Hello
I have Mecool M8S Pro+ with broken emmc, because Android no longer boots, but that's not a real problem.
I want to free gpu-reserved memory to run headless armbian.
I placed img.dtb on /boot, but system is using another one, maybe from Emmc, so, to get my current .dtb file:
dtc -I fs -O dts /proc/device-tree/ -o current.dts
Now I wan't to free reserved memory using s905_autoscript.
On pages 2 and 3 of this topic I saw command in autoscript to remove entire reserved-memory node, but that caused instability:
fdt addr 0x1000000; if test "${nographics}" = "1"; then fdt rm /reserved-memory; fdt rm /aocec; fi
There is also removal of /aocec node, i think it's related to HDMI but I'm not sure.
Anyway which one of child-nodes from reserved-memory should I remove/disable to free gpu-reserved memory?
