Part Number: AM4372
Sitara support team,
I would like to make sure that the following NOR Flash Memory can use a qspi boot for AM4376.
I have checked Section 188.8.131.52.1.in AM437x TRM and there is described...
-The boot device must default to quad mode, if quad-read support is desired
However MT25QL512ABB1EW9-0SIT is set "Quad I/O protocol" bit in Nonvolatile Configuration Register is "1 = Disabled (Default)".
Is this problem for using the NOR Flash Memory? Or is it not problem to use if "Quad I/O protocol" bit is set "0 = enabled"?
If there are any other limitations to use the NOR Flash Memory, please let me know.

Yes, this is a problem. AM437x will not be able to boot from this memory.
KanaeOr is it not problem to use if "Quad I/O protocol" bit is set "0 = enabled"?
If this is set BEFORE the AM437x tries to boot from this memory, then the boot will be successful.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
