Igor Mac, DP83848 and tcpdump

Hi all, 

 

could you somebody advice me with my problem ?  

I have design (in attachement) - NIOS2, SDRAM, ethernet (igor mac) with zImage and when i boot kernel and use ifconfig eth0 192.168.2.2 and use ping, it is ok. 

But when i ping to my pc (ping 192.168.2.200) it finished with 100% loss packet and NIOS2 dont read data ok - when i read ifconfig statistics - all reading packet are dropped. In wireshark i read arp packet, pc answer, but uclinux send again arp packet, because dont read packet well and try it again. 

Setting of dp83848 looks ok - the same like in development kit, where it works. 

When i see this on oscilloscope, it looks ok. Where could be error ? on design or on the board ?  

Does anybody build tcpdump or some another tool for reading arp packet ?  

 

Thank you very much.

You can build tcpdump for Nios II. It's included in uClinux-dist. You can (may need to) update it to the latest version by extracting the source in user/tcpdump/tcpdump-4.x.x and changing the Makefile to point to that version.

When i turn on  

[*] tcpdump and use make, it finished with these mesagges:

But the main question is - if i have error on design - sopc builder or schematic design in Quartus ... or is there any errors on the board - with DP83848 etc. ?  

 

Thanks for your opinions.

If you mean the compile error -- it's not related to the FPGA/SOPC design. You should be able to build any of the user applications and libraries regardless of of the FPGA design. 

 

If you mean your actual problem -- yes it's very likely it's the design, but if you are not using the latest version from Linux "nios2" branch then it could likely also be the software. I don't know anything about the Igor MAC though.

Thank you, 

but yesterday I finally found the error - it was in SOPC builder in Open Cores 10/100 Ethernet MAC Avalon - Igor Mac, which has 3 parameters: 

Total descriptors: 128 

TX Fifo size in bytes: 128 

RX Fifo size in bytes: 4096 

 

It must be 4096, when it was 128, data was not read.  

 

Although i didn´t make tcpdump, i change open_eth.c to debug mode and in this mode the kernel print RX and TX data from/to ethernet chip. (in attachment)
