AM437x ethernetip_adapter demo for standard TCP/IP

Other Parts Discussed in Thread: SYSBIOS

Hi,

I use sysbios_ind_sdk_2.1.0.1 and AM437x IDK EVM.

I want to use the PRU-ICSS for standard TCP/IP. The Idk 2.1 provided an example of ethernetip_adapter which is based on the TCP/IP. So I planned to reuse the ethernetip_adapter for my work. However, after analysing the code, I couldn't find how the NDK transfers the packets data to Ethernet/IP stack which is provided by Molex.

There is an function void processProtocolFrames(uint32_t* queue_number, void* userArg) in icss_eip_driver.c but it just addresses the PTP and DLR frames. I didn't find the project calling any socket related APIs.

Thanks.

Sincerely yours,

Qinghai

Hi,

All socket related calls are done from Molex stack user layer. This is not released as a part of ISDK.

Please refer to NDK User guide and Reference guide for more details

Thanks for you reply, Prajith.

Molex stack user layer is the interface provided by user_xxx.h ? I read the NDK API guide.
I think there should be some hook function or call socket related functions to listening on the port. I don't find the interface through which NDK pass the data to EIP.

Qinghai

Hi Qinghai,

Regret to inform you that the Socket related codes (Ethernet/IP and Profinet) are not available to public in the ISDK release. For reference, please download NSP package which can be found in NDK Download link . You can adopt the socket API to work with examples in ISDK.

Regards,

Prajith

Thank you, Prajith.
I have solved it with the NDK APIs. But I met another problem e2e.ti.com/.../446528
Thanks.
