For what it is worth, and in case this might help. The screen resolution / bitdepth I mentioned in uEnv.txt is a kernel parameter. So if you happen across a post or article that mentions kernel params for screen resolution, etc. uEnv.txt is how the uboot passes kernel params to the kernel.
Or maybe I just confused the situation more ? Example, examining /boot/uEnv.txt: ... cmdline=quiet init=/lib/systemd/systemd ... cmdline= is where one would pass kernel parameters to the kernel. Using uboot on the beaglebone black. On Fri, Jul 10, 2015 at 2:09 PM, William Hermans <[email protected]> wrote: > *I have been searching for a few days now.
