QSPI fast boot issues

We are using a Spansion S25FL127S QSPI part.  We are having difficulty on some units booting in quad mode using a 100MHz clock.  Are there any reported issues using this part with the Vybrid VF6?  It is quad SPI, but single data rate only.  We seem to be able to reliably boot in single data bit SPI mode at 100MHz, but quad seems to fail right after we command the part to go into QSPI mode.

 

Thanks,

 

John
