Without uboot no Linux will work in your box

You don't have to do nothing different with other images, they just must be compatible with your hardware. I have never seen ethernet or wifi up in this box, so your alone in this. The .dtb file that you use in extlinux.conf is the key for this hardware to work. I use rk3328_rock64.dtb because others seem to work well but in fact your loosing the gpu driver with them. With the correct .dtb file is very likely the net hardware would work, but this is a very dificult task. I use a RTL8812bu usb wifi adapter that is supported in armbian. In case you look for one you must make sure that there is a good linux driver for it. In fact you have a good one near you, because you can use your phone and activate usb tethering, this always works.

Scrooge69 Congratulations, you have seen your box booting You have to use SD+USB ....... nothing more works. With SD+USB unpowered box press reset and power on. Wait 10 seconds and release the reset. I don't have to do that. anymore, because I think after first botting is enable sd-booting. ¿Or maybe when you see the recover of the box? Don't know for sure. You don't have to begin without usb. I wonder if you have an armbian image in the sd card, only boot in the sd card must be present Why don't you use this. I tried yesterday and works for sure. https://yadi.sk/d/GnFmvx9A8ExVDw/ArmbianTV/20201229-legacy/Armbian_21.02.0-trunk_Station-m1_buster_legacy_4.4.213_xfce_desktop.img.xz?w=1

@nightguest My post refers to Superpow Mxq max. I have read in this thread that is not posible to boot with your box. Anyway the u-boot for rock pc can not boot any rk3328 box, including yours. In order to boot the reset button in the sound jack must be pressed with a toothpick while powering. After booting once many boxes can boot later without the reset pressed.

You have to write U-boot in the sd card. In the following link is the one that works for you. https://yadi.sk/d/_rQgn_FosYuW0g/U-BOOT/U-BOOT-ARMBIAN/20201004 Comes from this Balbest150 thread https://forum.armbian.com/topic/12162-single-armbian-image-for-rk-aml-aw-aarch64-armv8/ In the usb drive you write Armbian image. You have them in the above link from Balbes150 for rk3328. I would use buster legacy which works fine in your box and media framework if you want to play video.

@Scrooge69 Your box needs sd to boot with the uboot rock _pc.img and also an usb-drive with the armbian image. This is because the sd card filesystem is not available once uboot has started.
