Imx8m mini ddr stress test

[vladimir_dolzhe]

We have custom board with samsung LPDDR4 (https://www.samsung.com/semiconductor/dram/lpddr4/K4F8E304HB-MGCJ/). I try to use mscale_ddr_tool_v310 and mx8mm_micron_lpddr4_2gb_2d_1500m_200m_50m_32bit_1cs_RPAv15.ds скрипт.

1) Result in UART in Linux:

I entered data for my LPDDR4 memory to *.xlsx and the necessary script was automatically generated. Everything works, thank you.

Maybe you can tell me how to fix the script to make it work? Connecting memory to the processor as in the reference board imx8m mini.
