  1. Sorry, on my /boot there is dtb.img, i just made a mistake in my comment here. The thing is I don't know for what are those child-nodes, googling didn't gave me clear answer.
  2. 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? }; reserved-memory { #address-cells = <0x00000002>; #size-cells = <0x00000002>; ranges; linux,secmon { compatible = "amlogic, aml_secmon_memory"; reg = <0x00000000 0x10000000 0x00000000 0x00200000>; no-map; linux,phandle = <0x0000000a>; phandle = <0x0000000a>; }; linux,secos { status = "disable"; compatible = "amlogic, aml_secos_memory"; reg = <0x00000000 0x05300000 0x00000000 0x02000000>; no-map; }; aml_pstore { compatible = "amlogic, pstore"; reg = <0x00000000 0x07300000 0x00000000 0x00100000>; no-map; }; linux,meson-fb { compatible = "amlogic, fb-memory"; reg = <0x00000000 0x7e000000 0x00000000 0x02000000>; no-map; linux,phandle = <0x0000002c>; phandle = <0x0000002c>; }; linux,di { compatible = "amlogic, di-mem"; size = <0x00000000 0x01e00000>; linux,phandle = <0x00000033>; phandle = <0x00000033>; }; linux,chunk-reserve { compatible = "amlogic, chunk-reserve"; size = <0x00000000 0x04000000>; linux,phandle = <0x0000002b>; phandle = <0x0000002b>; }; linux,ion-dev { compatible = "amlogic, idev-mem"; size = <0x00000000 0x03000000>; linux,phandle = <0x00000030>; phandle = <0x00000030>; }; linux,vdin1_cma { compatible = "shared-dma-pool"; reusable; size = <0x00000000 0x01000000>; alignment = <0x00000000 0x00400000>; linux,phandle = <0x00000034>; phandle = <0x00000034>; }; linux,ppmgr { compatible = "shared-dma-pool"; size = <0x00000000 0x00000000>; linux,phandle = <0x00000032>; phandle = <0x00000032>; }; linux,codec_mm_cma { compatible = "shared-dma-pool"; reusable; size = <0x00000000 0x15000000>; alignment = <0x00000000 0x00400000>; linux,contiguous-region; linux,phandle = <0x0000002d>; phandle = <0x0000002d>; }; linux,picdec { compatible = "shared-dma-pool"; reusable; size = <0x00000000 0x00000000>; alignment = <0x00000000 0x00000000>; linux,contiguous-region; linux,phandle = <0x00000031>; phandle = <0x00000031>; }; linux,codec_mm_reserved { compatible = "amlogic, codec-mm-reserved"; size = <0x00000000 0x04100000>; alignment = <0x00000000 0x00100000>; linux,phandle = <0x0000002e>; phandle = <0x0000002e>; };
