Hi Aditya,
What board are you using?
Please note that MFGtool was developed to be used with our evaluation boards. If you want to use MFGtool with a custom board you need to build an image that Yocto provides with all the settings to be used with MFGtool and edit it with you ddr settings.
Please find below some discussions and documents about this:
MFGTool for custom i.MX6SL board
Custom board MFG tool support
i.MX6 DDR Stress Test Tool V1.0.3
i.MX6DQSDL DDR3 Script Aid
Best regards,
Carlos
