Xilkernel: Each message queue requires two semaphores

Jump to solution

Each xilkernel message queue requires two semaphores.

 

Thus, simply setting num_msgqs in the BSP configuration to your desired number of queues is not sufficient. This may result in ENOSPC errors, even though you thought you allocated the correct number of queues. To fix this error, make sure that max_sem is set to at least 2 * num_msgqs.
