hi, 

i tried enc module but froze on "wainting for ip"

dhcp on router is on, works fine on other pc, i tried set static ip but server not working

Any thoughts?

That sounds a bit strange. As the Silicon Revision is reported correctly, the MISO/MOSI and CLK lines are ok. Is the interrupt line correctly connected? It's supposed to be on PE4.

Are you using the lwIP or the uIP version?

I'm working with latest copy of your lwIP branch and running into some trouble.

I'm getting a Hard Fault when trying to call the netif_add() function.  I've tried both static and dhcp configurations, but no luck.  I'm going to try digging deeper but was wondering/hoping you had ran into it and knew a quick fix.

 

Thanks!

Interessting. I haven't experienced that. If you could provide me with either the binary ELF file or the output of "objdump -d" run on the ELF file I will try and see if I can figure out what goes wrong.

 

Cheers,

Maybe a stupid question. Is there a wizzard guide how to build this? I installed stellisware, works very fine, installed the gnu tools and what must I next??

[jalder 0]

Sure, attached is the main.elf.  Be warned, it's pretty messy and riddled with snippets testing the LED ports and printf's from stepping through the program to see if it was indeed the netif_add() function.

 

Thanks again!

 

So, from what I've gathered with online resources, I'm thinking it is a stack/heap memory issue.  I've tried adjusting the stack in startup_gcc as well as adjusting the memory variable in the lwip.opts without much luck.  Not sure offhand what the last compiled combination that elf I've attached used.

Does the output from your Hard Fault handler come from the ELF file you sent? 

 

I'll try to run flash the ELF file tonight and see if I can figure out what is happening.

[xpg 127]

Jalder, I tried out your ELF file and tried to see if I could figure out what went wrong, but couldn't seem to get anywhere within the short time I had available.

If you are willing to share the source code with me I'll try to have a second look at it.

Have you made any changes to the code? Which compiler are you using?

[soccou 1]

No changes to the code, just the toolchainsettings.

 

Ubuntu 12.04 with gcc 4.6.3

 

[edit]

oh, I guess you mean the arm compiler, i installed per the directions from here the summon toolchain

Yes, the ARM compiler. I will try to reproduce this.

Ok, I just figured this one out. You have set SERIALPROG=1 in toolchainsettings, which seems reasonable. However, when doing that the Makefile I am using is using a wrong linker script (both Makefile and linker script are borrowed from http://teholabs.com/). Try set SERIALPROG=0 again, and you should get a nice resulting main.bin, which you will need to flash yourself using lm4flash.

I apologize for the confusion.

 

Cheers,

Paul

  awesome, it compiles now. and i was able to flash it.

thanks for taking your time to check into this for me.

 

now on to checking wiring of the enc28j60 and see if i can get connectivity.

[soccou 1]

hmm, well as is typical for me. one mountain crossed another on the horizon looms.

 

so I got the programmed flashed and running, with the ETH chip wired up. Now I am getting a hard fault like jalder

 

@jalder did you ever make any progress on that error?

 

here is a capture of the output, i added a print statement is the only change to the code

so i am guessing it get's lost somewhere in here

 printf("netif setup\n");
  netif_add(&netif, &ipaddr, &netmask, &gw, NULL, enc28j60_init, ethernet_input);
  netif_set_default(&netif);
  netif_set_up(&netif);
  printf("netif done\n");
