I have run the simple_socket_server example on ALtera De2_115 board , though my code run's without any error but wont respond to my ping request from other PC it says Host unreachable. i have attached the print screen of run time console of Eclips.
please help me out where i am wrong... regards kaushal29 Replies

I have some updates according to the web server example on the CD. Maybe "kaushal" should look at this example.

But here again as soon as i receive data from remote Board it stop responding to Ping request, The Sequence which i am following on this Current Project is as follows. 1. Porting the Hardware on ESDK_TX board 2. Porting The Software on NIOS-II 3. Board Respond to Ping Request-OK [ping-test-OK.jpg] 4. Send data from NIOS-RX board to This NIOS-TX board 5. Board Stop Responding to Ping Request [Ping Failed after receiving Data.jpg] 6. Re-porting the Software on ESDK Board (During Porting it Stuck at Auto-Negotiation PASSED) [ Stop At Auto-Negotiation PASSED.jpg] 7. Re-try for Re-porting the Software on ESDK Board(During Porting it Stuck at Auto- Negotiation PASSED) 8. Switch OFF the ESDK Board and Then Switch ON the Board, 9. Re-Porting the Hardware on ESDK board 10. Re-Porting The Software on NIOS-II 11. Again Board Respond to Ping Request-OK [Power OFF and ON then Reporting-HW and SW-Ping OK.jpg] 12. Send data from NIOS-RX board to This NIOS-TX board 13. Board Stop Responding to Ping Request So It Seems that as soon as i receive data from remote Board (ESDK-RX), this board stop responding to ping request, and this situation persist till i switch OFF and then switch ON the board and then follow the same procedure again, even re-porting the software (elf file) won't improve the condation.

attached is my sopc file, is priorities which i select is correct...?
i am Using Vectored interrupt controller (VIC) also ....! - Altera_Forum
I post more details about the webserver example. attached is also an image with the current ip-address of the DE2-115-board.

You test every time if edge_capture is set or LPktCount != (PktCount-1) => Busy wait. I'm not use about other tasks, but if your task has highest priority, other tasks (TCP/IP-stack task?) couldn't get CPU time...# define PktSize 640 # define PktCount 460 void SSSSimpleSocketServerTask() { unsigned int LPktCount = 0; unsigned int Count = 0; unsigned int DataCount = 0; printf("\n\t\t----Ready to Receive Synchronous Data----\n"); while (1) { Count = 0; LPktCount = 0; edge_capture = 0; do { if (edge_capture) { edge_capture = 0; // Clear Interrupt IOWR_ALTERA_AVALON_PIO_DATA(TEMP_OUT_BASE, 1); // Send High to Test Pin TEMP_OUT ImgBuff = IORD_ALTERA_AVALON_PIO_DATA(DATA_BASE); // Read Data from RS422 Port Count++; } if (Count == PktSize) { // check end of packet-data Count = 0; // Point to Start of packet data LPktCount++; // Increment packet Count } IOWR_ALTERA_AVALON_PIO_DATA(TEMP_OUT_BASE, 0); // Send LOW to Test Pin TEMP_OUT } while (LPktCount != (PktCount-1)); } - Altera_Forum
Are you sure that your ImgBuff table is big enough? How did you define/allocate it?
I've never used the VIC but are you sure you are using the correct procedure to use it in your software? I think it is a bit different than the regular interrupt system.
