What is the platform_build version which you have patched? 2. When you say: add the related flags in device config, you mean to $ ./build.sh BUILD_TARGET_FS=ubifs The BUILD_TARGET_FS variable works with the imx6_target_fs.mk file ------imx6_target_fs.mk------ ifeq ($(BUILD_TARGET_FS),ubifs) # build ubifs for nand devices TARGET_USERIMAGES_USE_UBIFS := true TARGET_USERIMAGES_USE_EXT4 := false PRODUCT_COPY_FILES += \ device/fsl/imx6/etc/fstab_nand.freescale:root/fstab.freescale else # build for ext4 TARGET_USERIMAGES_USE_EXT4 := true TARGET_USERIMAGES_USE_UBIFS := false PRODUCT_COPY_FILES += \ device/fsl/imx6/etc/fstab.freescale:root/fstab.freescale endif # BUILD_TARGET_FS ----------------------------------------- I have out/host/linux-x86/bin/mkfs.ubifs. Thanks in advance.
