BobA:

They are obviously not usb gamepads for the reason you stated.  They are not recognized as such when plugged into a PC and the documentation makes mention of a proprietary interface for increased speed and responsiveness. No need for more electronics to figure out that they are not USB. :D

Xtreme2k:

I have both a gamebox and a logic analyzer, but analyzing the gamepad will not lead anywhere. Just as BobA said, it's for sure not USB but probably some kind of serial protocol, which I probably could reverse engineer but it would not really help us.

What we need to do is get the machine booting from either USB or SD card. For booting from SD card, we would need to get Pin 93 to GND. At first I assumed that this pin is not connected at all and just put to VCC by the CPUs internal pullup. However, when I managed to solder a cable to it and connect it to GND, I blow one of the fuses next to the power connector - obviously the pin is connected to VCC somewhere under the CPU and so I did a short-circuit, I should have checked that before. This makes it hard to get the pin down to GND.

The other option is to get the CPU into USB booting mode. To do that, Pins UART_TX and ADIN1 have to be altered. UART_TX is accessible on a test pad on the board, I guess that ADIN1 also has to be accessible somewhere because USB booting is probably how the system is programmed at the factory, but I have not yet found it. As soon as it's in USB booting mode, it should be detected as a usb device by the PC and we would be able to access it with the driver and tools provided by Ingenic.

I think they're more interested in just finding the solution.  Whether anyone plans on using that information to use one of these inside a project of theirs depends probably on how difficult it would be to recreate the process to get the product to work "correctly."

Looks like the boys in SA have figured out how to get it into USB boot mode.....

For those that can't read it, basically they've bridged a few points on the MOBO and are running the unit off a powered hub.  They're able to control booting with it but haven't gotten a dump of the ROM yet.  There is speculation on if the OS is MINIOS.

Awesome. Say, is it possible to have this output to RGBS instead of that Composite output?
