AM2432: Create a local network without disable firewall

Hi  Nilabh Anand,

 I  Connect a ethernet cable to the AM243X-LP from host PC .If our customers use it the same way， may it be necessary to close the firewall? The article mentioned that sometimes it is necessary to disable the firewall when creating a network with a router, and did not mention Connecting a ethernet cable to the AM243X-LP from host PC. Is it possible to Connect a ethernet cable to the AM243X-LP from host PC  the firewamay also require to be closed? If that's the case, is there a way for the Ethernet program on the AM243 to avoid the firewall without the need for customers to disable 。

Can you tell me are you using static ip or DHCP mode?

If you are running some DHCP server on your PC then it is not necessary to disable firewall.

HI Nilabh Anand,

I am using DHCP mode， but static IP will be enabled later ，Do I need to disable the firewall to enable static IP? How to avoid the firewall without the need for customers to disable it??

     I have tried it on my end but I do not see the requirement on my end to disable the firewall.

    Which document are you looking at? Please provide it to me

2.Nilabh Anand said ：

   Is customer facing some issue? If yes, please ask them to try static ip mode.

   What do you mean is that static mode does not require closing the firewall？

3.Regarding AM243X, Do you have a document analyzing the LWIP TCP Server code? Please provide it to me。 is there a guidance document for generating some  peripheral code through the sysconfig tool, including the generation of Ethernet TCP code? Please provide it to me.

                                                                                                                                                                                                                                Thanks！

Yes that should be the case.

We have the LWIP TCP server example present in SDK at: https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/EXAMPLES_ENET_LWIP_CPSW_TCPSERVER.html

Please refer to example code located at  mcu_plus_sdk_am243x_08_06_00_38/examples/networking/lwip/enet_cpsw_tcpserver

HI,Nilabh Anand

About mcu_plus_sdk_am243x_08_06_00_38/ examples/networking/lwip/enet_cpsw_tcpserver， How to Enable Static Mode?How to modify a static IP address？

e2e.ti.com/.../am2434 -cpsw-dual-mac-mode   ，我看到一个关于enet_lwip_cpsw的例子，但是我需要的是enet_cpsw_tcpserver，我们需要一个以太网端口作为服务器端或客户端，server mode  is more important
