External Loader support for STM32U5 + Winbond W25Q128 (OCTOSPI)

[Harp0309]

Hello,

I am using STM32U5 with an external Winbond W25Q128 (Quad SPI NOR via OctoSPI).

Could you please clarify from where an external loader (.stldr) for STM32U5 OctoSPI NOR can be obtained, if available?

I checked the following locations and did not find any loader for STM32U5:

• STM32Cube_FW_U5/Utilities

• STM32Cube_FW_U5/Projects

• STM32CubeProgrammer default ExternalLoader directory

Is there an official external loader provided by ST for STM32U5 + OctoSPI NOR, or is it currently not supported?

Thank you for the clarification

Hello @Harp0309 and welcome to the community;

You can find the external loader (.stldr) files for STM32U5 boards with OctoSPI NOR FLASH memories in STM32CubeProgrammer toolchain.

Also you can find some projects source in  stm32-external-loader/STM32U5x_boards at main · STMicroelectronics/stm32-external-loader · GitHub.

I advise you to look at this How to implement and use your own external flash loader: An example using STM32U5A9J-DK may help you.

Thank you.
