There are ATMEL Studio 6.2 , core FRTOS 8.2.3, board based on ATSAM3S4A (not dev board) . I create new project , then added frm ASF Wizard freertos-spi(UART,TWI) interface layer(service) , replace a core 7.3.0 (wich added automatically ) with FRTOS 8.2.3, and for the first i make up only 1 task wich using uxTaskGetNumberOfTasks, vTaskList and output info to UART0, it's work fine, then i add SPI func. - freertosspiwritepacket ,it became crashing in xQueueGiveFromISR func. configASSERT( !( ( pxQueue->uxQueueType == queueQUEUEIS_MUTEX ) && ( pxQueue->pxMutexHolder != NULL ) ) );

ATSAM3S4A FRTScore 8.2.3 + freertos-spi interface layer(service) (AtmelStudio 6.2)Posted by rtel on December 6, 2015 This is due to a change in the way mutexes can be used. Try updating the ASF code so it creates a binary semaphore (xSemaphoreCreateBinary()) instead of a mutex (xSemaphoreCreateMutex()).

The same project with FREERTOS 7.3.0 Library Work fine - return Status_OK(0)
ATSAM3S4A FRTScore 8.2.3 + freertos-spi interface layer(service) (AtmelStudio 6.2)Posted by rtel on December 7, 2015 If the 7.3.0 code works with the binary semaphore, but the 8.2.3 doesn't
then I will need to dig a little deeper...
