And I am missing mkimage to build the uImage needed for an rpi-3b on the rpi-3b. I have downloaded and unpacked tools-master.zip which does contain a mkimage directory. Looks like this: pi@picnc:/media/pi/workpi1/linux-rt-devel-4.16.18-rt9 $ ls -l ../tools-master/mkimage total 48 -rw-r--r-- 1 pi pi 157 Jan 12 2018 args-uncompressed.txt -rw-r--r-- 1 pi pi 201 Jan 12 2018 boot-uncompressed.txt -rw-r--r-- 1 pi pi 32768 Jan 12 2018 first32k.bin -rwxr-xr-x 1 pi pi 822 Jan 12 2018 imagetool-uncompressed.py -rw-r--r-- 1 pi pi 343 Jan 12 2018 README Where this is sitting is a long ways away from the rpi's $PATH. And you can paint me bright green, never haveing attempted anything like this. So what I am considering is composing a bash script named mkimage that is in $PATH, to exec python /media/pi/workpi1/tools-master/mkimage/imagetool-uncompressed.py with the path to the (z)image file as its argument. What I am unsure of is how to specify the output path so as to put the output file back into the kernel build tree so that a "make deb-pkg" can find it. So I could sure use some guidance. Since this Makefile dates from 2002, is there a patch for it that will eliminate this bit of tom-foolery with a bash script? I'm trying to do this on raspian stretch installed on the rpi-3b. Thank you all. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
