Guys,

Does R/B pin on Nand flash needed on the software ? I can't find R/B pin on GPIO definition, Anyone knows ? thanks #nand

I tried to run the function,

but I can't see any response on LED, not even a blink.....do I miss something here ? D0-D7 = GPIO push pull and CLE,NOE,NWE = Alternate Function Push Pull thanks

I'm using STM32F107 and NAND flash....

Look I'm not familiar with your design, or the software surrounding it, it's not my project. Does the 107 Connectivity Line even support the FSMC external bus? If you enable the clock bit for the FSMC in the AHB clock register does the bit stay set, or does it remain clear?

I think this table from datasheet is giving me a clear answer, thanks for the clue clive...

It's working already, thanks for helping, How can I use FatFS with NAND flash ?
