Hi,
I am trying to run a simple application on TI814x device and run into this issue. Whenever time dependent OS calls were made, the control would never return.
The same application works fine on TI816x device.
I think i am missing something very basic, just unable to figure out. Could you please help me out. Below is the configuration file that i am using.
Thanks,Sujtih
