We have designed a board with iMx6Q processor. We are doing bringup of that board. voltages, clock etc is tested OK. Using DDR Stress tool, we have verified the memory in the board too. Now we were trying to use iMX USB Loader and boot the board from memory. We installed iMX USB loader in a Ubuntu machine. powered up the board, put the boot mode as serial download and connected USB OTG port to Ubuntu machine. But when we try to load Uboot image, we were getting error that it is not able to open the device. The log message is given below for information. Can anyone help in identify the issue?
