We have 4 Nexys 4 DDR boards with the same "Rev C" revision.
I have compiled .bit file with MIG IP settings based on Digilent example "Nexys 4 DDR Xilinx MIG Project" in Vivado 2018.1
The fist two boards have MIRA DDR2 chip and DDR calibration complete successfully with this .bit file
The second two boards has ISSI DDR2 chip and DDR calibration fails with the same .bit file.
What are the MIG setting differences for these DDR2 chips?
