Coprocessor Firmware Update
The ESP32-C6 coprocessor firmware can be updated over-the-air using the esp32_hosted update platform:
update:
- platform: esp32_hosted
name: "C6 Coprocessor Update"
path: /path/to/network_adapter.bin
sha256: your_sha256_hash_here
The firmware binary is embedded into the ESP32-P4's flash at compile time and can be deployed to the coprocessor on demand. The component automatically detects the current firmware version and compares it to the embedded version. If they differ, an update becomes available in Home Assistant.
