Bug in STM32Cube FreeRTOS wrapper (with fix)

Posted on July 23, 2015 at 12:19

Hello.

There is a bug in the cmsis_os.c file:

at line 757:

  return xQueueCreate(queue_def->queue_sz, (uint32_t) sizeof(queue_def->item_sz));

sizeof(item_sz) is always 4, so all queues are created with element size = 4, not item_sz.

It should be

  return xQueueCreate(queue_def->queue_sz, (uint32_t) queue_def->item_sz);

instead.

Also, there is another misuse of size_of in the same file at line 936.

Looks like there is already topic about it:
