here is a powerpc MPC83xx platform, many years ago from express logic.external interrupt generate per 100us,.

tx_event_flags_get（...., wait_option）, if wait_option=waitforever everything is ok, if wait_option = number such as 500, then cannot catch external interrupt.
any suggestion to debug this?
and either a update port for powerpc?

    Seems the latest threadx release use a basepri which can let external interrupt arrive processor directly, it maybe can fix my problem,
    Does there a port demo?
