UART, I2S, I2C, SPI peripheral support


#1

Dear RockPi4 developers,

I wonder if there’s any progress on the peripheral support for the RockPi4. It would not just be great to use standard Pi HATs, but more importantly, it would allow embedded developers to use your product in their designs. Instead of having hobbyists buy 1 or 2, you can have companies buying hundreds, maybe even thousands of RockPi4 units. I’m one of those people. Think about it. Let me know once you have device tree overlays in place.

Cheers,

Pieter
