Ah, I manually tried this change below: --- a/configs/mx6sabresd_defconfig +++ b/configs/mx6sabresd_defconfig @@ -40,6 +40,8 @@ CONFIG_SPL_WATCHDOG=y CONFIG_HUSH_PARSER=y CONFIG_SYS_MAXARGS=32 CONFIG_CMD_BOOTZ=y +# CONFIG_BOOTM_PLAN9 is not set +# CONFIG_BOOTM_RTEMS is not set CONFIG_CMD_SPL=y CONFIG_CMD_SPL_WRITE_SIZE=0x20000 CONFIG_CMD_GPIO=y @@ -65,7 +67,7 @@ CONFIG_EFI_PARTITION=y # CONFIG_SPL_EFI_PARTITION is not set CONFIG_OF_CONTROL=y CONFIG_OF_LIST="imx6q-sabresd imx6qp-sabresd imx6dl-sabresd" -CONFIG_MULTI_DTB_FIT=y +CONFIG_MULTI_DTB_FIT_LZO=y CONFIG_ENV_OVERWRITE=y CONFIG_ENV_IS_IN_MMC=y CONFIG_SYS_RELOC_GD_ENV_ADDR=y After running make savedefconfig; cp defconfig configs/mx6sabresd_defconfig, I see that CONFIG_MULTI_DTB_FIT_LZO does not get selected, and CONFIG_MULTI_DTB_FIT=y is removed. According to doc/README.multi-dtb-fit: "Usually the DTB is selected by the SPL and passed down to U-Boot. But some platforms don't use the SPL. In this case MULTI_DTB_FIT can used to provide U-Boot with a choice of DTBs" mx6sabresd uses SPL, so MULTI_DTB_FIT can be safely dropped. I tested it on a imx6dl and imx6q sabresd boards. I'll send a v2. Thanks
