SK-AM62B-P1: DTS for the QCA7000 driver

Part Number: SK-AM62B-P1

Hello,

After modifying the DTS and adding the QCA7000 driver, Linux fails to detect QCA7000 on the SPI bus during boot.

The modified results are as follows:

Output errors:

root@am62xx-evm:~# dmesg | grep spi1

[ 1.526928] qcaspi spi1.0: ver=0.2.7-i, clkspeed=8000000, burst_len=5000, pluggable=0

[ 1.534950] qcaspi spi1.0: Invalid signature (0xFFFF)

[ 1.540113] qcaspi: probe of spi1.0 failed with error -14

The identified problem is that EXP_SPI0_CLK is not generating the expected output during Linux boot.

Is our modification correct, or did we miss anything?

Do you have any suggestions? Looking forward to your reply. Thank you.

I'm glad you looked at the signals to help debug this further. Here's an E2E thread that has a working solution for AM62x SPI0. Can you please check it and see if you can make it work. Perhaps something with the pinmux or the address-cells / size-cells device properties is missing or wrong. https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1263441/sk-am62-no-spi-signals-on-expansion-headers/4783737 Please report back any findings.

Regards, Andreas

Sorry for the late reply. We've tried the methods mentioned above, but it still doesn't work.

Then, we saw this related thread here: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1280645/sk-am64b-spi1-not-working?tisearch=e2e-sitesearch&keymatch=QCA#

Is the spi interrupt configuration correct? Since we have configured (V25) GPMC0_WAIT1.GPIO0_38, GPIO-458 should appear, right?

The thread I pointed to https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1263441/sk-am62-no-spi-signals-on-expansion-headers/4784647#4784647 has a know-good working example. Are you saying you followed all steps exactly, and don't see any signals on the SPI bus when trying to use the spidev_test utility?

Thank you for your reply. We have tested the light bar, it can light up. We can also observe the clock signal. The changes are as follows.

&main_pmx0 {
    ...
    spi1_pins_default: spi1-pins-default {
        pinctrl-single,pins = <
            AM62X_IOPAD(0x01bc, PIN_INPUT, 0) /* (A14) SPI0_CLK */
            AM62X_IOPAD(0x01b4, PIN_INPUT, 0) /* (A13) SPI0_CS0 */
            AM62X_IOPAD(0x01c0, PIN_INPUT, 0) /* (B13) SPI0_D0 */
            AM62X_IOPAD(0x01c4, PIN_INPUT, 0) /* (B14) SPI0_D1 */
        >;
    };
    ...
};

&main_spi0 {
    status = "okay";
    pinctrl-names = "default";
    pinctrl-0 = <&spi1_pins_default>;
    ti,pindir-d0-out-d1-in;
    spidev@0 {
        spi-max-frequency = <6250000>;  /* 6.25 MHz */
        reg = <0>;
        compatible = "rohm,dh2228fv";
    };
};

Later, when we tried to use the same pin to connect the QCA7005, following the modifications as mentioned above, it failed. We don't see the clock signal. The obvious differences are that 'spidev@0' has changed to 'qca7000: ethernet@0', and there are changes in the contents inside.

So your status is still exactly the below?

[    1.540113] qcaspi: probe of spi1.0 failed with error -14

Did you use a logic analyzer to monitor the clock signal during boot?

It looks like the driver is trying to probe the device, and reading back 0xFFFF which often means the SPI signals are not driven/configured correctly. But since you had a clock come out before when experimenting with the spidev device, at a minimum I'd also expect to see a clock here. Try step by step making your device SPI node look more and more like the working device node that you have, and see what specific difference gets you to a working clock signal.

So your status is still exactly the below?

No, we currently see the following error messages.

Did you use a logic analyzer to monitor the clock signal during boot?

Yes, we don't see the clock signal.

Interesting, something changed. Before you had the error of "qcaspi spi1.0: Invalid signature (0xFFFF)". But now the driver is reading 0x0000.

Can you pin down/investigate what configuration (or setup?) change triggered this change?

Thank you for your help, it can work now.

However, we still cannot determine what the problem is. Originally, the QCA7005 was on another board, and we connected it using wires to the SK-AM62B-P1. Now, with our custom board where the QCA7005 is on the board, we have succeeded.

Thank you once again for your assistance.

Best regards,

Leo

I don't understand. Earlier you said you see no clock signal, but now you are saying you succeeded? So this can be closed? If so, can you please share your final device tree changes for reference?

Thanks, Andreas

Yes, this issue can be closed. Below is the final device tree we changed, provided for reference. Thanks.

&main_spi2 {
	status = "okay";
	pinctrl-names = "default";
	pinctrl-0 = <&main_spi2_pins_default>;
//	ti,pindir-d0-out-d1-in;

	qca7000: ethernet@0 {
		reg = <0>;
		compatible = "qca,qca7000";
		pinctrl-names = "default";
		pinctrl-0 = <&main_qcairq_pins_default>;
		interrupt-parent = <&main_gpio1>;
		interrupts = <10 IRQ_TYPE_EDGE_RISING>;
		spi-cpha;
		spi-cpol;
		spi-max-frequency = <8000000>;
		local-mac-address = [ A0 B0 C0 D0 E0 F0 ];
		status = "okay";
	};
};

Best regards,

Leo
