I was having the same problem and I found that was related to diff --git a/arch/arm/mach-imx/imx8m/soc.c b/arch/arm/mach-imx/imx8m/soc.c index 863508776d..9d6dab08e6 100644 --- a/arch/arm/mach-imx/imx8m/soc.c +++ b/arch/arm/mach-imx/imx8m/soc.c @@ -1333,6 +1333,7 @@ enum env_location env_get_location(enum env_operation op, int prio) You should support USB_BOOT in switch case or change your defconfig and add CONFIG_ENV_IS_NOWHERE=y Michael > > Best regards, > > Tim
