Hi igor：

      I have a DDR of the same model with different memory, now 3G and 4G can be corrected, when I press Calibration to do DDR Training  1G and 2G will have the following error, why? I use the same one DDR script (DS  file)

[igorpadykov]

you should create special DDR script (DS  file) for used memory using

MX8M_LPDDR4_RPA_v23.xlsx tool from link:

i.MX8 MSCALE SERIES DDR Tool Release (V2.10) 

then follow p.9 sect.4. Load DDR initialization script and choose correct downloading options

Hi  igor ；

When I did the stress test it showed this fail，

LPDDR4 memory (MT 53 B 512M32 D2) ；How to modify DS file？

Do you have the 2GB LPDDR4 script？

>Do you have the 2GB LPDDR4 script？

one can look at sample scripts in /script/mx8m folder of mscale_ddr_tool_v2.10

tool.
