undefined reference to `fw_env_open'

[luigi onida]

Hello Stefano,

my actual configuration of yocto conf is:

PREFERRED_PROVIDER_u-boot-fw-utils = "u-boot-imx-fw-utils"

using this patch:

https://community.nxp.com/t5/i-MX-Processors/compile-error-u-boot-fw-utils-under-yocto-zeus/m-p/1070895

Why I cannot have reference to  fw_env_open, fw_env_close, fw_env_write .. ?

Thank you

[Stefano Babic]

Why are you surprised ?

You are using a special vendor version, too. You have to ask NXP for it.


SWUpdate can be built just with the utilities in poky (since dunfell),
that means libubootenv.

PREFERRED_PROVIDER_u-boot-fw-utils = "libubootenv"

Best regards,
Stefano Babic

Hi Stefano,

I resolved my problems with swupdate compile, at the moment when I try to update my system with a swu image I receive this error:

[TRACE] : SWUPDATE running :  [parse_bootloader] : Bootloader var: booted = 0

[TRACE] : SWUPDATE running :  [parse_bootloader] : Bootloader var: tried = 0

[TRACE] : SWUPDATE running :  [parse_bootloader] : Bootloader var: primary = 1

[ERROR] : SWUPDATE failed [0] ERROR core/parser.c : parse : 281 : bootloader support absent but sw-description has bootloader section!

How can I enable bootloader support on defconfig?
I Have already set CONFIG_UBOOT=y

Thank you
