[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [August 2016 Threads] stm32f7, vPortRaiseBASEPRIPosted by bsoti on August 29, 2016 Hello, I want to start ethernet on stm32f7 but task always sticks on one place -
if (inHandlerMode())
{
if (xSemaphoreTakeFromISR(semaphoreid, &taskWoken) != pdTRUE) {
return osErrorOS;
}
portENDSWITCHINGISR(taskWoken);
}
else if (xSemaphoreTake(semaphoreid, ticks) != pdTRUE) {
return osErrorOS;
}
, and when I put breakpoint I receive this message:
Program received signal SIGINT, Interrupt.
0x08005352 in vPortRaiseBASEPRI () at C:/Projects/STM32F7/Middlewares/FreeRTOS/Source/Portable/GCC/ARM_CM7/r0p1/portmacro.h:215
215 __asm volatile
Any idea why is that. When I put my code in exmple of ethernet at stm it works fine.
stm32f7, vPortRaiseBASEPRIPosted by heinbali01 on August 29, 2016 I'm not sure where this code comes from.

It looks like inHandlerMode() returns true if the function is called from an ISR?
Where did you get your NetworkInterface.c from? Does that contain the above code?
stm32f7, vPortRaiseBASEPRIPosted by bsoti on August 29, 2016 NetworkInterface.c I didnt have this file.
~~~
int32t osSemaphoreWait (osSemaphoreId semaphoreid, uint32t millisec)
{
TickTypet ticks;
portBASE_TYPE taskWoken = pdFALSE;
if (semaphore_id == NULL) {
return osErrorParameter;
}
ticks = 0;
if (millisec == osWaitForever) {
ticks = portMAXDELAY;
}
else if (millisec != 0) {
ticks = millisec / portTICKPERIOD_MS;
if (ticks == 0) {
ticks = 1;
}
}
if (inHandlerMode()) {
if (xSemaphoreTakeFromISR(semaphoreid, &taskWoken) != pdTRUE) {
return osErrorOS;
}
portENDSWITCHINGISR(taskWoken);
}
else if (xSemaphoreTake(semaphoreid, ticks) != pdTRUE) {
return osErrorOS;
}
return osOK;
}

This is whole function. It is in cmsis_os.c
stm32f7, vPortRaiseBASEPRIPosted by rtel on August 29, 2016 There is a pre-configured STM32 Ethernet example here:

This is not a file that is provided in the official FreeRTOS
distribution. I think it is the CMSIS wrapper provided by ST.
stm32f7, vPortRaiseBASEPRIPosted by bsoti on August 29, 2016 Thank you, I'll asked ST for more information
