IMX8M Nano DDR4 Stress tool error

Hi,

When running the DDR calibration we get the following error over and over again:

============ Step 3: DDR parameters processing... ============
;�&
ERROR: STATUS_MSCALEPHY_RESULT failed in UART communication
Please restart this tool and try again!

We use the following configuration:

- MSCALE rev 3.0

- Configuration spreadsheet for Nano rev. 4.0

- 1GB Samsung K4A8G165WC (2666)

- CPU - PIMX8MN6DVTJZAA

What is the meaning of that message?

Are you launch the MSCALE_DDR_Tool.exe in administrator mode?

Yes,

It turn out to be a UART's signal integrity problem

Thanks
