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

[Grzegorz Niemirowski]

Damian, could you provide a piece of code you use for accessing UART? Do you use functions named like send()? Maybe you have LWIP_COMPAT_SOCKETS defined and functions redefined?

#define send(a,b,c,d)         lwip_send(a,b,c,d)

Best regards,

Grzegorz Niemirowski

hi, hmm i don't see any messages about memory exceeding the resources available or  something like "memory could not be "Written"" - but i never looked at map file so i could be wrong (following this http://www.codeproject.com/Articles/3472/Finding-crash-information-using-the-MAP-file) - what should i be searching for ?

nothing seems wrong for my level of knowledge.

for me it's wierd that only uart is not working, freertos tasks are fine, application is working - the only thing is that i don't get messages to my terminal.

maybe i should buy external crystal ? i'am working on 32Mhz internal xmega clock right now.

Hi,

Have you had a look at the linker map file? My guess is that the additional memory requirements has exceeded the resources available.

Cheers,

Adam.

hi, i'am trying to port FreeRTOS + lwip to atxmega128a3u and almost every
thing is working fine, only my uart wont fire up when i compile my project
with lwip files included, what can be the cause of this ? Any help would be
appreciated.

without lwip files uart is working great
with lwip files i just get one character "?" upon uart init function and
nothing else, tasks are still working fine.

tried uart with and without interrupts

lwip is not initialized in my project, only compiled

i'am using
microchip: atxmega128a3u on internal 32mhz clock
freeRTOS 8.2
lwip 1.4.1

any help where should i search for erros ? right now i can't use my debugger
becouse there is something wrong with amtel-ice+osx+avrdude so i'am stuck...
