  • How do I convert the Web Server HTML files of the AX110xx uIP TCP/IP Stack sample code into C files?

    AX110xx uIP TCP/IP Stack sample code v1.0.4 already includes the HTTP Web Server source code inside. Please make sure the web page HTML files are put into the "SRC/WEB/FS" subdirectory of the uIP sample code and run the "mkfs.exe" command in the "SRC/WEB" subdirectory. The "mkfs.exe" command will convert these HTML files into the FSDATA.C and FSDATA.H files. AX110xx uIP TCP/IP Stack project file (ax11000.Uv2) will include these two files (FSDATA.C and FSDATA.H) to compile the runtime code.

  • How many TCP socket connections are supported by AX110xx uIP TCP/IP stack?

    The TCP socket connection count is dependent on the RAM size on the AX110xx platforms.

  • How do I assign a static IP address for the AX110xx Ethernet Boot Loader?

    You don't need to assign a static IP address for AX110xx Ethernet Boot Loader, the AX110xx Ethernet Boot Loader will always get an IP address from the DHCP server.

  • How to open the gerber files of AX110xx development boards?

    You can open the gerber files of AX110xx development boards by running ORACLE's AutoVue Evaluation Revision tool (30 days evaluation date). Please visit ORACLE's web site for more details.
