Can we do DDR4 calibration IMX8MP custom board, without USB OTG?

[abhiroopnray]

We have made a custom board from IMX8MP. 

In the board there is no USB OTG available. 

USB hosts are available though.

Is there any way to do DDR calibration using MScale DDR  Tool, without USB OTG?

Hello @AldoG 

Thank you for the response.

I would like to know, if there is any way we can connect the board with Linux OS?
I can see MScale DDR  Tool is only available in .exe format. Is there any variant for Linux OS?

Hi,

You may try using the config tool for i.MX, available for download here:

This tool support DDR stress test for i.MX8M family devices.

Best regards,
Aldo.

Hello,

No, it is not possible as specified in the DDR stress tool user guide:

It is a program running on the PC side which downloads a test image to the i.MX series processor’s internal RAM through a USB connection.

Best regards,
Aldo.

Does it also work with a simple USB device interface?
