Yes, as I posted in another thread, the MTD, UBI are all set in my Linux kernel defconfig, I have also added UBOOT_CONFIG = "nand" in my layer machine config. What I missed is u-boot overlay, as you and Andy alluded. I added UBOOT_CONFIG[nand] += "mx6ull_14x14_evk_nand_config", but strange enough, that mx6ull_14x14_evk_nand_config, did not set CONFIG_CMD_UBI in its config. I think I need to add an appended recipes-bsp to my layer just like I added the recipes-kernel to my layer to overwrite kernel defconfig, I need to overwrite u-boot defconfig. In kernel, to overwrite defconfig, I run bitbake -c menuconfig virtual/kernel, how can I generate u-boot defconfig, to run bitbake -c menuconfig u-boot? Thank you. Kind regards, - jh
