2014.3 SDK - LibXil SKey v2.0 - The library could not program or not read the PL eFUSE


This issue only affects the PL eFUSE. 

The issues cause the library to not program or not read the PL eFUSE. 

eFUSE programming or read request data will not get to the PL TAP.

If affected, it will be a time zero failure.

The PL eFUSE will not be accidentally programmed incorrectly, instead it will just not get programmed at all.


There is a less than 1 in 8 chance that your code is built in a way that will trigger the issue.

The issue was that an arbitrary value was being pulled from a null (address zero) pointer instead of a valid BYPASS instruction for the PS DAP. 

There are 16 possible opcode values for the PS TAP and only 2 of the 16 can cause an issue

To fix the issue apply the attached patch.

This issue is targeted to be fixed in the 2015.1 release.
