enable adin1110 on cn0575 using nucleo_l4r5zi

Question

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 jnb22 ,

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.

Regards,
Ali
