Someone need to port LwIP to ll_temac core/wrapper?

Hi,

I'm evaluating one option to transmit images over Gigabit Ethernet. The most efficient is the GSRD desing with the Treck TCP/IP stack using jumbo frames, but the Treck stack is not free and I'm thinking in others TCP/IP stacks like LwIP. If LwIP or uIP can support jumbo frames I would like to use them.

Another question is the device utilization grade of the temac design (79% of slices!!). There is no space enough for another sistems in the ML403 board, I will open one discussion about this.

Thanks

Marco, I want it too!

I would also like to have a decent reference design for Virtex-4FX12 (ML403) which we all know it has lots of good hardware included (PPC and EMAC hardware cores), but the problem is size (since FX12 is the smallest of FX series). The new reference design should include: compact (one core if possible) and lightweight hard TEMAC core (probably Local Link - LL) with sizable FIFOs (to tune the core according to required performance and available BRAM) and open source lwIP stack (to avoid licensing).

I hope that we get enough interest in this topic,

Hello, I opened a webcase about it. Only plb_temac will support lwip and we can use it when edk sp2 will be released.

Now GSRD team has developed a MPMC 2 which is very customizable.

As soon as sp2 will be released I will test a system based on plb_temac and mpmc 2 controller.

Yes, it would be great to have temac used by either lwip or Xilnet. As of now, we cant use the hard-core MAC just because of this reason.

Hi Marco

What about the MPMC 2 component? Do you know if the GSRD has been updated?

Regards

Hi David, I'm still waiting that GSRD team will port lwip to plb_temac. It will be available into EDK 8.2 release (not 8.1.2).

Hi boys, good news!!

The GSRD team will be release a new version of the GSRD using the MPMC2 at the end of May.

I'm waiting that impatiently

Best regards
