Unless I am understanding it the wrong way, NAND_SKIP_BBTSCAN will skip the scan of the on-chip BBT and will scan every block to construct a RAM, based BBT thanks to the BBM. So flash based BBT is already unused and removing this flag is a mistake, right? > Flash based BBT is not used since bootloaders > doesn't have support for the same. > > Signed-off-by: Abhishek Sahu > --- Thanks, Miquèl
