ESP32C3-DEVKITC-02 original firmware

[DanSkareda]

Hello. I have an ESP32C3-DEVKITC-02 development board and so far I upload projects to it via USB using the Arduino IDE. It works correctly. But now I would like to load the firmware in the bin file by pressing BOOT and RESET after turning on the development board (I have the firmware - it was created for me by esphome in the home assistant). My question is, if I flash the firmware of the board with a "bin" file via USB, where can I find the original firmware so that I can upload again later from the Arduino USB environment? I couldn't find the original firmware (which was in the board when it was sold) anywhere, and I don't know how to download it from the board. Thank you for the advice or explanation.

I don't think the Arduino IDE needs any special firmware/bootloader on the chip in order to upload via USB. On the C3, the USB upload capability is built into the chip's hardware and ROM bootloader.
