Creating STM32N6 ioc project for hexaspi and octopus pi.

darla14 · ‎2025-09-23

Hello,

While creating a project for STM32N6 I can’t find the option for hexaspi or octospi for STM32N657B0HxQ . Is there any particular option I have to enable?
I am trying to generate the ioc similar to STM32N6570-DK board .
I am on 6.15.0 STM32CubeMX.

Where is octo and hexaspi option?

also which mode I have to enable FSBL + Non Secure/Secure or only Non Secure/Secure

Best Regards,

D

Hello @darla14 ;

According the STM32N657 datasheet, the STM32N657B0HxQ supports only 2 XSPIs 8 bits (OCTO) and not 16-bits (HEXA)

For the Octo SPI mode, you need to configure the XSPI with Octo SPI mode.

Thank you.
