AM3354: Ethernet package drop issue

Tony Tang
Mastermind 29092 points
Part Number: AM3354

AM3354+KSZ8042RNL RMII, made several batch boards, most boards have Ethernet stability issue. 

ND board: 8pcs boards, 5 good, 2 have ping time out issue, 1pcs Ethernet doesn't work.

NC board： 12pcs boards. 5 good, others have ping time out issue, occasionally can pin through.

On 1 pcs NC bad board: change the serial terminal resistor from 33ohm to 49.9ohm, Ethernet works. 

Do same on one bad ND board, Ethernet stablity issue improved. ping 64byte always successes, ping 1600byte package, occasionally time out.

Jump i.MX board MAC to bad NC AM3354 board KSZ8041 PHY, Ethernet on i.MX works. 

Jump i.MX board MAC to bad ND AM3354 board KSZ8041 PHY, Ethernet on i.MX works. 

Jump bad AM335x board MAC to i.MX board KSZ8041 PHY, Ethernet on AM3354 doesn't work.

Some NC bad board, power cycle many times, Ethernet can work normally occasionally, power cycle again, Ethernet doesn't work again.

Schematic and layout, signal captures in attached file.

1362.AM335x RMII signal capture.docx

Did loop back test result as below:

  • MAC loop back: no error, no drop 
  • PHY loop back: TX 3 package, RX 2 good, 1 CRC error.
  • Set local board PHY to remote loop back mode, ping from remote board to local board, statistic on remote board, TX=RX package, no error.

Please help advise.

    Hi,

    Please attach the console log like the RMII signal capture doc with the following in the log:

    - Complete boot sequence, we need to see the mdio bus and cpsw initialize

    - ethtool eth0

    - ethtool -S eth0

    - perform the network commands such as if you are adding a static ip address, 

    - after the ping command please do this command again ethtool -S eth0

    - please describe what NC board and ND baord refers to in this post 

    Which SDK is being used here in this use case. 

    Typically CRC errors are HW related. 

    Best Regards,

    Schuyler

    ND and NC are Board model numbers.

    Startup logs and ping tests between two machines, record as two files:log_NC.log log_ND.log.

    During ping testing, the ND10 machine first ping the NC6 machine with three packets. NC6 encountered Rx CRC Errors: 3, as following figure：

    Then NC6 pings ND10 with three packets, and NC6 Rx CRC Errors increases to 5, as this figure：

    The network condition is unstable: there is chance of pinging 16KB packet on the same board, with packet loss rate of 0, and sometimes ping 32 bytes, with packet loss rate of 100%.
