13.4 EDK, MPMC v6.03.a - MPMC GUI does not allow you to change the TWTR parameter for an LPDDR


When I select the memory type as LPDDR and select a CUSTOM in part number, MPMC GUI does not allow me to change the value for TWTR.

The parameter C_TWTR is grayed out. How do I resolve this issue?


This is a known issue and will be fixed in the future release of software. The workaround at the moment is to manually make modifications in the MHS by adding the following parameter to the MPMC below:


X will be based on the value seen in the data sheet of the LPDDR module. Make sure you are viewing the correct speed grade in the table and add the value accordingly.

This will be fixed in EDK 14.1.
