Adding TCP/IP to AVB

isaacdavis · Post by **isaacdavis** » Tue Aug 04, 2015 6:02 pm

Hello,

I am developing on the xCORE 200 Multichannel Audio Platform. I am currently running the example program "Gigabit Ethernet AVB endpoint example using TDM master," documented here:

https://www.xmos.com/download/private/A ... rc1%29.pdf

and am trying to add TCP/IP functionality to the program using this documentation:

https://www.xmos.com/download/private/A ... rc3%29.pdf

as a guide. However, the above TCP/IP example is written using version 3.2.1 of the xtcp library, and I am trying to use version 4.0.1, as I am using the current versions of all other libraries and want to avoid having to include old versions of other libraries as dependencies.

There seem to be some differences between the old and new xtcp libraries. These differences are preventing the example code from working for me. In particular, the function to set up a uip server,

Code: Select all

void xtcp_server_uip(chanend mac_rx,
                chanend mac_tx,
                chanend xtcp[],
                int num_xtcp_clients,
                xtcp_ipconfig_t &?ipconfig);

which is in the file lib_xtcp/xtcp_uip/uip_server.h, has no accompanying .c file with the actual function implementation. There is an alternative implementation in lib_xtcp/xtcp_uip6/uip_server.h and lib_xtcp/xtcp_uip6/uip_server.c, but I have found that this is the exact same implementation as in the older xtcp library, and these files require an older ethernet library, where I am using the newest lib_ethernet library.

Does anyone have suggestions of what implementation of the uip server I should use and where to find it? Do I need to make other changes to the old tcp example code? Is there anything else I'm doing wrong?

Alternatively, I have tried using the lib_webserver library instead. However, if I try to include the webserver.h header file in my program, I get countless type errors in the standard library file <flash.h>:

Does anyone know what's going on in this case?

Thank you!
