Hi,
Currently I working with Nucleo-H7S3L8 board and trying get XSPI interface up by trying to read memory device ID in STR OPI mode. It is not working yet.
Can someone share detailed steps to get it to working stage? I am able to read id in single SPI mode.
Thanks,
Samiksha

Hello,
you'll probably need to send a command to the memory to switch in OPI mode before sending the OPI ReadID command. Please check the memory documentation.

Hi,
Could you please point me to the specific command to put memory in OPI mode. I am not able to find one.
I tried to configure RDCR2 for STR OPI mode. Are you talking about any different command?
Thanks,

Not sure, because you don't specify the memory you're using.

Hi,
I am using MX25UW25645G memory which is already available on Nucleo board.
Let me know if you need any more details.
Thanks,
