Hi everybody,
I'm using omapl138 and I'm struggling with the following issue while developnig a DSP application.
I'd like to have 2 syslink objects : ringIO and messageQ and ADC/DAC processing at the same time. From the syslink examples I'm able to create DSP application which uses only syslink objects - no issues here and that works fine. Then I'd like to add ADC data processing, so I have HWI+SWI handlers to do this. But with this I'm not able to link to DSP from ARM side ( I'm using ARM-side application from the examples to do this ).
My system looks as follows :
1. HWI thread
2. SWI thread
3. MessageQ task
4. RingIO task
I create these objects dynamically via Task/Swi/Hwi_create() api. Inside the ISR handler of HWI I call Hwi_disable for the first time to let the tasks run - but no success, my ARM-side application is not able to sync with DSP.
If I comment out HWI thread, my ARM-side application works fine. So the problem deals with HWI interrupts and syslink tasks...
Can anybody help me ? What is the right way to have HWI + syslink in one system ?
Is there any way to stop HWI, let the tasks run for a while to sync with ARM and then let the HWI run further?
BR,
Dmitry
