FPGA send doorbell to C6678 through SRIO per 0.5 seconed, after reveiving the doorbell, the doorbellISR post once semaphore, then the task1 pend the semaphore, and nwrite counter to FPGA. This is one cycle. But sometimes the test failed with error info:
ti.sysbios.knl.Semaphore: line 214: assertion failure: A_pendTaskDisabled: Cannot call Semaphore_pend() while the Task or Swi scheduler is disabled.
xdc.runtime.Error.raise: terminating execution
is the gap too short ?
