There was for a long time a mix between Kconfig options and options in what I call board header files (include/configs/.h). Most likely CONFIG_MTD_PARTITIONS had to be defined there.

Re: [yocto] Support UBI u-boot
Anyway, hacked the Makefile and mtdpart.c, finally got it compiled to support UBI. I think some latest branch might fix the problems I haven't tested, if not, I am happy to make patches. Thank you all.

Re: [yocto] Support UBI u-boot
Changed to https://source.codeaurora.org/external/imx/uboot-imx.git branch imx_v2018.03_4.14.98_2.0.0_ga, it can now support CONFIG_CMD_MTDPARTS ind defconfg, all MTDPARTS error gone, but then 2018.03-r0/git/cmd/ubi.c missed dependencies of del_mtd_partitions, add_mtd_partitions, mtd_get_device_size all in mtdpart.c which can only be enabled by CONFIG_MTD_PARTITIONS: obj-$(CONFIG_MTD_PARTITIONS) += mtdpart.o But that CONFIG_MTD_PARTITIONS is not supported in defconfig. Could anyone advise which branch works for UBI? Thank you. Kind regards, - jh

Hi Gabriele, Thanks for the help.

It does not seem the OE / Yocto build issue, rather than the u-boot build issue. I can build OE / Yocto to load my mx6ull_14x14_evk_nand_defconfig to replace the original source git/configs/mx6ull_14x14_evk_nand_defconfig. The git/scripts/kconfig was able to run defconfig mode that git/scripts/kconfig/conf.c and git/scripts/kconfig/confdata.c was able to enable CONFIG_CMD_UBI and to write to the .config based on my mx6ull_14x14_evk_nand_defconfig, but git/scripts/kconfig/conf.c and git/scripts/kconfig/confdata.c were not able to generate CONFIG_CMD_MTDPARTS (I could not find CONFIG_CMD_MTDPARTS when I made menuconig from menu config either). The git/cmd/Makefile requires CONFIG_CMD_MTDPARTS set up to run mtdparts.c, without CONFIG_CMD_MTDPARTS, mtdparts.c was not compiled, and other cmd source files were not compiled, thus missing all dependencies for ubi (undefined reference). Is it buggy in u-boot source downloaded from https://source.codeaurora.org/external/imx/uboot-imx.git (commit "8be98e9322040c655b9e5c9fb2c494e002e3fad9"), or is just my silly stupidity to miss things? Could anyone in u-boot source development help to comment our if https://source.codeaurora.org/external/imx/uboot-imx.git (commit "8be98e9322040c655b9e5c9fb2c494e002e3fad9") works for ubi or not? Or what I could be missing? Apologize to cc source contributors. Thank you. Kind regards, - jh

Simply source /opt/poky/.../env-script make -j4 If you just want to run the menuconfig run make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig and make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- savedefconfig In any environment. > Thank you Gabriele for great helps. > > Kind regards, > > - jh > Gabriele

It seems that build environment will not be the same as the Yocto build environment I am currently running on Ubuntu 18 host. Thank you Gabriele for great helps. Kind regards, - jh

I usually have a local clone of uboot and I simply run `make [...] menuconfig|savedefconfig` , then I create a patch to add my defconfig (custom_defconfig) to configs/ and specify UBOOT_MACHINE = "custom_defconfig" Thank you. > > Kind regards, > > - jh > Gabriele

Hmm, more complicated than I thought, it does not have defconfig in u-boot like kernel does, how do you overwrite u-boot config in Yocto?

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
Re: [yocto] Support UBI u-boot
Hi JH, have you tried what we suggested you in your last thread? More specifically adding your defconfig and tweaking it through menuconfig. and then specify the UBOOT_MACHINE. However you should be able to create and apply patches for external repo without any problem and the needs to push your changes to public repos (unless them are useful for others).
