DDR3 setup

Hello, I can't configure the HPS DDR3 memory on a custom board with the Cyclone V SoC. The memory is IS43TR16512A-125KBLI. The preloader stops in the rw_mgr_mem_calibrate_read_test_patterns function...

Hi KKomp,

It's good that you found the root cause on the board but unfortunately HPS DDR3 IP comes with dedicated fixed pin connection. Therefore, you can't swap the RAS and CAS pin.

You can try rework your board as you mentioned or do a proper design respin on your board.
