Hi Sir,

I have two SPI devices on our board,

one is an XSPI flash for NXP U-BOOT & KERNAL use, and the other one is a QSPI device.  

Q1.Can I use XSPI_A of LX2080A to connect them?

Q2. Can these devices be worked together?

the simple connection topology is shown as below:

A1. The connection looks fine. However, the SW need to know one is 8 bit data line vs 4 data lines.
A2. I do not know what do you mean whether these devices can be worked together? The commands send to these two flashes should be different as one should be x8 another should be x4.
