Hello XianYo,

Can you please tell me which evaluation board are you using?... did you download both the bsp and mfg tools?.

Can you be more specific on what you can't do?

You can ask a software engineer to help you review the uboot source code by searching "is_boot_from_usb".

From the 3.10 BSP, the uboot is shared with mfg tool. 

uboot-imx\common\main

#ifdef is_boot_from_usb

if (is_boot_from_usb()) {

  printf("Boot from USB for mfgtools\n");

  bootdelay = 0;

  set_default_env("Use default environment for mfgtools\n");

} else {

  printf("Normal Boot\n");

}

#endif
