second time uboot-usb.imx file is not loaded using mfgtool, it is getting stuck at loading file. find the log below. how to recover my board to reflash?

Not using the newer BSP and IMX6G is used

Which version of bsp are you using? For the board are you using the NXP reference board or the board you designed yourself?

Which board and bsp are you using? If you are using the newer BSP, you can use the uuu tool we supply.
