RE : [lwip-users] Adding more applications and protocols

[Frédéric BERNON]

Hi,

 

I don't know your port, but there is two possibilities :

 

- your sys_arch_timeouts is able to create directly the timeouts list for the calling thread: in this case, you can use any function to create your thread.

 

- your sys_arch_timeouts can't do it, and will returns NULL for a thread which is not create by sys_new_thread: you can create your thread will any function IF you don't use directly or indirectly any sys_timeout()/sys_untimeout() calls in this thread context. Indirect calls can be sys_mssleep() & lwip_select()/select(), In others cases, or if you're not sure, you HAVE to use sys_new_thread.

 

 

If you have to implement your own sys_arch, perhaps a simple table (static or dynamic) indexed by any threadID is a good solution to implement sys_arch_timeouts(). In some OS, but I don't know FreeRTOS, it's possible to have a "Thread Local Storage". If you get a such possibility, you can use it.

Objet : [lwip-users] Adding more applications and protocols

 

I have the HTTP web server working well under Freertos and the SAM7X.

My question; what is the correct way to add additional protocols (UDP) and apps (TFTP), and additional HTTP connections

Should I create additional tasks using the FREERTOS calls for “xTaskCreate”,

or create them using the “sys_thread_new” functions within sys_arch. This will add an entry to the timeout table.

 

A point in the right direction will help

Thanks

 

Colin
