I have a self-made imx8mp motherboard, the model using DDR4 is: K4ABG165WA-MCWE, the single chip capacity is 32Gb, the main frequency is 3200Mhz, my motherboard uses two chips, but the configuration cannot be completed using MX8M_Plus_DDR4_RPA_v9.xlsx

Hi @xjy198903,

Please share the schematic of the processor and DRAM interface for review.

Also, 3200 is the data rate. The cycle clock frequency will be 1600MHz.

Thanks & Regards,

According to the chip manual, I changed the configuration strategy, RSA can meet my needs:
