LPDDR4*.bin binaries for i.MX8M

Hi,

 

For i.MX8M , how the "lpddr4_pmu_train_1d_dmem.bin, lpddr4_pmu_train_1d_imem.bin, lpddr4_pmu_train_2d_dmem.bin" are generated, source code path?

For custom boards, can we use the "lpddr*.bin" binary files which are generated while building yocto for iMX8M EVK board?

We have done DDR calibration, stress test and generated code(ddr_init.c, ddrphy_train.c) and did uboot standalone compilation after adding above code to uboot. Is this fine or do we have to update "lpddr*.bin" binary files also after ddr calibration? Is there any relation among them?

 

Kindly clarify my doubts.

 

Thanks in advance.

 

Regards,

Yashavantha
