Ok, I didn't even notice that and I just wanted to make sure I was using the right ones here. Maybe someone can tell us the use case for the "*_202006.bin" files.

i.MX LPDDR4 Firmware
Hi all, I see that in the NXP firmware-imx package different versions of the LPDDR4 train firmware is included but I cannot find a Release Note or something else that describes the differences. Does anyone know what is the correct version to be used? Here is the content of the latest NXP release: lpddr4_pmu_train_1d_dmem_201904.bin lpddr4_pmu_train_1d_dmem_202006.bin lpddr4_pmu_train_1d_dmem.bin lpddr4_pmu_train_1d_imem_201904.bin lpddr4_pmu_train_1d_imem_202006.bin lpddr4_pmu_train_1d_imem.bin lpddr4_pmu_train_2d_dmem_201904.bin lpddr4_pmu_train_2d_dmem_202006.bin lpddr4_pmu_train_2d_dmem.bin lpddr4_pmu_train_2d_imem_201904.bin lpddr4_pmu_train_2d_imem_202006.bin lpddr4_pmu_train_2d_imem.bin Thanks -- Heiko
