How to configure RT116x FlexSPI with two flash chips

[kyle81]

Hi 

I am using FlexSPI1 A1 as XIP flash and another nor flash is connected to FlexSPI2 B1. 

Could you help my questions:

1. Can FlexSPI 1 A1 and FlexSPI2 B1 work together? XIP use FlexSPI1 A1, and our file system use flexSPI2 B1.

2. For FlexSPI2, we only connect flash to Flash B1,  Flash A1 and Flash A2 are not used. In this case, how to configure flexspi? Is there any sample for reference?

Thanks very much

Hi @kyle81 ,

1. Yes, they can work together.

2. I think it should be  easy for you to XIP from the  FlexSPI1 A1. All the examples in SDK boot from here. For FlexSPI2 B1, you can configure it in your application. But there isn't such a demo. You can start from  the flexspi demo in SDK.
