freertos and socket [message #1829836]

stuggling on stm32 is really difficult.
the document of freertos+lwip is just half of the work.
another half is about the PHY+MAC configuration
As i compared win32 and freertoslwip, that i find the socket setting is in bsdsocketinterf.cpp,
but i add breakpoint at openTCPServerConnection function, and when it's running,
it didn't stop at the breakpoint.
Is bsdsocketinterf.cpp used as the socket initial ?
are there any example for stm32 for forte?

it seems that under win32 :
DWORD WINAPI CWin32Thread::threadFunction(LPVOID arguments){
CThreadBase::runThread(static_cast<CWin32Thread *>(arguments));
return 0;
}
can run into threadbase.tpp

but under stm32,
void CFreeRTOSThread::threadFunction(void *paData){
CThreadBase::runThread(static_cast<CFreeRTOSThread *>(paData));
/* Tasks must not attempt to return from their implementing
function or otherwise exit.
https://www.freertos.org/implementing-a-FreeRTOS-task.html */
vTaskDelete(NULL);
}
can't run into threadbase.tpp
just hanging up at CThreadBase::runThread(static_cast<CFreeRTOSThread *>(paData));

The documentation is to run forte on a stm32 board where the networking is already set. PHY+MAC configuration is a general configuration and not one specfic to forte.

Have you enabled:

#define configCHECK_FOR_STACK_OVERFLOW 1
#define configUSE_MALLOC_FAILED_HOOK 1

and the corresponding functions?

i have already enabled these follow the document, there are no errors about memory now,
the problem is
void CFreeRTOSThread::threadFunction(void *paData)
is hanging up
can't step into the bsdsocketinterf.cpp

i use W5500 as the ethernet hardware, the W5500 implements the socket, so does it mean we don't have to use the lwip?

From a quick look at the web-page of this chip I would say you need to use their special IO library. however i haven't looked into their lib and also don't know how to integrate it into 4diac FORTE.
