有没有办法为100 Mbps精确配置STM32MP MAC？

139 Mac

问答对人有帮助，内容完整，我也想知道答案 0 我们想使用 STM32MP 和以太网物理层 LAN8720 (10/100 Mbps) 构建我们自己的电路板。似乎内核在启动时识别以太网 phy 并将其配置为 100 Mbps 全双工。 [ 2.907461] stm32-dwmac 5800a000.ethernet: IRQ eth_lpi not found [ 2.912172] stm32-dwmac 5800a000.ethernet: PTP uses main clock [ 2.917902] stm32-dwmac 5800a000.ethernet: no reset control found [ 2.923940] stm32-dwmac 5800a000.ethernet: No phy clock provided...

答案对人有帮助，有参考价值 0 我假设您检查了 HW 和 RJ45 接线和电缆。请检查设备树 eth1_pins_mx pin4，似乎是“bias-disable; drive-push-pull; slew-rate = <1>;” 缺少，因为 TX_EN 是 STM32MP1 的输出。
