We originally had a NAND part on our design but have successfully been able to boot and run from SD. I want to remove the NAND part, supporting parts, and associated traces from the design.
That will leave all the data lines and the 7 other control lines floating. It looks like most of the control lines (oe, we, ce, cle, ale, etc) are outputs, so I should be fine to just let those pins float - right?
What about the data lines and em_wait (J18 pinmuxed with GPIO and HPI)? em_wait has an internal pullup; can I just rely on that?
(I'm just nervous to completely remove this. There are pullups on several of the control lines (oe, we, ce).)
I've checked all the docs I can find and there doesn't seem to be any mention of what to do with these lines. Any help of course will be appreciated.
Thanks,
David Havell
