The BBT gets created automatically if it does not exist, provided the NAND controller driver asks for it. Why do you need an explicit command?
I do not necessarily need an explicit command. I wanted to rebuild NAND BBT after scrubbing it. Is there another way to do that?
It should happen automatically when nand_erase_opts() calls chip->scan_bbt(), provided the driver set the NAND_USE_FLASH_BBT flag, and that NAND_BBT_CREATE/NAND_BBT_WRITE are set in the nand_bbt_descr (this is the case if the driver doesn't override the default nand_bbt_descr).
Are you not seeing it happen? What version of U-Boot are you using, with which NAND controller driver?
