## Build the library and command line utility

For building `blisp` command line tool, use following commands:

```bash
mkdir build && cd build
cmake -DBLISP_BUILD_CLI=ON ..
cmake --build .
```

# Usage

For BL70X, BL61X, BL808 and BL606P, connected via USB, you can use following command, which will auto-detect serial port:

```bash
blisp write --chip bl70x --reset name_of_firmware.bin

For BL60X, you need to specify also the serial port path:

```bash
blisp --chip bl60x --reset -p /dev/ttyUSB0 name_of_firmware.bin
```
