STM32H5 support for MX25L6433F

[Kostas Papouis]

Hello Everyone,

Is there any plan for ST to provide support drivers for the MX25L6433F serial NOR flash on the STM32H5 series of micros?

MX25L6433F is the flash used on the X-NUCLEO-GFX01M2.

Thanks.

MX25L6433F is also used in the X-NUCLEO-GFX02Z1 and it provides quad SPI.

Hello @Kostas Papouis ,

I will escalate your request to the appropiate team through internal ticker number: 178608.

Meanwhile, you can create your own external loader by following the steps described in UM2237 (in 2.3.3 Developing customized loaders for external memory section).

You can refer to this post which contains a useful link of MX25L6433F files (shared by Tesla).

Hello Imen and @Tesla DeLorean ,

I did research this and I think there are two options to generate an external loader on the STM32H562RGT6 and MX25L6433F?

1st option - Migrate the NUCLEO-U575ZI-Q flash loader project that is located at:

STM32Cube\Repository\Packs\STMicroelectronics\X-CUBE-DISPLAY\3.0.0\Projects\NUCLEO-U575ZI-Q\Applications\GFX02Z1_FlashLoader

This application is using the MX25L6433F.

 

2nd option - Use the stm32-external-loader  contrib files to generate a the external loader. However I am not sure the drivers at the contrib repository are compatible with the STM32H5 series .

Could you please confirm which is the best option?

Thanks.

I suspect the first option would probably be the easiest port.

I've built an H5 - MX25L / W25Q loader.

Do you have an enumeration of the pins you've used?
