Help building a new Android Firmware with every port all functional, please :D

HiarkVictor

Hello there my orange users, I don't have much time, so I'll be fast for this thread, guys I wanna build a fully functional Android, but I need to activate all it devices (I2C, UART, maybe SIM Card, TV exit, absolutely everything), so I was wondering, any ideas? For example, I have my own custom FEX working pretty well with the stock firmware, but this one never let me control the SPI ports (I activate them in the configuration, and "spidev" or any other device like that never appears), so I assume the problem is coming from the kernel, so I will try to build my own Android firmware.

So please, any help could be thankful for example:
- If you know where a good Orange Pi Android source, that could be pretty useful.
- Maybe, you know how to activate all that devices in my existing stock Android, that could be awesome too, because I wouldn't have to start all my work again.
- Or if you know everything posibly useful at all of this topics, please comment it here, that could be an awesome help too.

First, thanks for your time guys, and second, honestly I love my Orange Pi, is so different to any other device (for example, the now really super common Raspberrys), so honestly guys, I wanna help with this community and grow with my Orange Pi, if you know something I'd be thankful and maybe I know some answers if you have a problem too, so please, let's grow together and make this an awesome project! Cheers!!!
