How to upload touchgfx design to M29W256GH nor flash?

[JJung.6]

I am trying to load the m29w256gh nor flash on the stm32f429zi mcu.

I'm trying to create an external loader file, please advise.

I checked the m29w128g sample, but the MCU and 256g model are not compatible. help me =(

Well I'd recommend you start by creating/testing a BSP for the M29W256Gx on your own board, including the write and erase functionality. Then you can either port that to an External Loader, or implement your own loader/boot-loader which can take a .HEX or binary transmission, via USART for example, and program that content directly into your NOR Flash.

ST has examples, videos and tutorials.
