Example of using FAT with ESP32
Features
- prepare of FAT image
- flash FAT image to ESP32
- example of FAT functions
Configure your esp32 build environment as for other esp-idf examples.
Clone the repository:
Code: Select all
git clone https://github.com/jkearins/ESP32_mkfatfs.git
Code: Select all
make menuconfig
Code: Select all
make all && make flash && make flashfatfs
FAT image can be prepared on host and flashed to ESP32.
Tested and works under Windows. It is not tested under Linux and Mac OS yet but should work.
Copy the files to be included on FAT into components/fatfs_image/image/ directory. Subdirectories can also be added.
To create FAT image in build directory without flashing to ESP32 execute:
Code: Select all
make makefatfs
Code: Select all
make flashfatfs
Code: Select all
make copyfatfs
- registers FAT as VFS file system; if the fs is not mounted the system will halt
- lists files in root directory

Files for sample flash image have been gotten from another Kolban's project https://github.com/nkolban/ESP32_Explorer.git introduced there https://esp32.com/viewtopic.php?f=17&t=2977
