我按照你的方法修改了设备树,并且阻断了 外部PHY的时钟输入。
网卡芯片运作有异常,如下:
[ 1065.457596] stmmac_hw_setup: DMA engine initialization failed
[ 1065.458125] stmmac_open: Hw setup failed
[ 1065.730336] stmmac_hw_setup: DMA engine initialization failed
[ 1065.730873] stmmac_open: Hw setup failed
[ 1065.861226] stmmac_hw_setup: DMA engine initialization failed
[ 1065.861762] stmmac_open: Hw setup failed
[ 1076.026827] stmmac_hw_setup: DMA engine initialization failed
[ 1076.027365] stmmac_open: Hw setup failed
[ 1143.430365] stmmac_hw_setup: DMA engine initialization failed
[ 1143.430903] stmmac_open: Hw setup failed
[ 1143.558241] stmmac_hw_setup: DMA engine initialization failed
[ 1143.558772] stmmac_open: Hw setup failed
应该是时钟的问题
