Does anyone have the external loader source files for the W25Q64JV on the STM32H743? If I have the driver file for the W25Q64 can I use the Dev_Inf and Loader_Src c and h files from another STM32H743 loader project?

I seen several loader project at this git hub locations but non are for the W25Q64 NORFlash with the STM32H743.

I have driver file already for the W25Q64 that I'm debugging a few issues now. Once I have those resolved can I create an external loader using these and the Dev_Inf and Loader_Src .c and .h file from another STM32H743 project to build an external loader or do they need to be modified for the specific NORFlash device as well?

If not does anyone have the loader source file need for this device?

Yes, having a working BSP is a good starting point for building/porting an external loader. That way you can debug more easily. Debugging an external loader can be a challenge, best course there is to instrument using functionality of your board (uarts, leds, etc) so you can understand what's happening.
