MX8MM won't enter fastboot mode

Hello, I'm using MX8M Mini EVK with Android 9, under Windows 10. *ADB works* fine but I have a real trouble getting into fastboot mode.  I researched hard in all NXP documents - "Android_User's_Guide.pdf", "Android_Quick_Start_Guide.pdf" and even followed iMX6 instructions on how to config fastboot. Nothing works though. 


1. Obviously, both "developer mode" as well as "OEM unlocked" option are enabled.

2. When I run "adb shell reboot bootloader" the board is being rebooted but all I see is a blanked screen and both "fastboot oem unlocked" nor "fastboot usb" command ever returns.

3. I have the latest Google USB driver installed (tried to add vendor ID from iMX6 documentations, didn't really work either)

4. It should be noted that I was able to flush the images through UUU (with a new NXP build android_p9.0.0_2.0.0-ga_image_8mmevk.tar.gz)  but even with this new build the board won't enter fastboot mode.


Is there any change that needs to take place in the "android_winusb.inf" or "adb_usb.ini" ?


One last note, once the EVK board is booted in attempt to get into fastboot, instead of seeing "EVK_8MM" the device is changed to "USB download gadget", no idea if that's normal?


I will appreciate any help!


Thanks, Mike
