I too need to have the HDMI output not blank out, and am having problems.
Using the link that you provided, I did the following:
- I went to */media/BEAGLEBONE* where */dev/mmcblk0p1* was mounted.
- I edited *uEnv.txt* changing it from:
*optargs=quiet drm.debug=7*
to
*optargs=quiet drm.debug=7 consoleblank=0*
then rebooted the system. To my dismay, after ten minutes, the HDMI output
still blanked out.
*(I also tried adding consoleblank=0 with double quotes around it as shown
in the provided link, but no luck.)*
I did discover that the other part of information from that link does work.
When SSHed into the BBB, issuing this command:
* echo 0 > /sys/class/graphics/fb0/blank *
does take turn the HDMI output back on.
Did I do something wrong with that consoleblank=0 line in uEnv.txt? I also
tried adding it to the uEnv.txt file in the /boot partition.
Thanks,
Jim
