Iam using Zynq702, in this we have an hardware that can communicate with the Processing System (PS) using AXI bus.PS is AXI Master.
Data Flow and Hardware Details as mentioned below:
Data From Wire–> Programmable Logic (FPGA) – > BRAM --> AXI Interconnect --> PS
After the above sequence the data is made available to the PS(ARM Core).
Interrupt is sent to PS to start fetching using SCUGuic using GPIO from PL to PS.
In FreeRTOS (8.2.3) created 1 interrupt and 1 task.
Priority of this interrupt task is greater than RTOS timer interrupt.
In this Interrupt routing FromISR function only used to notify the Task.
Below are the obervation.
1.Works fine for 98 times, interrupt able to notify the task
2.On 98th time interrupt occurs and NotifyFromIsr also called but the break point is not hitting the task.
As a RTOS it should not fail to start any task from the interrupt.
I don’t know why it failing in the FreeRTOS.
Tried to debugging using StateViewer but not able to see for FreeRTOS.
Is there any way to fix this issue.
