stm32f7, vPortRaiseBASEPRI

Posted 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.

I'm not sure where this code comes from.

~~~~ if (inHandlerMode()) { if (xSemaphoreTakeFromISR(semaphoreid, &taskWoken) != pdTRUE) { return osErrorOS; } portENDSWITCHINGISR(taskWoken); } else if (xSemaphoreTake(semaphoreid, ticks) != pdTRUE) { return osErrorOS; } ~~~~

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?

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

There is a pre-configured STM32 Ethernet example here: http://www.freertos.org/FreeRTOS-Plus/FreeRTOSPlusTCP/TCP-IPFATExamplesSTSTM32F407.html

This is not a file that is provided in the official FreeRTOS distribution. I think it is the CMSIS wrapper provided by ST.

Thank you, I'll asked ST for more information
