Weird problem RTOS or compiler related void app_SendBuffer (void *argument) {
uint32_t dma_index;
char Message1[26];
bool a;
sprintf (Message1, "BufferSize_inBytes = %u\n", AdcHalfBufferSize_inByte);
osDelay(5000);
while (!USBD_Configured(0)) {
osThreadYield ();
}
USBD_CDC_ACM_WriteData(0U,(uint8_t*)Message1,sizeof(Message1));
ADC_DMA_Start();
for (;;){
osThreadFlagsWait(0x00000020U,osFlagsWaitAll,osWaitForever);
dma_index = osThreadFlagsWait(0x00000006U,osFlagsWaitAny,osWaitForever);
a=dma_index&2;
GPIO_PinWrite (GPIOC,14,a);
sprintf (Message1, "Index = %u", a);
USBD_CDC_ACM_WriteData(0U,(uint8_t*)Message1,9);
}
}Here is my example code , i can get "a" value as 1,0,1,0,1,0 .Code works as i expected.But if i try to write directly index as like this ;I always read 2,2,2, then always 5 dma_index = (osThreadFlagsWait(0x00000006U,osFlagsWaitAny,osWaitForever) );
a=dma_index&2;
GPIO_PinWrite (GPIOC,14,a);
sprintf (Message1, "Index = %u", dma_index);
USBD_CDC_ACM_WriteData(0U,(uin
