Is it possible i want to put my .c files to SD Card? I want to read that .c files on SD Card.

I am working on httpd server project. My website codes are high memory (200MB). I converted my html/css codes to C file (fsdata.c). My C files now 200MB. I want to use SD Card for reading to C files. How can i do it? My SD Card 2GB.

You'd need to add in SDIO/SDMMC and FATFS code to access the card, and them modify the file system code that deals with the fsdata so it recognizes a path that has files on the card, and then pulls and sends that data.​

[KAnahar]

do you have example code?

You don't want fsdata.c on the card for the web server. You want the binary data.

I write code for a living...

Suggest you start by porting one of the CubeF7 FATFS+SDMMC examples to your board. Once that works find an appropriate point in the LwIP server code to integrate reading from the the media via the FSDATA structures.
