Creating and Uploading a Custom Filesystem to ESP32-C3

[pablogventura]

Hello MicroPython Community!

I’m currently working with an ESP32-C3 module and am facing an issue while trying to prepare a binary file for the filesystem pre-loaded with specific files for production use.

I've successfully downloaded the default filesystem created by MicroPython and accessed it on a Linux system using the littlefs-tools Python package, with a block size of 4096 and block count of 512.

However, when I attempt to create a new filesystem partition on Linux to upload to the ESP32-C3, MicroPython reports a corrupted filesystem with the following message:

The filesystem appears to be corrupted. If you had important data there, you
may want to make a flash snapshot to try to recover it. Otherwise, perform
factory reprogramming of MicroPython firmware (completely erase flash, followed
by firmware programming).

The command I’m using to generate the littlefs image file is:

littlefs_create -b 4096 -c 512 -s fs_content/ -i fs.bin

And for uploading the created partition to the device, I use:

esptool.py -p /dev/ttyUSB0 -b 460800 write_flash 2097152 fs.bin

Could someone please guide me on the correct procedure to create and upload a filesystem that MicroPython will recognize without errors?

Thank you in advance for your assistance!
