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

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.

    regards,

    Stan
