STM32H7R/S3x: using external QSPI as primary FLASH

[KDJEM.1 · Accepted solution]

Hello @simo zz,

I recommend you to look to these resources that can help you:

• GitHub - ST-TOMAS-Workshop/stm32h7s_workshop: stm32h7s workshop content
• Getting started with External memory Manager and External memory loader - stm32mcu
• Category:STM32H7RS - stm32mcu
• Introduction to STM32H7Rx/7Sx system architecture and performance - Application note
• Introduction to external memory manager and external memory loader middleware for boot flash MCU - Application note
• Getting started with Octo-SPI and Hexadeca-SPI Interface on STM32 microcontrollers
• Getting started with External memory Manager and External memory loader - stm32mcu 

Thank you.

Thanks @KDJEM.1,

I think I have enough info to proceed.

Accidentally I deleted the content of the first post but the question essentially was:

#1) If it's possible to use the QSPI/OSPI has primarly flash. I am pretty sure this is possile after looking at your links and AN5050 and AN4760.

#2) How to set up XPI and External loader, but NUCLEO-HS73L8 has a setup for this purpose so I can look at it.

Thanks.

Cheers,
