Hi..I am using NIOS II Small CPU at 125MHz frequency & ram size is 128MB. I have tried with -O2 optimization but didn't see any difference in performance. In the callback function first I am calling tse_mac_rcv() and then after checking for chain complete mask & status tse_mac_axRead() is called which inside calls do_async_transfer(). After that I am putting my logic for received packet. Is this the correct way to handle ISR callback? With this configuration my ISR callback is called max upto 250-300 times in a second and which indicates the maximum speed we can achieve to 250-300KBPS. Is there any other way we can handle these logic? I have not tried with multiple chain desciptor.

    Hi..

    Am using Quartus version 21.1 for FPGA programming and software development for NIOS II SDK Tool. Am working on TSE ethernet. we have added TSE IP in Quartus and BSP files got generated to NIOS Tool , but i could not find these functions like tse_mac_rcv() , tse_mac_axRead() , tse_mac_raw_send().

    can you please send the files which consists of these functions .
