Good Morning,
Has anyone run into any problems with using the RTX isr_mbx_send() call? Specifically, if a back to back use of this call is done within an ISR I am seeing that the first task mailbox entry posted is (periodically) overwritten by the second. The only tasks running during this occurance are the receiving mail task and another lower priority task. The UART driver interrupt where this test is being initiated is also the highest priority interrupt in the system. The documentation does not suggest any usage limitations with this call. Thanks.
