AM6442: How to Retrieve Ethernet Link Object

Hiroki Hoshina

Part Number: AM6442

SDK: AM64x Industrial Communications SDK v11.00.00
Reference Sample: EtherNet/IP Adapter Demo
Target Processor: A processor with “E” functionality as described in section 9.1.2 of the JAJSL34G device naming convention
(i.e., supports “D” functionality, with EtherCAT HW accelerator and CAN-FD enabled)
Stack: Third-party EtherNet/IP stack (not the one included in the SDK)

We are using a custom board based on AM64x and the Industrial SDK, and our implementation is based on a sample project provided in response to below question.

AM6442: HWAL_init() and API Usage in EtherNet/IP Adapter Demo - Processors forum - Processors - TI E2E support forums

We are referring to the value corresponding to attribute 4 of the Ethernet Link Object (for example, In Errors or Out Errors).

We could not find a way to retrieve this value.

Could you please advise how to obtain this value?

Thank you.

Hi Hiroki,

you can use IOCTL command to read the statistics, here is a code snippet for Port1:

    ICSS_EMAC_PruStatistics pruStatStruct = {0};
    ICSS_EMAC_IoctlCmd  ioctlParams;
 
    ioctlParams.command =  ICSS_EMAC_IOCTL_STAT_CTRL_GET;
    ioctlParams.ioctlVal = (void *)&pruStatStruct;
    
    ICSS_EMAC_ioctl(icssEmacHandle, ICSS_EMAC_IOCTL_STATS_CTRL, (uint8_t)ICSS_EMAC_PORT_1, (void*)&ioctlParams);

After the call to ICSS_EMAC_ioctl, the pruStatStruct variable would contain the statistic info you need to compose the response for attribute #4.

Best regards,
Pourya

Hi Pourya,

Thank you very much for your clear explanation and the code snippet.

Using ICSS_EMAC_ioctl with ICSS_EMAC_IOCTL_STATS_CTRL worked perfectly for retrieving the statistics needed for Ethernet Link Object.

Your support helped us resolve the issue.

Best regards,

Hiroki
