[U-Boot] saveenv not working with CONFIG_ENV_IS_IN_UBI

[U-Boot] saveenv not working with CONFIG_ENV_IS_IN_UBI

[Richard Cagley]

I am unable to have my uboot environment variable persist when using saveenv.

I have these configs set
#define MTDIDS_DEFAULT "nand0=xilinx_nand"
#define MTDPARTS_DEFAULT \
        "mtdparts=xilinx_nand:" \
                "8M(boot)ro," \
                "16M(env-boot)," \
                "20M(itb)," \
                "-(root)"
#define CONFIG_ENV_IS_IN_UBI
#define CONFIG_ENV_UBI_PART "env-boot"
#define CONFIG_ENV_UBI_VOLUME "u-boot-env1"
#define CONFIG_ENV_UBI_VOLUME_REDUND "u-boot-env2"

Once in u-boot I do something along these lines:
mtdparts default
nand erase.part env-boot
ubi part env-boot
ubi create u-boot-env1 0x20000 dynamic
ubi create u-boot-env2 0x20000 dynamic
setenv foo 1
saveenv
saveenv
reset
printenv foo
## Error: "foo" not defined

thanks

Can you provide some more informations?

On which hw?

Is the board support for your hw in mainline?

Does UBI support work at all on your hw?

Please provide a full log, may with ubi debug enabled.

Thanks!

bye,
Heiko
