In data sheet, DRAM_AC04 <-> CK_t_A and DRAM_AC24 <-> CK_t_B, but in the reference design, DRAM_AC04 <-> CK_t_B and DRAM_AC24 <-> CK_t_A?
In the i.MX8MMini EVK design, the LPDDR4 channels _A and _B are completely swapped with regard to the LPDDR4 chip. This is done for the PCB routing convenience.
I am not really sure, but I´ve noticed:
If you do not connect the pins as in the reference design, there will be crossings at the end, in the routing.
So i think it´s just because it´s better for the layout.
