I need to put it my web codes (html, css, js) to SD Card. Also These codes need to work on SD Card. Because my web codes memory size is around 300MB. Normally I worked my code (basic html files) without SD Card. It needs converting to fsdata.c files. I have 'makeFSdata.exe' file. When I change to HTML codes, I click and work .exe file. Then build my project.

How is it possible with SD Card? All web site folders need to work on SD Card.

Hello there,

Are you using on an STM32 provided board or your own custom PCB? Did you check for example projects for when servers and interfacing with uSD cards?

Some inspiration:

Should be possible to integrate SDMMC and FATFS support, and get the serving routines to pull the data from files directly rather than the fsdata methods.​
