It sounds like that bootloader doesn't came up. You will need to add / replace the following files in the FAT partition of an raspbian: kernel.img (U-Boot) boot.scr.uimg bcm2835-rpi*.dtb (from kernel) zImage > > ...another interesting idea would be to try to see if you could just > change the configuration of the Raspberry Pi kernel to switch which > dwc2 driver it used.
