Question about Using HyperRam and HyperFlash

[ChekhovMark]

Hi, I have some problems developing an I.MX 1052 application. I need more GPIOs, and flash speed is critical. so I'm thinking about using HyperRam and HyperFlash instead of QSPI Flash and SDRAM. Is it posssible to mount both HyperRam and HyperFlash simultaneously on one flexSPI instance, and XIP boot from HyperFlash? If I do so, will the access speed drop when accessing RAM and FLASH together?

Thanks.

Hi Chekhov Mark,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1)  Is it possible to mount both HyperRam and HyperFlash simultaneously on one FlexSPI instance, and XIP boot from HyperFlash?
-- No, I'm afraid not.
For the MIMXRT1052, it's capable of working with the HyperRam and HyperFlash simultaneously, as it has the FlexSPI A and FlexSPI B.

Have a great day,
TIC
