IMX8MM 16 bit DDR4 training scripts

We build a custom board, where the PCIe and VPU IP cores are unconnected and unpowered.

The SAI1 is powered but all the IOs are unconnected.

The DDR memory is routed with the 16-bit data bus only.


Apparently, we found that the actual DDR training software provides no scripts for the 16-bit DDR4 memory.

The existing scripts/firmware hangs immediately after upload.


Any chance it is an easy-to-solve issue?
