I add the dts , but boot fail Help me! Please.

Why you comment out &gpio0 {...} block in DTS? Without it console (uartlite) non-functional.
After message NET: Registered protocol family ... kernel try enable console=ttyS1 and disable earlycon output.

Just came across this little device. Would it be possible to use the TFT screen to display "anything"?
And it looks like it has a "phone" connection. VOIP capable??

For 15USD it looks like a fun little device.

ElektromAn · August 4, 2017, 3:33pm

Hmm currently busy ..
but it there any source outside china i.e gearbest, dx

skids · August 4, 2017, 7:48pm

I think you'll find there is no opensource driver for the mt7610en side of the wifi.

drbrains · August 5, 2017, 2:03am

More worried about the screen and it looks like it comes with a stylus for input...ordering one just for fun. Could be nice to have some home automation running on it with the "touch" input

drbrains · August 9, 2017, 10:34am

So the new "toy" arrived ... now what to do??

First 2 stupid questions:

Any difference between NAND and the "oldschool“ flash like all my other devices I should know about, or just consider it like "flash" ??

Second, more important: how do I get it to flash / boot only system 2 and/or into safe-mode? Safe-mode probably holding reset while starting?? (I will have a look at the dual-boot feature that is in the making later)
