SPI5 Failed to create device link (0x180) #43

Closed MarioPieschel closed 1 year ago

MarioPieschel commented 1 year ago

I have configured SPI5 in Stm32CubeMX According to buildroot-external-st/docs/stm32cubemx.md I copied the generated code in the folders kernel -> kernel-dts u-boot -> uboot-dts tf-a -> tfa-dts optee-os -> optee-dts

Unfortunately the description is missing, how to compile this.

by guessing: make uboot-rebuild && make optee-rebuild && make linux-rebuild all

Is it correct?

kernel message: [ 0.059031] stm32-sys-bus 5c007000.etzpc: Failed to create device link (0x180) with soc:pinctrl@50002000 [ 0.445547] stm32-sys-bus 5c007000.etzpc: Failed to create device link (0x180) with 50000000.rcc [ 0.468479] stm32-sys-bus 5c007000.etzpc: Failed to create device link (0x180) with soc:pinctrl@50002000

I guess, the clock for SPI5 is not enabled.

My board is the STM32MP135F-DK, MB1635B. With this configuration: st_stm32mp135f_dk_demo_defconfig.

rename it to dk.ico dk.ioc.txt kernel_log_SPI5_Failed.txt

make uboot-rebuild && make optee-os-rebuild && make linux-rebuild all

MarioPieschel commented 1 year ago

to activate the SPI in user space:

Is this correct?

&spi5 { pinctrl-names = "default", "sleep"; pinctrl-0 = <&spi5_pins_a>; pinctrl-1 = <&spi5_sleep_pins_a>; cs-gpios = <&gpioh 11 0>; / PH11 / status = "okay";

    spidev@0 {
            status = "okay";
            compatible = "rohm,dh2228fv";
            /*
            * spidev uses a compatible string 'rohm,fs2228fv' to have the
            * driver create an spi device node. This is just an example,
            * there is not a real device connected on the SPI bus.
            */
            reg = <0>;
            spi-max-frequency = <30000000>;
    };

};

If I try SPI5v configure with openSTLinux I will get a kernel panic. I gess there is the optee-os source code buggy.

Starting kernel ...

make uboot-rebuild && make optee-os-rebuild && make linux-rebuild all

And make arm-trusted-firmware-rebuild but yes it is correct. For your SPI issue, I will point this issue to ST. They will be more experienced to help you with that.

For recompiling the component: make uboot-rebuild && make optee-rebuild && make optee-rebuild && make arm-trusted-firmware-rebuild && make linux-rebuild all

Then flash:

We have detected several issue:

Optee:

U-BOOT: Use the correct pinctrl: spi5_pins_mx: spi5_mx-0 { pins1 { pinmux = <STM32_PINMUX('H', 7, AF6)>, / SPI5_SCK / <STM32_PINMUX('H', 3, AF5)>; / SPI5_MOSI / bias-disable; drive-push-pull; slew-rate = <1>; }; pins2 { pinmux = <STM32_PINMUX('A', 8, AF5)>; / SPI5_MISO / bias-disable; }; };

spi5_sleep_pins_mx: spi5_sleep_mx-0 {
    pins {
        pinmux = <STM32_PINMUX('A', 8, ANALOG)>, /* SPI5_MISO */
                 <STM32_PINMUX('H', 3, ANALOG)>, /* SPI5_MOSI */
                 <STM32_PINMUX('H', 7, ANALOG)>; /* SPI5_SCK */
    };
};

&spi5 { pinctrl-names = "default", "sleep"; pinctrl-0 = <&spi5_pins_mx>; pinctrl-1 = <&spi5_sleep_pins_mx>; status = "okay";

/* USER CODE BEGIN spi5 */
/* USER CODE END spi5 */

};

On Kernel: Use the correct pinctrl + add a valid compatible for spidev spi5_pins_mx: spi5_mx-0 { pins1 { pinmux = <STM32_PINMUX('H', 7, AF6)>, / SPI5_SCK / <STM32_PINMUX('H', 3, AF5)>; / SPI5_MOSI / bias-disable; drive-push-pull; slew-rate = <1>; }; pins2 { pinmux = <STM32_PINMUX('A', 8, AF5)>; / SPI5_MISO / bias-disable; }; };

spi5_sleep_pins_mx: spi5_sleep_mx-0 {
    pins {
        pinmux = <STM32_PINMUX('A', 8, ANALOG)>, /* SPI5_MISO */
                 <STM32_PINMUX('H', 3, ANALOG)>, /* SPI5_MOSI */
                 <STM32_PINMUX('H', 7, ANALOG)>; /* SPI5_SCK */
    };
};

&spi5{ pinctrl-names = "default", "sleep"; pinctrl-0 = <&spi5_pins_mx>; pinctrl-1 = <&spi5_sleep_pins_mx>; cs-gpios = <&gpioh 11 0>; / PH11 / status = "okay"; spidev@0 { status = "okay"; compatible = "linux,spidev"; reg = <0>; spi-max-frequency = <30000000>; }; / USER CODE BEGIN spi5 / / USER CODE END spi5 / };

One time, all the devicetree will be updated: make uboot-rebuild make optee-os-rebuild make arm-trusted-firmware-rebuild (mainly to re-generate the fip.bin) make linux-rebuild all

Then flash:

Thank you very much for the very good help.

But the I have installed the STM32MP1 Distribution Package. According to these instructions: https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package#Building_the_OpenSTLinux_distribution

There is described the way with the bitbake command.

I don't know how to apply the make commands.

make linux-rebuild all make: *** No rule for make target 'linux-rebuild'. Stop. mpieschel@linux-lab-computer:~/st

Do I need to set an environment variable? In which folder(s) do the make commands have to be executed?

I am new to OpenSTLinux.

Thanks a lot!

kmaincent commented 1 year ago

I thinks your are mixing the build systems. The OpenSTLinux descibed in ST Wiki use Yocto build system where in this github we use Buildroot build system. bitbake is a Yocto command, but make linux-rebuild all is for Buildroot. You have to choose which build system you want to use, you can't use both together. cpriouzeau answered you for the Buildroot Build System.

MarioPieschel commented 1 year ago

Yes, sorry.

MarioPieschel commented 1 year ago

Many thanks to cpriouzeau and kmaincent It woks :O)
