Honored ContributorProblems with Cyclone IV and DP83848C
Dear all, I've made my own board of Cyclone IV EP4CGX110CF23C7. And i want to make a ethernet module with DP83848C which is surpported by the TSE core.
However, when i have completed my SOPC system and downloaded the nios program, it seems that something wrong happened to my program and i am confused by this problem for several days. When i run my project as NIOSII hardware on NIOS SBT v12.1, the nios ii console displays as following: interniche portable tcp/ip, v3.1copyright 1996-2008 by interniche technologies. all rights reserved.

netinit: calloc failed getting buffer 17
inet startup error: unable to initialize net

dtrap - needs breakpoint
ip_exit: calling func 0x9e7a4 Here are some attachments of my program. PS: 1. I turned off the DHCP and set the board IP address 192.168.1.234. 2. I created the program from the template Simple Socket Server. 3. There is no NAND flash on my board and i set my board MAC address 00:16:36:fc:14:2d

Altera_ForumFrom the calloc error message, it looks like you don't have enough memory for the embedded system. You can try and reduce the number of buffers in ipport.h, increase the size of your onchip_mem, or connect the Nios CPU to an external RAM (if you have one on board).

I followed your advise and the result seems to be better. But when i ping the board with cmd or telnet, there seems to be no connection.

There doesn't seem to be anything wrong from the terminal output. I suggest that you use a network sniffer (such as Wireshark) on the PC you are using to connect to the board, and signaltap on the FPGA to check if anything is coming in or out on the interface with the PHY chip.
- Altera_Forum
I've tried the Wireshark to grab the packets but i failed. It seems no connection between the PC and the FPGA. The attachment is the output of the Wireshark.

From the terminal output is seems that the set IP address is 192.168.1.234, but you are trying to ping 192.168.0.202
- Altera_Forum
No,no,no....I've just changed my ip address to 192.168.0.202 but no changed the terminal result to this thread.
- Altera_Forum
Okay. Your board isn't even answering the first ARP request, so you need to use signaltap to figure out if the ARP request gets on the PHY's rx interface, and if your system answers on the PHY's tx interface.

how did you connect the computer and the FPGA board? if you directly connected them by only one ethernet cable that maybe the problem. You may use a switch.

I'm a beginner in the field of network and i cannot recognize how the ARP request transmitted to the board. Or may i have your email or msn/QQ in order to contact you conveniently. The following is the signaltap screen shot when ping the board.
