HI ALL

I am study the ddr4 calibrate steps now, and have some confuse for ddr4 calibrate with following link.

https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-8M-Family-DDR-Tool-Release/ta-p/110...

From the MSCALE_DDR_Tool_User_Guide.pdf,  it seems that the target platform didn't need run any sd card image when ddr4 calibrate, why MSCALE_DDR_Tool.exe can download the bin file to the target?

regards

jason
