Hi, how are you? Well, I don't know English very well, so this text will be translated using Google Translate since I'm Brazilian. Anyway. I found a way to boot the SD card with Linux on the Allwinner H3 chip, using a Chinese MXQ 4K 5G TV box. I booted Android normally and, using the remote control, pressed the power button and then confirmed. After shutting down, I booted with the remote control and Linux started normally. After that, every time I booted with the SD card, it booted perfectly. Another thing I did before, but I believe it doesn't affect this, was to enable USB0 device mode in developer mode. I hope this information helps with your Linux projects!

I really hope that Armbian will be released soon for this board. I have it, but the official ISO has an old kernel and no RT capability.

your sbc has only 100mbit nic

Hi. My download speed is so low over ethernet. Speed must be 19Mb/sec, but real speed is 7-8Mb/sec. download speed on armbian download speed without armbian Tell me what is my problem?

The puzzle seems to have resolved itself. I gave up and shut the printer off about 04:00 this morning and went to bed. Got back up, powered it on about 08:30, and its all working, updating 304 pkgs right now. It was rebooted at least 15 times as I worked last night w/o any affect. What the hell is the diff between a reboot and a full powerdown of 4+ hours??? Did dd-wrt flush its cache of MAC addresses? IDK. But w/o a global net, I was trapped, I could not DL the tools needed to troubleshoot. A very frustrating state of affairs. I do not see anyplace where I could mark this as solved.
