vTaskNotifyGiveFromISR not waking up the taskPosted by cjedic on June 2, 2016 I am calling "ulTaskNotifyTake( pdTRUE, portMAX_DELAY )" from a function called by a task. I get to the interrupt routine consistantly and I do a "vTaskNotifyGiveFromISR( xdmacChannelNotification[i], NULL );" but the isr never finishes and never gets back to the function where it did the take. Is there anything I can check for configuration? Any clues? vTaskNotifyGiveFromISR not waking up the taskPosted by rtel on June 2, 2016 Is xdmacChannelNotification[i] a valid task handle? Step into the vTaskNotifyGiveFromISR() function in the debugger to see what it does, and where it goes. Regards. vTaskNotifyGiveFromISR not waking up the taskPosted by cjedic on June 2, 2016 it has asserted at this line in vPortValidateInterruptPriority() configASSERT( ucCurrentPriority >= ucMaxSysCallPriority ); vTaskNotifyGiveFromISR not waking up the taskPosted by edwards3 on June 2, 2016 The interrupt priority is not valid, see http://www.freertos.org/RTOS-Cortex-M3-M4.html vTaskNotifyGiveFromISR not waking up the taskPosted by cjedic on June 2, 2016 Turns out I had the priority of the interrupt too high. lowering made it work.
