6.2 EDK - The FIT timer does not generate an Interrupt output

Description

Keywords: XPS

Urgency: Standard

General Description:
The FIT_timer Core is a peripheral that generates a strobe signal at fixed intervals and is not attached to any bus. The Core tries to implement the counter in the most efficient way using SRL16, but for certain values of C_NO_CLOCKS, the Core cannot implement the timer using the SRL16. In this case, a normal bit counter is implemented. In order to use SRL16, the value of C_NO_CLOCKS must be factorized into values between 2 and 16.

If a counter is chosen, the FIT_timer peripheral will not generate an Interrupt strobe.

Solution

This problem is fixed in the latest 6.3 EDK Service Pack, available at:

The first service pack containing the fix is EDK 6.3 Service Pack 1.
