In the document AN4947 - Understanding Vybrid Architecture, figure 1, depicts a QuadSPI-0 and a QuadSPI-1. I could not find within the documentation much information on the QuadSPI-1. The idea is to use the QuadSPI-0 as an interface for 2 serial flash, while the QuadSPI-1 as an interface for a FPGA.
Can both QSPI-0 & QSPI-1 be used simultaneously? Are there any restrictions? Any special considerations when using QSPI-1?
Regards,
Flavio

Dear Flavio!
Please, take a look at the Re: Parallel QuadSPI and Re: Can Vybrid boot from the only QSPI_B? threads and let me know if you still have any questions.
Attached is also an excerpt from one of the Freescale designs with 3 QuadSPI (QSPI) memory chips used.
