PROCESSOR-SDK-AM64X: is it possible ? ospi rebase to 1s-1s-1s mode and become spi

Hello,

Are you using Linux SDK or MCU+SDK?

hi, mcu+sdk.  no os

I know ospi controller is degined for the nor flash.   

That is incorrect.

On AM64x you would see the design for NOR flash as AM64x TI EVM has a NOR Flash Part.

But if you look at TI EVMs having NAND Flash Parts like AM62A, then you would see that the OSPI controller is also supported for NAND Flash Parts.

Also is your question as follows? Do you want to know if you can go ahead and use MCSPI or OSPI in 1S-1S-1S mode?

Hi Vaibhav:

Thanks for explain it to me. 

I mean for me I don't want to use OSPI for video streaming.  I will send h264 via ospi to another mcu.  another mcu is using spi protocol and display the video.  is that OK?

or I have to use MCSPI? (I tired MCSPI, it works fine.)   But never tried with OSPI, will it work for ospi?


Thanks.

You can stick to MCSPI.

I want to increase my knowledge, can I use ospi also in theory in my video streaming case ?  Can you confirm with me "yes, it is possible." Thanks.
