Installation & Boot
Flash the .img onto the SD card with Balenaetcher.
Open the SD card and modify the uEnv.txt file and create u-boot.ext from other files as follows.
Insert the SD card into the TV box slot, insert a toothpick into the AV hole connector and press the switch inside while holding it down.
Connect the power connector until you see T95 Max+ twice; after the second time the logo appears, remove the toothpick.
Tested DTS Files
In the boot partition, open the uEnv.txt file.
Edit: FDT=/dtb/amlogic/meson-sm1-sei610.dtb
Replace it with your preferred .dtb file.
meson-sm1-sei610.dtb: WIFI OK, ETH OK
meson-sm1-tx3-bz.dtb (from Tanix TX3 100Mbit 2.1Ghz): WIFI OK, ETH OK
meson-sm1-tx3-bz-oc.dtb (Tanix TX3 100Mbit – OC to 2.2Ghz): WIFI OK, ETH OK
meson-sm1-tx3-qz-oc.dtb (Tanix TX3 1Gbit – OC to 2.2Ghz): NO ETH working
meson-sm1-sei610-ethfix.dtb: NO ETH working
meson-sm1-sei610-x96maxplus.dtb: NO ETH working
Mainline u-boot
When you run the “neofetch” command, you will see 3.336MB of RAM, so to obtain 3.8GB (4GB – GPU memory),
in the boot partition of the SD card, there is no u-boot.ext file,
so rename u-boot-tx3-bz.bin to u-boot.ext.
u-boot-tx3-bz.bin shows 3.8GB of RAM.
u-boot-s905x2-s922 will not BOOT
try other u-boot-xxxxx
