Hi everyone,

I run the simple socket server example, and I got the error as below.

Full message error is :

dtrap - needs breakpoint

panic: pktdemux: got null pkt

ip_exit: calling func 0x400f814

netclose: closing iface Altera TSE MAC ethernet

ip_exit: calling func 0x401321c

Anyone could help? Thanks in advance.

Regards,

What version of the tools are you running? Are you just doing the regular Simple Socket Server example or have you modified it?

Hi,

I am using version 8.0.

I think rcvd queue was corrupted.... what should I do?

Thanks

Do you have access to a newer version of the tools? I think the TSE MAC driver and NicheStack were in a bit of a state of flux in 8.0. Specifically it seems that in 8.0 they still had hard-coded paths in the TSE MAC driver for the SGDMA controllers. As such, I think you can receive this error if you haven't named the components in your SoPC system exactly like they are named in the reference design.

Hi,

What do u mean by hard-coded paths in the TSE MAC driver for the SGDMA controller?

I am using the design example inside the installation path. Could u pls specify which components i need to rename correctly?

Thanks a lot

If you are using the design example from the installation path, then the names should be correct. In which case your problem is different. Would you care to post your project here?
