This repo is to test the implementation of SPIFFS in epsrs

Prerequisits

To successfully compile and run this program you will need to have the following things installed:

• python3,
• esptool.py,
• espflash cli
• esp-idf,
• esp-rs,
• rust toolchain

espflash

Can be instlled easily enought via cargo

esptool.py

Can be installed via pip install esptool.py

esp-rs

For the proper installation of eps-rs the tutorial on the website should be followed. I would recommend installing for both xtensa and RISC-V targets, but this project only supports RISC-V

Development environment

I use vscode for most of my projects. I recommend having rust-analyzer installed. The only other thing to do before writting code is to add the following lines to your .vscode settings.json file:

{
  "rust-analyzer.check.allTargets": false,
  "rust-analyzer.cargo.target": "riscv32imac-esp-espidf"
}

This adds all the generated bindings to intelisense autocomplete. Please note though that this config only works for riscv targets (riscv32imac-esp-espidf)

Running and flashing

To flash filesystem and new partitions to device run the flash_spiffs.sh script

./scripts/flash_spiffs.sh

To flash chip and monitor it run:

espflash flash target/riscv32imac-esp-espidf/release/esp-rs-fs-test --monitor

To only monitor run:

espflash monitor

Things to keep in mind

When adding a spiffs storage partition it has to be added to the partition table with subtype spiffs, and the partition table on the device needs to get reflashed.
