Ping Fail on QSPI Write

Vishakh M11

Hi,


We are using Am437X custom platform running VxWorks.

When we try to ping the board during QSPI write/read operation in progress, pinging stops and will continue once the write operation is over.

Is there any dependency between QSPI and cpsw0(RGMII)?

Regards,

Vishakh

    From a quick read of the AM437x documentation I can't find any mention of a dependency between QSPI and cpsw0 at the hardware level.

    I don't know which version of VxWorks is in use, but from memory of VxWorks 5 the tNetTask runs by default at priority 50 and if the tNetTask task is blocked by higher priority tasks then the network activity will stall.

    Is the SQPI read/write done in a task which is a higher or lower task priority than the tNetTask or other tasks required for network communication?
