>>Can I use this cable to download!

Yes, the cable is correct.

One side is USB TYPE-C, the other side is USB TYPE-A-M.

Hi tang yuan,

pastedImage_2.png

According to schematic, your setting is no problem. But there are 2 USB Type-C connectors on i.MX8M Mini board, J301 and J302,  J302 is for power input, J301 is used for download purpose.  See test below:

1. connection

2. Connecting it to Windows USB Port

Then begin to install HID driver.

So no problem.

Have a nice day!
