Dear MShro1,

Thank you for using this Intel Community.

You are able to know where your data from Ethernet is being stored by your mSGDMA configuration. In other word, based on your configuration in the mSGDMA (e.g: where to Read and Write data from) should tell you where is the data located in the SDRAM.

Hello NAli1_Intel,

Thank you very much for your reply and the Intel Support. Much appreciated.

A quick follow up on your reply: I am having a little difficulty in finding the exact address of the mSGDMA read/write in the simple socket example shipped with NIOS II (Quartus version 18). I do note that the altera_avalon_tse.c file does contain the initialization and set up for the tx and rx mSGDMAs, but I am unable to find the exact address.

Would appreciate your help.

Thanks once again.
