Re: [lwip-users] freertos + lwip = no uart ?

hmm rtos is running at higher priority than lwip so i think thats not it. but i wonder if it's relevant ? i don't use lwip right now, i just compile it into my project, but no lwip_init() is called. i dont include any .h files right now in my main.c or other project files.

task with test printf() have also blinking led and vTaskDelay() - led blinks but no message from uart.

but maybe it's just about 8kb of ram ? i didn't found anywhere about minimal requirements and after seeing project called lwip-avr (or something like that) i thought that it should run on xmega - right now i think that's what's wrong with my application.

raw lwip without os should work on my chip ?

Hi,

The code I placed was just an example.

In any case the RTOS timer interrupt should run at a higher
priority then ETH. The reason is that if you have critical
section in your code they will not be homered.

Just my two cents input...

BR,
Noam.

As far as I recall the XMega port does not support interrupt nesting, so
the parameters you highlight are not implemented for that code.
