As far as I read datasheet it says there is a support for that, but in STM32CubeIDE under FMC I cannot select NAND. There is simply no option for that. See attached file.
It appears that there is only one NAND chipselect, NCE3, and that is not present on the 100-pin package. The footnote to Tab.2 in DS10693 Rev 7, mentioning NCE2, is probably copy-paste from the 'F40x datasheet.
@Imen DAHMEN , can you please have a look at this issue? Does the 'F446 have FMC_NCE2 or not?
I raised this internally for check and will come back to you with update.
