Hello Yao,
for mutexes, the RTEMS_BINARY_SEMAPHORE | RTEMS_PRIORITY |
RTEMS_INHERIT_PRIORITY are the right semaphores (please note that they
are recursive). For task/interrupt synchronization you can use
RTEMS_SIMPLE_BINARY_SEMAPHORE | RTEMS_FIFO.

hi,
I test binary semaphore used for mutex,but I find it can not block
my simple test code is
struct zynq_qspi
{
rtems_id sem_bus;
rtems_id sem_done;
bool inited;
const uint8_t *txbuf;
uint8_t *rxbuf;
int32_t bytes_to_transfer;
int32_t bytes_to_rec
