S32K358 HyperRAM demo

[CherryDeng]

We need run someip software stack in RAM, it need more than 2MB size, so need extend RAM on S32K358, we want to design HyperBus with 8 line HyperRAM, do you have some demo example for this? Thanks.

Just noting following two features are necessary for HyperRAM memory, so S323K358 derivative is capable of that.

As I know there is not dedicated driver, but there is Qspi_Ip_Example in the S32DS. So this could be used as a base, possibly.

I am not sure if you mean example of connection or code example.

We try to avoid recommending specific devices to customers for memory and other external components. Because of the large number of choices out there it is impossible for us to have hands-on experience with all of them, and we don't want to recommend devices that we haven't used ourselves. We are at least indirectly recommending devices by including them on our EVBs and reference designs. So in most cases our best recommendation is to use the devices we have used or at least find something similar that will meet your specific needs.

There is an appnote dealing with QuadSPI:

QuadSPI is highly configurable module because it uses look-up tables for SPI commands what should theoretically allow user to adapt the code to any SPI memory.

S32K3X8EVB-Q289 uses S26KL512SDABHV030 device what’s HYPERFLASH device i.e. octal SPI flash memory connected with HyperBus protocol.

It is expected memory mapped access and driver is a part of RTD FLS drivers pack (real-time time flash driver, supporting internal flash as well as QuadSPI):
