We have a custom board with 4GB memory.
The output of HDMI and eDP port are both 3840x1080. (each split to 2x ports so there would be connected to 4 1920x1080 monitors).
When we play video for long time, there would be X server crash.
Then we found this thread in forum:
As #18 solution,
We modify boot arguments in /etc/extlinux/extlinux.conf:
add ‘video=tegrafb’ and modify ‘mem=’ changed from ‘mem=2015M@2048M’ to ‘mem=1862M@2048M’
This seems to fix the issue, but we have some questions:
- what does “tegra_fbmem=32899072@0xad012000” mean in #18 solution.
Since the TK1 board is with 2GB memory,
How should we determine the value for our board with 4GB memory?
- What is your advise on this fix, will there be any negative impact?
