STM32MP157 FMC NAN,D NCE or NCE2 ?

[PMort.1]

I want to connect a SLC NAND to the FMC controller and boot from it

What CS* must i use (NCE or NCE2) ?

Why i got the "Pin not available for boot step" in CUBEmx when trying to select NCE2 ?

Hello,

only SLC NAND device connected using FMC_NCE is supported as boot source.

You could refer to related wiki page and AN5031.
