Part Number: TDA4VM


hi,

我们在sdk 8.4

ti-processor-sdk-rtos-j721e-evm-08_04_00_02中移植phy,phy已经处于linked状态，但是无法获取ip,按如下方法设置静态IP，也无法ping通

我们的phy已在7.3的sdk中将功能调通，升级sdk8。4后出现此问题，pinmux，rgmii mode都是正确的

    抱歉回复晚了，下面是e2e工程师的回复。

    Is the customer able to read/write phy registers?

    If he is able to, can you check the tx and rx error count register in the phy address space if they are incrementing?

     我们可以通过mdio读取到phy, id,且phy显示连接上了，对应的125M　clk也有，但是mac的tx量到波型给phy,phy有波型到mac（接上网线后）

    这里都有波形是吗?

    请看下面e2e工程师的回复。

    Can you share the ethernet controller stats. You can get them by running "ethtool -S eth0" on linux command line.

    Also, We can try the MAC loopback test to ensure the MAC is working correctly or not first.

    To do this, follow the following steps :

    • Read the register at address : 0x46022330
      • you can read a register in linux using command "devmem2 0x46022330"
    • Add 2 to the value read and write it back to the same register
      • you can write to a register in linux using command "devmem2 0x46022330 w ${original value + 2}"

    To test the MAC, run the following commands

    • ethtool -S eth0 | grep good
    • Do a ping for 5-10 seconds
    • ethtool -S eth0 | grep good

    Please share the output of the test with me.

    If this is successful, please try the phy loopback test as well.

    请看下面e2e工程师的回复。

    I am confused now about the setup, I assumed the earlier setup. 

    Can you share a block diagram of the system and different experiments tried and the working and non working links.

    Also, for wherever is not working, can you do a MAC loopback test. You can find steps on how to do the test here.
