|-- Detected file type: UF2 - esphome 2024.12.4

|-- Connect UART1 of the BK7231 to the USB-TTL adapter:

| --------+ +--------------------
| PC | | BK7231
| --------+ +--------------------
| RX | ------ | TX1 (GPIO11 / P11)

| GND | ------ | GND
| --------+ +--------------------
|
|-- Using a good, stable 3.3V power supply is crucial. Most flashing issues
|-- are caused by either voltage drops during intensive flash operations,
|-- or bad/loose wires.
|
|-- The UART adapter's 3.3V power regulator is usually not enough. Instead,
|-- a regulated bench power supply, or a linear 1117-type regulator is recommended.
|
|-- To enter download mode, the chip has to be rebooted while the flashing program
|-- is trying to establish communication.
|-- In order to do that, you need to bridge CEN pin to GND with a wire.
|-- Unknown bootloader CRC - 0x698E014A - please report this on GitHub issues!
| |-- Success! Chip info: BK7231N
