Cannot attach a second spi for arria10

[sayhi2008]

Hi,

I’m working on arria10 and have developed my own board to phase with arria 10. I need to enable 2 spi, after following the doc Building Bootloader for Cyclone V and Arria 10 1 with my own hps.xml, quartus version 22.4pro, uboot version 21.04, the board is booted up with only one spi enabled. With some debugging, I find that the default device tree file (socfpga_arria10_socdk.dtsi) only enables 1 spi. So how should I generate the new device tree file, please? based on the doc, from 20.3pro, bsp editor is not used any more. 

Tried change the socfpga_arria10_socdk.dtsi below to enable spi0(spi1 is default from socfpga uboot), but uboot stucked at reset peripherals

"Deasserting all peripheral resets\n"

then reboot again, never goes to linux.

--------------------------------------------

&spi0 {
status = “okay”;
};

&spi1 {
status = “okay”;

    resource-manager@0 {
            compatible = "altr,a10sr";
            reg = <0>;
            spi-max-frequency = <100000>;
            /* low-level active IRQ at GPIO1_5 */
            interrupt-parent = <&portb>;
            interrupts = <5 IRQ_TYPE_LEVEL_LOW>;
            interrupt-controller;
            #interrupt-cells = <2>;

            a10sr_gpio: gpio-controller {
                    compatible = "altr,a10sr-gpio";
                    gpio-controller;
                    #gpio-cells = <2>;
            };

            a10sr_rst: reset-controller {
                    compatible = "altr,a10sr-reset";
                    #reset-cells = <1>;
            };
    };

};

any hints?

Hi,

So you are using a custom board correct?

What are the full list of item changes (DDR, part number, etc) you made from the Arria 10 SoC Dev Kit?

Could you share your full boot logs?

[EBERLAZARE_I_Intel]

Hi,

Any update from your side?

[EBERLAZARE_I_Intel]

Hi,

Please check your Quartus HPS IP settings and the device tree again.

You may need check the differences vs the Dev Kit, and change accordingly to your custom device from the default settings as the GHRD is based of the A10 SoC Dev Kit.

thanks for the help!

I have solved the uboot issue problem by using linux kernel generated dtb files instead of uboot generated one.

and the dtsi file modified below to enable 2 spidev, and seems it works,

&spi0 {
status = "okay";

spidev@0{
compatible = "spidev";
reg = <0>;
spi-max-frequency = <4000000>;
};

};

&spi1 {
status = "okay";

spidev@0{
compatible = "spidev";
reg = <0>;
spi-max-frequency = <4000000>;
};

};

I have check the board /dev with below while didn't have a chance to test.

any comments are welcome, sorry for late feedback.
