So the second stage uEnv.txt file should look like this in order for it to
work.
uname_r=3.15.10-bone8
cmdline=quiet init=/lib/systemd/systemd consoleblank=0
I tried both ways, and both ways work. But only one cmdline env variable
needs be set in the second stage uEnv.txt file.
root@arm:~# mount /dev/mmcblk0p1 /media/boot/
root@arm:~# cat /media/boot/uEnv.txt |grep optargs=
optargs=consoleblank=0
root@arm:~# cat /sys/module/kernel/parameters/consoleblank
0
is how i have it set now However, if i remove that line and reboot.
root@arm:~# cat /media/boot/uEnv.txt |grep optargs=
#optargs=consoleblank=0
root@arm:~# reboot

Thats not it, so one more thing that I changed after I switched to using
optargs

**Eyeballs 5lb sledgehammer sitting on a bench across the room**
At this point I used *setterm -blank 0 *just to see what else it ws that i
did, and it did not work. So Moscowbob, you're right, it does not seem to
be working, but did initially for me until i switched to using optargs . .
. This is definitely very annoying however.
