Which parameters are shared by kernel and u-boot?

Hi, Does kernel and u-boot both need be compiled by u-boot configure files to include bootargs, mtdpars etc? Thank you. Kind regards, - jh

u-boot saveenv corrupted other MTD parttions

at 0x5e -- 100% complete. Writing to NAND... OK It looks like that saveenv overwritten to the storage, is 0x5e RAM or NAND address? Where was that address defined? How do I know it was the NAND 1m(ubootenv) address? Thank you. Kind regards, - jh

[U-Boot] What is the current U-Boot status to boot from multiple UBI volumes?

Support UBI u-boot

to do it? If not, what is the policy for making parches and commit to the git repository https://source.codeaurora.org/external/imx/uboot-imx.git? Thank you. Kind regards, - jh

Re: [yocto] Support UBI u-boot

xternal/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

Re: [yocto] Support UBI u-boot

, 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

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. Kind regards, - jh On 2/9/20, JH wrote: > Changed to https://source.codeaurora.org/

[U-Boot] Set up NAND UBIFS partitions

partition every time in rootfs partition boot that is definitely a wrong way. What is a proper way to fix it? Thank you. Kind regards, - jh ___ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
