OK, finally built the u-boot-fw-utils and run it on iMX6ULL:

# fw_printenv -v Compiled with U-Boot 2019.07-dirty

But it could not run:

# fw_printenv Cannot read bad block mark: Invalid argument

Here is the configure file:

# cat /etc/fw_env.config

# NAND /dev/mtd1 0x400000 0x100000 0x20000 8

I think values in configure file are correct:

# cat /proc/mtd dev: size erasesize name mtd0: 00400000 00020000 "boot" mtd1: 00100000 00020000 "ubootenv" mtd2: 0fb00000 00020000 "storage"

=> nand info

Device 0: nand0, sector size 128 KiB Page size 2048 b OOB size 64 b Erase size 131072 b subpagesize 2048 b options 0x40004200 bbt options 0x00000000

Any advice what I could be missing?

Thank you.

Kind regards,

on Zeus it's very likely _not_ libubootenv that you need, you should try to install u-boot-fw-utils. As Yann wrote, the tools are in libubootenv since Dunfell, which is newer than Zeus.

Thanks Nicolas, I have following error, what I could be missing here?

ERROR: Task (/build/oe-core/meta/recipes-bsp/u-boot/u-boot-fw-utils_2019.07.bb:do_compile) failed with exit code '137'
