Embedding a flash loader into custom application. Any example projects out there?

[AjcEng]

External FMC NOR Flash for large Touch GFX files.

Is it possible to embed the flash loader into a custom application? (Build it into the base hex file.)

I wanted to forgo using the typical .stldr method for firmware update reasons

Are there any example projects I could be directed towards for this?

Any help is much appreciated

Thanks

There should be some chip level code in the BSP, at least for Micron and Macronix parts.

You could use MicroSD (SDIO/SDMMC) as a delivery method.

Perhaps also look USB DFU implementation examples.

Serial's probably too slow to entertain. Things like XMODEM could be used, relatively high baud rates might be possible.

An USB MSC might be workable for staging new content that you subsequently copy into active portions of internal / external flash. This could be in BIN or HEX formats.
