Tool/software:

In the example enet_cpsw_est_am243x-evm_r5fss0-0_freertos_ti-arm-clang, I want to change it to press T to send 160 packets, so I change the ENETAPP_TEST_TX_PKT_CNT to 160U, but the serial port printing result is as follows

Invalid option, try again...

CPSW EST Test Menu:
EST control list tests:
'T' - Send test packets from host port
'1' - Set admin list #1 (stretch)
'2' - Set admin list #2 (truncate)
'3' - Set admin list #3 (guard band)
'4' - Set admin list #4 (single priority)
'5' - Set admin list #5 (admin basetime in future)
'6' - Set admin list #6 (unsupported list - new cycle time)
'7' - Set admin list #7 (unsupported list - too small interval)
'8' - Set admin list #8 (invalid list - zero length)
'9' - Set admin list #9 (invalid list - zero interval)
EST state:
'E' - Set EST state to 'ENABLE'
'D' - Set EST state to 'DISABLE'

    Hi QianQian Huang,

    The current application's send logic works such that it only sends the maximum number of tx packets allocated to the application through sysconfig. This can be modified to send more packets, but I would like to understand the target of the experiment. This example is meant to be just a demonstration of the capability of EST, and a simple self test. If you want to do multiple submits for self test, it would not exactly line up with the default self test checks. You can follow the application's documentation for enabling the same.

    If you would ike to develop an application on top of it, we suggest you update the send logic to handle continuous packet streams rather than single burst of load. 

    Please let us know if you need any further clarification or support regarding this.

    Thanks and regards,
    Teja.
