DDR calibraiton

Don´t know what it´s for. (RAM Stress test I suppose).

But after a quick glance I think it should be possible with MFGTool to get the board into OTG Mode, then send the binary for iMX6S and then execute the command.
Only thing I dont know right now is how to get the results. (Maybe copy the output into a file and then copy that onto a partition so you can read it afterwards.)

But I think it would be easier to do this in u-boot I think?

The program not only tests the DDR but is used generate all the calibrations which are used in the DCD for the DDR. The output is dumped to a serial port. The default program uses uart1. This is connected to the K20 for OpenSDA. The console here is uart2. This requires a custom program. I was looking for the version which would have been used to bring up the RiotBoard.

I´ve been looking at the documentation of i.MX6 DDR Stress Tester 1.03 right now.

There in the user guide it says to put the board into serial download mode so it is recognized as a HID Device in Windows.

And then execute the following command on the console:

DDR_Stress_Tester.exe  -t  mx6x  -df  mx6x_ddr_script_filename

Didn´t see anything that you´d need a serial port as output. As far as I can tell you can do all the calibration and stress testing right there.

Only thing I don´t see is a script for the RIoTBoard. But there is a reference script for the iMX6Solo.
Don´t know if it needs changes though.
