Available GPIOs on coming RockPro64

[tllim]

Hello,

I've noticed that PINE64 plan to provide in a couple of month a board based on the rock chip RK3399. Could you post the pins assignment of the 40 pins connector? I'm particularly interested by I2S0 interface signals (ideally I2S0-SDI0, I2S0-SDO0..3, and clocks), I2C and/or SPI.

Thx

We will release the 40 pins GPIO map on end of this month after second rev PCB released. In general, for i2s, i2c, spi, and uart, we try to follow back RPi 40pin definition position.

Thank you for your answer,


However the RPi does not provide a standard pinning which includes I2S. The "standard" audio is managed as an "on board" PWM stream if I understand correctly. Some manufacturers provide audio card etensions. Wolfson (Cirrus Logic) provides a board with 1 stereo input stream and 1 output stereo stream. The HifiBerry has only 1 output stereo stream. My needs are 1 I2S input and at least 1 I2S output, but ideally I would like 4 I2S output (which is what you can get with the I2S #0 RK3399 interface).

Hope you can take into account these needs.
Thx

The RK3399 looks like a lot of pins but able assign for GPIO pins are not many. RK3399 don't have internal audio dac and the i2S0 has been assigned fro on board audio codec. I will take your request into account but not promise able to accommodate.
