12.1 EDK, MPMC v6.00.a - MPMC driver hangs when using SDRAM PHY

Description

When using the MPMC calibration driver example with an SDR SDRAM PHY in EDK 11.1-12.2, the driver hangs after the StaticPhyPresent function. How do I resolve this issue?

Solution

This issue can be resolved by removing the following line from xmpmc.v, in the XMpmc_SetStaticPhyReg function:
Xil_AssertVoid(InstancePtr->ConfigPtr.StaticPhyPresent == TRUE);

This issue is fixed in EDK 12.3, in the MPMC v4_01_a driver.
