w5500的包不带有rt_hw_spi_device_attach对spi设备进行注册，所以会提示找不到设备：

添加如下代码可对spi设备进行自动绑定。
#include "drv_spi.h"
int w5500_spi_device_init()
{
__HAL_RCC_GPIOA_CLK_ENABLE();
return rt_hw_spi_device_attach("spi2", "spi20", GPIOA, GPIO_PIN_12);
}
INIT_DEVICE_EXPORT(w5500_spi_device_init);
emm……传输错误……

在board.c中添加spi初始化函数：
void HAL_SPI_MspInit(SPI_HandleTypeDef* hspi)
{
GPIO_InitTypeDef GPIO_InitStruct = {0};
if(hspi->Instance==SPI1)
{
/* USER CODE BEGIN SPI1_MspInit 0 */
/* USER CODE END SPI1_MspInit 0 */
/* Peripheral clock enable */
__HAL_RCC_SPI1_CLK_ENABLE();
__HAL_RCC_GPIOA_CLK_ENABLE();
/**SPI1 GPIO Configuration
PA5 ------> SPI1_SCK
PA6 ------> SPI1_MISO
PA7 ------> SPI1_MOSI
*/
GPIO_InitStruct.Pin = GPIO_PIN_5|GPIO_PIN_7;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
GPIO_InitStruct.Pin = GPIO_PIN_6;
GPIO_InitStruct.Mode = GPIO_MODE_INPUT;
GPIO_InitStruct.Pull = GPIO_NOPULL;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
/* USER CODE BEGIN SPI1_MspInit 1 */
/* USER CODE END SPI1_MspInit 1 */
}
else if(hspi->Instance==SPI2)
{
/* USER CODE BEGIN SPI2_MspInit 0 */
/* USER CODE END SPI2_MspInit 0 */
/* Peripheral clock enable */
__HAL_RCC_SPI2_CLK_ENABLE();
__HAL_RCC_GPIOB_CLK_ENABLE();
/**SPI2 GPIO Configuration
PB13 ------> SPI2_SCK
PB14 ------> SPI2_MISO
PB15 ------> SPI2_MOSI
*/
GPIO_InitStruct.Pin = GPIO_PIN_13|GPIO_PIN_15;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
GPIO_InitStruct.Pin = GPIO_PIN_14;
GPIO_InitStruct.Mode = GPIO_MODE_INPUT;
GPIO_InitStruct.Pull = GPIO_NOPULL;
HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
/* USER CODE BEGIN SPI2_MspInit 1 */
/* USER CODE END SPI2_MspInit 1 */
}
}
又有了进展……

[E/wiz] WIZnet chip configure initialize timeout.
[E/wiz] RT-Thread WIZnet package (V2.0.0) initialize failed(-2).
找到对应输出代码：
/* initialize WIZnet chip configures */
static int wiz_chip_cfg_init(void)
{
rt_tick_t start_tick, now_tick;
uint8_t phy_status;
uint8_t memsize[CW_INIT_MODE][CW_INIT_SOCKETS] = { 0 };
/* reset WIZnet chip internal PHY, configures PHY mode. */
if (ctlwizchip(CW_INIT_WIZCHIP, (void*) memsize) == -1)
{
LOG_E("WIZCHIP initialize failed.");
return -RT_ERROR;
}
start_tick = rt_tick_get();
do
{
now_tick = rt_tick_get();
if (now_tick - start_tick > CW_INIT_TIMEOUT)
{
LOG_E("WIZnet chip configure initialize timeout.");
return -RT_ETIMEOUT;
}
/* waiting for link status online */
if (ctlwizchip(CW_GET_PHYLINK, (void*) &phy_status) == -1)
{
LOG_E("Unknown PHY Link stauts.");
}
rt_thread_mdelay(100);
} while (phy_status == PHY_LINK_OFF);
return RT_EOK;
}
发现是连接超时，插上网线，禁用DHCP，设置好IP，复位，初始化成功,此时电脑可以ping通W5500，尝试w5500 ping电脑：
