Compile the application via `cargo build --release`.\n\nPerform these steps\n- `esptool --chip esp32c3 elf2image target\\riscv32imac-unknown-none-elf\\release\\esp32c3_ota_experiment`\n- `cp target\\riscv32imac-unknown-none-elf\\release\\esp32c3_ota_experiment.bin firmware.bin`\n\nChange `THIS_VERSION` in `main.rs` back to `1`.\n\n## Run\n\nRun `devserver --address 192.168.2.125:8080` in a separate terminal (in the project directory). Make sure to replace `192.168.2.125` by the IP of your PC.\n\nTo avoid problems run `esptool erase_flash` first. Now run the application via `cargo run --release`\n\nThe application should connect to your PC, pick up `current.txt` and see it's own version (1) is below what is available online (2).\nNow it will download `firmware.bin` and flash it. After that it will set the OTA partition to use.\n\nIn this experiment the reset isn't done automatically. Reset the ESP32-C3 and see the new version boot.\nThe new version will see there is no later version online to flash.\n\n## Please Note\n\nMake sure to use the provided bootloader and partition table.\n\ni.e. when flashing manually with espflash use `espflash --bootloader bootloader.bin --partition-table partitions.csv`\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbjoernq%2Fesp32c3-ota-experiment","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbjoernq%2Fesp32c3-ota-experiment","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbjoernq%2Fesp32c3-ota-experiment/lists"}
