Hello Ito,

Thank you.

Can you confirm if you are looking to interface to x3 devices on the OSPI0 interface.

We have seen customer interface x2 device using bus switch.

Hello Ito,

Please refer below links for information on using the OSPI0 to interface to x2 attached devices.

A tiny documentation: https://github.com/TexasInstruments/Beyond-SDK/blob/main/am243x/examples/ospi/ospi_psram_io/am243x-evm/r5fss0-0_nortos/Docs/README.md

The entire code base which the customer can refer to in order to know how the switching can be done: https://github.com/TexasInstruments/Beyond-SDK/tree/main/am243x/examples/ospi/ospi_psram_io/am243x-evm/r5fss0-0_nortos

Please note the testing was done on an internal test board derived from the EVM.

→x3 devices. QSPI Flash×2, and FeRAM

→That example is very interesting.
Is that an example using AM64?
Could you tell me more about it?

Did you run the sample evaluated on a board derived from AM243 EVM?
