According to the errata sheet the LPC4350(A) has a problem with serial flash devices that uses 4 byte addressing.

The S25FL512S supports 24 bit addressing mode for legacy applications, but is this good enough to allow the LPC4350 to boot ?

As I understand it, the SPIFI interface can later be configured to correctly use 32 bit addressing, so if booting was possible I could just reinitialise the SPIFI interface while running from internal RAM.
