Re: uClinux and MAC opencore

Altera_Forum · ‎07-20-2005

Dear Sirs:

I am now trying to work with uClinux and MAC opencores but i have the following error when i try to generate the kernel:

include/nios2_system.h:48:2: warning:# warning Could not execute ...scripts/nios2_system.h/OpenCores_Ethernet_MAC.pm. I have seen there is such file and the content is:

package opencores_ethernet_mac;

use base qw(BasicModule);

use strict;

sub required_module_names {

("igor_mac")

}

sub required_class_name {

"opencores_ethernet_mac";

}

sub run {

opencores_ethernet_mac->run2 (@_);

}

1;

Any idea about what is going wronly?.

Thanks

Jorge

Can you send me the system PTF file that you're building the kernel against via e-mail? I'll see if I can reproduce the problem

Hi Jorge, I tried compiling a kernel using the PTF file you provided and I didn't have any problems creating the nios2_system.h file. There were no# warning pre-processor directives within the file.

Could you e-mail me the results of your kernel build using the original "opencores_ethernet_mac.pm" file (instead of using the one that you modified). I need more context surrounding the# warning message that you got.

One other question... Are you using the Opencores.org Ethernet MAC that we provide? Or did you get yours from somewhere else? I only ask because there were some differences in how the opencores_ethernet_mac name was spelled out in your PTF file than from what we provide in our kits.

Hello Ken:

I am afraid i got it from somewhere else not from Microtronix. It works with NIOS II and Lightweight IP and i though it could work with linux.

However, could i test the Microtronix Opencores?. Could you send it to me?.

Regards

Jorge Domingo

You should take a look at our website for more information regarding our Opencores.org EMAC development kit.

Although in all honesty, I don't know if it's the component itself that's causing problems. Were there any other difficulties when you were installing the Nios II Linux Distribution that you can think of?

Hello:

It still looks like a case issue. Try renaming the opencores_ethernet_mac.pm file so that it matches the output you see in your kernel build.

You'll also need to go through the opencores_ethernet_mac.pm file and fix any case issues in there as well... I'm afraid this is as far as I can take this issue. We only guarantee that the opencores emac driver we package up works with our Opencore EMAC package.
