The Industrial SDK (ind_comms_sdk_am243x_09_02_00_08) has been reviewed for EOE. The ESL_eoeDemo.c file is present in the SDK EtherCAT slave demo file, but it simply defines the function; it does not provide written functionality.
Additionally, it only has a receive function—it does not include a transmit function. It wasn't really helpful.
Thus, we would like to know the specified functions' functionality and have a complete example of an EOE Send/Receive handler.
Ethernet over EtherCAT (EoE) is typically used for EtherCAT devices with TCP/IP stack since it requires an IP stack for the operation. An EoE implementation example has been provided by utilizing TCP/IP stack that comes with Linux SDK. The documentation related to the EoE implementation can be found at https://software-dl.ti.com/processor-industrial-sw/esd/ind_comms_sdk/am243x/09_02_00_08/docs/am243x/ethercat_slave/_eo_e_page.html. This EoE implementation approach shall be similar for FreeRTOS based EtherCAT devices. The solution for FreeRTOS SDK is not available at this time. The APIs allows for the utilization of alternative TCP/IP stacks such as lwIP. This presents an opportunity for customers to implement a stable solution particularly for a single-core systems.
