[OE-core] Failed to add u-boot ubifs (not working)

[JH]

Hi,

I added my local machine to ubifs, is it correct?

UBOOT_CONFIG[nand] = "mx6ull_14x14_evk_nand_config,ubifs"

I built the u-boot.imx, but the ubi was still missing in u-boot. What
I could be missing?

=> run nand-boot;
Unknown command 'ubi' - try 'help'
Unknown command 'ubi' - try 'help'

Thank you.

Kind regards,
