In the meantime, I have solved the problem by myself.

It was related to the PINs DRAM_UDQM and DRAM_LDQM.

These pins have always been incorrectly created / designated (in version Quartus 16.1)

in a Qsys "Generate HDL ..." I changed it as follows:

# DRAM_LDQM,Unknown,PIN_V22,5,B5_N0,3.3-V LVTTL,,4ma,,,

# DRAM_UDQM,Unknown,PIN_J21,6,B6_N0,3.3-V LVTTL,,4ma,,,

DRAM_dqm[1],Unknown,PIN_V22,5,B5_N0,3.3-V LVTTL,,4ma,,,

DRAM_dqm[0],Unknown,PIN_J21,6,B6_N0,3.3-V LVTTL,,4ma,,,
