TDA4VM: Configuring Slave works, but during the test I get Kernel error.

Hi there,

I have successfully created a slave SPI device using the device tree with these settings:

in /psdkla/board-support/linux-4.19.94+gitAUTOINC+5a23bc00e0-g5a23bc00e0/arch/arm64/boot/dts/ti/k3-j721e-common-proc-board.dts

        };
};

In /psdkla/board-support/linux-4.19.94+gitAUTOINC+5a23bc00e0-g5a23bc00e0/arch/arm64/boot/dts/ti/k3-j721e-main.dtsi

                #address-cells = <1>;
                #size-cells = <0>;
        };

But sending data or connecting to it using the Linux spidev_test I get the following error:

A help from TI would be nice, so I can find out what is not working, If I am guessing correctly the Memory Areas are configured wrongly.

Thanks a lot

    Hi,

    The issue is seen with which SPI interface? main_spi3 or main_spi6?
    Could you share the full Kernel log from boot time?

    Regards,
    Vishal

    Dear Vishal,

    Thanks for the reply

    The issue happens with main_spi6 (Which is added as slave here):

    root@j7-evm:~# du -ah /sys/class/spi_slave/     
    0    /sys/class/spi_slave/spi3
    0    /sys/class/spi_slave/

    The whole kernel log / journalctl I added as attachments.

    Regards,

    Pouyan

    Hi,

    I see a mismatch in dts configuration of main_spi6. You have configured pinmux for CS1, but you have slave configured as CS0 ( reg = <0>;) 

    If slave is on CS1, then set: reg = <1>;
    If slave is on CS0, then pinmux is wrong and should configure SPI6_CS0 pin instead.

    Dear Vishal

    I changed the reg=<1> but I still get the same kernel OOPS:

    Can you try removing the "spi-slave-time" from the compatible field?

    Is main_spi3 functional?

    Also, you have configured main_spi6 with property spi-slave.
    You have other threads for slave mode --> https://e2e.ti.com/support/processors/f/791/t/889123 and https://e2e.ti.com/support/processors/f/791/t/886252

    Could you combine them all in to one.

    Hi Vishal,

    thanks for the responses:

    About the other threads I marked them as solved because at the moment I dont see any Kernel errors upon booting and the DTS files are compiled correctly.

    I tried your first suggestion for the main_spi6 which is as you correctly suggested is the slave and the result is the same kernel error. (removing the spi-slave-time).

    For your question about the main_spi3: The main_spi3 responds accordingly with zeros because it is not connected to any slave, The idea was to connect the created slave main_spi6 main_spi3 master so I can have a loop and test the SPI capabilites and my own code. But the spidev_test application dont show any Kernel OOPS when i use the spi_main3 only zeros because it is not connected to anywhere.

    Hi Pouyan,

    Can you clarify to me what you're trying to set up right now, and what issue you're seeing with it? Is the issue trying to connect main_spi6 (as slave) and main_spi3 (as master) to each other, and message between them? 

    As a note, our Linux SDK does not support or test SPI slave capabilities.

    Thanks,

    David

    Dear David,

    yes thats the idea. I want to connect the spi6 to spi3 (Using GESI) and Transfer Messages between them. SPI Master as far as I know works but connecting to SPI slave give me the Kernel Errors you see. I think your note probably make it more clear. Is it in your ROADMAP to support SPI Slave in LinuxSDK?

    Best regards,

    Pouyan

    Hi Pouyan,

    One suggestion is that DMA is required to support SPI slave mode, so you could try adding something like

    dmas = <&main_udmap &pdma_main_misc_g3 0 UDMA_DIR_TX>,
                            <&main_udmap &pdma_main_misc_g3 0 UDMA_DIR_RX>;
    dma-names = "tx0", "rx0";

    to the main_spi6 node.

    I'm looking into our roadmap support for now. 

    Can you also provide a full boot log and the commands you're using after enabling the DMA?

    Thanks,

    David
