Thread Summary

                The user encountered issues initializing the ADIN1110 driver on a NUCLEO-L4R5ZI board with an EVAL-CN0575. The solution involved configuring SPI and MDIO settings in prj.conf, including setting CONFIG_SPI_STM32_DMA=y, CONFIG_MDIO=y, CONFIG_ETH_ADIN2111_SPI_CFG0=n, and increasing the system workqueue stack size to 4096. In app.overlay, the SPI and GPIO configurations were adjusted, and spi-oa and spi-oa-protection were commented out. The default EVAL-CN0575 settings (Generic SPI, CRC Disabled) were also considered.

Hi, I have a NUCLEO-L4R5ZI board and a eval_cn0575. I want to enable adin1110 driver for cn0575 on nucleo. I connected nucleo pins to cn575 rpi compatible header as follows:


                                       CN0575 rpi header                                         nucleo


SPI2_SCK                     23                                                                   pb13


SPI2_MOSI                   19                                                                   pb15


SPI2_MISO                   21                                                                   pb14


SPI2_CS                       24                                                                   pb12


SPI_INT                        22                                                                   pb11


RESET_N                    13                                                                    pc13


this is prj.conf:




CONFIG_GPIO=y


CONFIG_SPI=y


CONFIG_NETWORKING=y


CONFIG_NET_L2_ETHERNET=y


CONFIG_ETH_DRIVER=y




CONFIG_ETH_ADIN2111=y


CONFIG_MDIO_ADIN2111=y




CONFIG_SPI_STM32_DMA=y




CONFIG_MDIO_INIT_PRIORITY=81


CONFIG_PHY_INIT_PRIORITY=82




# Enable UART


CONFIG_SERIAL=y




# Console configuration


CONFIG_CONSOLE=y


CONFIG_UART_CONSOLE=y


CONFIG_NET_LOG=y


CONFIG_NET_SHELL=y




# Enable IPv4


CONFIG_NET_IPV4=y


CONFIG_NET_IF_MAX_IPV4_COUNT=2




# Enable IPv6 (if needed)


CONFIG_NET_IPV6=n




CONFIG_LOG_BUFFER_SIZE=8192


CONFIG_SHELL_BACKEND_SERIAL_LOG_MESSAGE_QUEUE_SIZE=256


this is app.overlay




/ {


 aliases {


 adin1110 = &adin1110;


 };


};




&spi2 {


 pinctrl-0 = <&spi2_sck_pb13 &spi2_miso_pb14 &spi2_mosi_pb15>;


 pinctrl-names = "default";


 cs-gpios = <&gpiob 12 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;


 dmas = <&dmamux1 2 13 (STM32_DMA_MEMORY_TO_PERIPH | STM32_DMA_MEM_INC |


 STM32_DMA_MEM_8BITS | STM32_DMA_PERIPH_8BITS)>,


 <&dmamux1 3 12 (STM32_DMA_PERIPH_TO_MEMORY | STM32_DMA_MEM_INC |


 STM32_DMA_MEM_8BITS | STM32_DMA_PERIPH_8BITS)>;


 dma-names = "tx", "rx";


 status = "okay";




 adin1110: adin1110@0 {


 compatible = "adi,adin1110";


 reg = <0x0>;


 spi-max-frequency = <25000000>;


 int-gpios = <&gpiob 11 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;


 reset-gpios = <&gpioc 13p GPIO_ACTIVE_LOW>;


 status = "okay";




 port1 {


 local-mac-address = [ 00 E0 22 FE DA C8 ];


 };


 mdio {


 compatible = "adi,adin2111-mdio";


 #address-cells = <1>;


 #size-cells = <0>;




 ethernet-phy@1 {


 reg = <0x1>;


 compatible = "adi,adin2111-phy";


 };


 };


 };


};




&iwdg {


 status = "okay";


};




&rng {


 status = "okay";


};




&dma1 {


 status = "okay";


};




&dmamux1 {


 status = "okay";


};

this is output
[00:00:00.210,000] <err> eth_adin2111: Failed to communicate over SPI, -5
[00:00:10.410,000] <err> phy_adin: PHY 1 didn't come out of reset, -5
[00:00:10.410,000] <err> eth_adin2111: ADIN adin1110@0 is not ready, can't init port 0 iface


How can I properly use the adin1110 driver for cn0575 using the nucleo board?

    Hi  ,

    I finally managed to resolve my issues and now I can run adin1110 driver on Nucleo_L4RZI.

    I had to use these in prj.conf file:
    

    

    

    

    CONFIG_SPI_STM32_DMA=y
    

    CONFIG_MDIO=y
    

    CONFIG_MDIO_INIT_PRIORITY=81
    

    CONFIG_NET_L2_ETHERNET=y
    

    CONFIG_ETH_DRIVER=y
    

    CONFIG_NET_L2_ETHERNET=y
    

    CONFIG_PHY_INIT_PRIORITY=82
    

    CONFIG_NETWORKING=y
    

    CONFIG_ETH_ADIN2111=y
    

    CONFIG_ETH_ADIN2111_SPI_CFG0=n
    

    

    

    

    # # Enable Heap memory allocation (required for k_malloc and k_free)
    

    CONFIG_HEAP_MEM_POOL_SIZE=4096
    

    CONFIG_MAIN_STACK_SIZE=4096
    

    CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=4096
    

    

    

    These four are very important:
    

    CONFIG_MDIO_INIT_PRIORITY=81
    

    CONFIG_PHY_INIT_PRIORITY=82
    CONFIG_ETH_ADIN2111_SPI_CFG0=n
    

    

    

    

    

    

    

    

    

    CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=4096
    

    

    

    And also I used these in app.overlay:
    

    

    

    / {
    

            aliases {
    

                    adin1110 = &adin1110;
    

            };
    

    };
    

    

    &iwdg {
    

            status = "okay";
    

    };
    

    

    &rng {
    

           status = "okay";
    

    };
    

    

    &dma1 {
    

          status = "okay";
    

    };
    

    

    &dmamux1 {
    

          status = "okay";
    

    };
    

    

    &spi2 {
    

          pinctrl-0 = <&spi2_sck_pb13 &spi2_miso_pb14 &spi2_mosi_pb15>;
    

          pinctrl-names = "default";
    

          cs-gpios = <&gpiob 12 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;
    

          dmas = <&dmamux1 2 13 (STM32_DMA_MEMORY_TO_PERIPH | STM32_DMA_MEM_INC |
    

                                                      STM32_DMA_MEM_8BITS | STM32_DMA_PERIPH_8BITS)>,
    

                       <&dmamux1 3 12 (STM32_DMA_PERIPH_TO_MEMORY | STM32_DMA_MEM_INC |
    

                                                      STM32_DMA_MEM_8BITS | STM32_DMA_PERIPH_8BITS)>;
    

          dma-names = "tx", "rx";
    

          status = "okay";
    

    

          adin1110: adin1110@0 {
    

                    compatible = "adi,adin1110";
    

                    reg = <0x0>;
    

                    spi-max-frequency = <25000000>;
    

                    int-gpios = <&gpiob 11 GPIO_ACTIVE_LOW>;
    

                    reset-gpios = <&gpioc 7 GPIO_ACTIVE_LOW>;
    

                    status = "okay";
    

                    //spi-oa;
    

                    //spi-oa-protection;
    

    

                    port1 {
    

                              local-mac-address = [ 00 E0 22 FE DA 30 ];
    

                    };
    

                    mdio {
    

                             compatible = "adi,adin2111-mdio";
    

                             #address-cells = <1>;
    

                             #size-cells = <0>;
    

    

                             ethernet-phy@1 {
    

                                      reg = <0x1>;
    

                                      compatible = "adi,adin2111-phy";
    

                                      led0-en;
    

                            };
    

                   };
    

          };
    

    };
    

    

    The default config of CN0575 are:
    

    Generic SPI
    CRC Disabled
    

    

    So I needed to make spi-oa and spi-oa-protection commented in app.overlay and CONFIG_ETH_ADIN2111_SPI_CFG0=n in prj.conf
    

    

    Also If CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE is set as default value, the program crashes when we request a ping from local host.

    Ali

    Hi  ,
    

    That's great!
    

    Thanks for documenting the resolution! This will guide others on what to be mindful of when working with a similar setup.
