Now, connect the i.MX8MQ Evaluation Kit to the host machine through OTG port (USB-C), your board should be detected as HID-Compliant Device.
In the folder, there are scripts to configure Mfg Tool, see image below:
As example, if you want to flash the File System (to eMMC), U-Boot and Kernel to your board, execute the script mfgtool2-yocto-mx8-evk-emmc1.vbs. In this case, the image was built with Yocto but if you want to install an Android image, run the corresponding script.
After running the desired script, a window should be displayed ready to flash the board.
