STM32H7A OCTOSPI / HYPERRAM Disabled in STM32CubeIDE

Hello all, I have a fundamental question, I hope it is easy for somebody who has done this before.

I started a brand new project for a STM32H7A3VITxQ on Firmware package FW_H7 V1.11.2

STM32CubeIDE
Version: 1.16.0
Build: 21983_20240628_1741 (UTC)

Updated the clock to 280 Mhz (max allowed), and tried to enable OCTOSPI2 for HyperBus (or Octo SPI) but these options are not enabled.

Is there something that I'm missing to be able to enable OctoSpi or Hyperbus?

Hi,

maybe -- because octo is not bondet out on this package ? (only quad, see ds.) :)

Almost certainly, the LQFP100 chip lacks the necessary pins for HyperBus on OCTOSPI2.

You are right looks like the 100pin doesn't have IO7
