Evaluation license for SiTCP

ixiotidi

Hi,
I am writing in order to ask if there is to test the SiTCP core without purchasing a full license. I am interested in trying to see if I can access a single device and check if I can send/receive data. If this is possible do you have any guidance on how to make the setup? (e.g. what IP address is being used, etc.)
Thanks

Hi Ioannis!

I am writing in order to ask if there is to test the SiTCP core without purchasing a full license.

Yes, it is possible.

I am interested in trying to see if I can access a single device and check if I can send/receive data.

Connecting to a single SiTCP device in a closed network is in accordance with BBT's policy of providing free samples.
Some NetList and Sample files are available from BBT's GitHub.

If this is possible do you have any guidance on how to make the setup (e.g. what IP address is being used, etc.)?

The following documents may be of help to you

Hi,
thanks for the useful information. So I managed to have the core implemented in my test board however I am experiencing some odd behaviour. I have set a default IP address in a point to point connection. When I ping I get a valid reply although from the ping sequence I can see that some packets are lost:
--- 192.168.10.16 ping statistics ---
16 packets transmitted, 8 received, 50% packet loss, time 14999ms
I configured the ethernet core from Xilinx to operate at 1Gbps with BaseX only (since this is what is supported by my SFP module) and am running the SiTCP core at 200MHz from a derived from the default 125Mhz clock in my board. I have disabled Auto-Negotiation (didn't manage to make it work with AN included). Is there anything I can cross check, or are you aware of such a behaviour? Thanks in advance
Cheers

Hi Ioannis!

Not particularly, but I'm sure you can understand from the samples.
