Hi nxp team
i have made a board according to imx6q-sabresd. i set switch to 01000010 to serial download mode, and succeed to download image, uboot and rootfs with mfgtools. But whatever i set switch to any boot up mode, mfgtools always show it's a HID-compliant device, and no any debug message was sent to my PC. When I use nxp release uboot-imx6q.imx,it can boot up normal.my compile uboot file can not boot,I ha change nothing about uboot ,the file between nxp release and my compile is the same size And i really don't know where is the problem. Can anyone help me?
