STM32H743VGT6 与RTL8211E-VB使用MII Full Duplex Only模式无法正常工作
2024-06-14
您好: 我现在使用的RTL8211E-VB的PHY芯片,,PHY芯片的数据手册中明确表示了,ETH_TX_CLK信号是需要由单片机产生。如下图所示: 而STM32H743VGT6单片机在HAL_ETH_Init函数中会在下面这段代码中返回错误: /* Wait for software reset */ while (READ_BIT(heth->Instance->DMAMR, ETH_DMAMR_SWR) > 0U) { if (((HAL_GetTi...
