have 2 spare, clean 64GB u-sd's on hand. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
