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 –Ioannis ---

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 –Ioannis ---

Not particularly, but I’m sure you can understand from the samples. > **[GitHub - BeeBeansTechnologies/SiTCP\_Sample\_Code\_for\_AC701\_SFP: This is the SiTCP sample source code (SFP version)...](https://github.com/BeeBeansTechnologies/SiTCP_Sample_Code_for_AC701_SFP)** > > This is the SiTCP sample source code (SFP version) for AC701 communication confirmation. > **[GitHub - BeeBeansTechnologies/SiTCP\_Sample\_Code\_for\_KC705\_SFP: This is the SiTCP sample source code (SFP version)...](https://github.com/BeeBeansTechnologies/SiTCP_Sample_Code_for_KC705_SFP)** > > This is the SiTCP sample source code (SFP version) for KC705 communication confirmation. please check it out.
