STM32H5 does not have a DQS line for HYPERBUS

burakOnemli · ‎2024-09-21

Hello everyone,

I was trying to design a Hyperbus RAM based PCB for one of my projects but I realized that when I configure Hyperbus under the OCTOSPI1 settings I do not get the DQS(RWDS) line. Here are the configuration pictures.

Thanks,

Burak Önemli

Granted it's only been about three hours since your post... :)
