i.MX8MPLUS DDR4 training files problem

[Bhardwaj]

Hi ,

1. On custom board (i.mx8mplus) we have DDR4 how can we generate ddr4_pmu_train.bin files . we also generate train bin files from firmware, we are trying to boot from fspi we are facing error as attached below.

2. USB is mandatory to get training files for DDR4 in I.MX8MPLUS from IMX DDR Tool?

3.From DDR stress test tool can we generate training files for DDR4 for custom Board.

4. Is DDR place any role For USB Detection and Data Transfer?

Hi @Bhardwaj 

We do not support customer use other ddr training file. You need to use our DDR Config Tool generated the DDR timing.c file. and use the new timing.c file compile the flash.bin file to startup the board.

2. USB is mandatory to get training files for DDR4 in I.MX8MPLUS from IMX DDR Tool?

>>>Yes, USB is necessary.

3.From DDR stress test tool can we generate training files for DDR4 for custom Board.

>>>No. only can generate the timing.c file.
