TDA4VM: how to use use spi0 and spi1 in the driver of SPI_DEV in linux

Part Number: TDA4VM

hi TI

I have the following questions on TDA4VM SPI:

  • How to enable SPI instances of TDA4VM?
  • How to enable SPIDEV on TD4VM SDK?

I want to usb spi0 and spi1  in the driver of SPI_DEV in linux

  • the spi mode is slave

  • Hi,

    Please refer the application note: https://www.ti.com/lit/pdf/sprad26?keyMatch=DRA821

    Regards,
    Keerthy

  • dmas = <&main_udmap 0xc610>, <&main_udmap 0x4610>;

    how to set the dma about spi0 and spi1,what is the meaning 0f '0xc610'

  • this is I add the code:

  • Hi Zhao,

    Some of the PSIL thread numbers for SPI0/1 are missing:

    So please add below change:

    Also main_spi0 node should be as below:

    +       main_spi0: spi@2100000 {
    +               compatible = "ti,am654-mcspi", "ti,omap4-mcspi";

    +               dma-names = "tx0", "rx0";
    +       };

    And dmas properties for main_spi1 will be

    +               dmas = <&main_udmap 0xc604>, <&main_udmap 0x4604>;
    +               dma-names = "tx0", "rx0";

    Best Regards,

  • My modifications are the same as yours, but transfer failed in tx and rx.

    I also test zhe spi4 and mcu spi2,but transfer failed.
