I am using a custom iMx6Ull hardware device. To flash the board we are using MFGtool in windows PC. But before the flash, (HID detection) we are facing the USB device not recognized the issue. I have checked the BOOT mode, it is as per serial downloader. And also check continuity for boot mode and USB interface. I have also installed the USB driver but no luck.
Kindly provide the solution.
