Revision(s) Affected:

AWR1642 ES1.0 and AWR1642 ES2.0

Description:

Radar Sub System Internal Frame Clock is triggered by rlSensorStart API which starts the Radar Frame. Occasionally the rlSensorStart API does not trigger the clock due to missing synchronizer logic in hardware.

Implication: A DMA read from an unimplemented address can result in a DMA hang condition. In the resulting state the DMA will not respond to any further DMA requests.

Workaround(s):

The issue is frequent if FRC clock source is changed. Ensure that FRC Clock source is not changed.
