DRA72XEVM: Access to I2C and SPI pins on DRA7x EVM Jacinto 6 ES1.0

Mustafa Ozcelikors

Part Number: DRA72XEVM

Hello,
I want to use I2C and SPI communication in my DRA7xEVM Jacinto 6 ES1.0 board.
Looking at the schematics, I am unable to see any pin header that exposes SPI or I2C interfaces.
Is there something I am missing?

Any guidance is greately appreciated.

Hi Mustafa,

No dedicated I2C /SPI headers on the EVM. You could get some of the I2Cs and SPIs via wire soldering or re-using some of the other connectors.

For example I would try

SPI[2]_CS[0]n

on connector EXP_P3 , pins 1,3, 2, 4. and not connecting anything else to these pins

For I2C3, you could use EXP_P1 pins 1 and 3. Would be good to check for already used addresses by other slaves so you choose a free one.

SoC pinmux settings may or may not be needed in both cases.

Regards,

Stan

One more question, Does Jacinto 6 ES 1.0 have I2S that I can use to plug in my Radio Tuner module?
Thanks again.

Hi Mustafa,

Sorry for delay. Jacinto SoCs include peripheral(s) called MCASP - Multi-Channel Audio Serial Port which can be configured for I2S.

Stan
