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?
Doesn't it depend on which generation of MScale one is using?
Anyway, from NXP's user guide [1]:
For i.MX 8M Quad and i.MX 8M Mini LPDDR4 EVK, copy lpddr4_pmu_train_1d_dmem.bin,
lpddr4_pmu_train_1d_imem.bin, lpddr4_pmu_train_2d_dmem.bin, and
lpddr4_pmu_train_2d_imem.bin from
firmware/ddr/synopsys of firmware-imx package to imx-mkimage/iMX8M/.
For i.MX 8M Mini DDR4 EVK, copy ddr4_imem_1d.bin, ddr4_dmem_1d.bin,
ddr4_imem_2d.bin, and ddr4_dmem_2d.bin
from firmware/ddr/synopsys of firmware-imx package to imx-mkimage/iMX8M.
For i.MX 8M Plus LPDDR4 EVK, copy lpddr4_pmu_train_1d_dmem_201904.bin,
lpddr4_pmu_train_1d_imem_201904.bin,
lpddr4_pmu_train_2d_dmem_201904.bin, and lpddr4_pmu_train_2d_imem_201904.bin
from firmware/ddr/synopsys of
firmware-imx package to imx-mkimage/iMX8M/.
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.
Okay, I guess NXP uses it for their proprietary imx-mkimage stuff for the i.MX
8M Plus:

But, as mentioned above, I could not find any official documentation not to
mention release notes about any of
this anywhere.
@NXP: Anybody mind telling us more about this?
Please use the one mentioned in imx-mkimage matching the release tag.
The documentation was missed to be updated, thanks for pointing this out.
Thanks,
Peng.
So their latest documentation does not even mention the later firmware
available!
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
