ti-linux-kernel的cpsw驱动不支持fixed-link 当前SDK版本是2.00.01.07 我们使用了一个micrel的switch芯片,用spi管理,没有使用mdio 当前版本的cpsw是依赖mdio的,尝试dts中增加了fixed-link,但cpsw.c仍然提示 Missing mdio platform device 网上搜到,似乎这是一个bug,在4.4内核上已经有了补丁,不过用不到4.1的cpsw...
1. I use the CPSW mdio/mdc interface to access the Marvell switch 88E6131. I define the MDIO/MDC clock is 5MHz. When I read the registers in switch, most time it returns correct value, some time it is wrong value, some time it is 0xFFFF. What setting I should adjust to make this...

Hi, In the StarterWare CPSW Wiki ( http://processors.wiki.ti.com/index.php/StarterWare_CPSW ) it is written, that enough delay shall be given to ensure the successful
2能接收到,说明接收描述符的配置是正确的吧?至少配置的大方向应该没错吧?目前我是测试,不区分数据,只要路由器或者路由器连接的PC有数据发出来,都会被CPSW统计到。 我的数据发送,目前在AM3359的千兆网寄存器CPSW_CPDMA的DMA状态寄存器DMASTATUS中没有任何报错,发送完数据中断状态寄存器的标志位都能被置位,所以我觉得...
MDIO i2329 — MDIO: MDIO interface corruption (CPSW and PRU-ICSS) Bhargav Medamanuri 说: If you think it might help solve the issue, Can you please provide software workaround for this? There is a manual mode that is implemented in the linux vs the state change mode. ...
本公司设计的板卡有两路网口,一路是千兆的以太网,使用网卡芯片KSZ9031接到ARM4377的rgmii1接口上,mdio_clk和mdio_data分别连接B17和A17使用CPSW驱动,该网口能正常工作。 另一路是PRU的网络使用网卡芯片TLK105L接到ARM4377的pru1_mii1接口上,dio_clk和mdio_data分别连接A12和B12使用prueth驱动,在系统启动后无法识别...
