Hola.

Tras recargar micropython en Alvik con Micropython Installer y reiniciar el dispositivo, Arduino Labs for Micropython no lo reconoce y no puedo cargar código en él.

Si utilizo el IDE de Arduino sí que reconoce el dispositivo.

Cuando pulso el botón de conectar en Labs me muestra un puerto COM y la opción de actualizar, pero al seleccionar el puerto solo se obtiene el mensaje de que está cargando archivos.

He repetido el procedimiento varias veces y no logro que Labs reconozca la placa. ¿Alguna sugerencia?

Gracias.

Saludos.  
Estaba probando a hacerlo con el instalador, que parece que instala todo sin problemas pero luego no hay manera de conectarse con el IDE de micropython.  
Trabajando sobre Mageia Linux 9 instalo mpremote en el ordenador. Me advierte de que puede haber problemas si se ejecuta como administrador:

```arduino
pip install mpremote
Collecting mpremote
  Downloading mpremote-1.23.0-py3-none-any.whl (27 kB)
Collecting pyserial>=3.3
  Downloading pyserial-3.5-py2.py3-none-any.whl (90 kB)

WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv

```

Me ha dejado instalar la biblioteca:

```arduino

```

Pero se eterniza actualizando el firmware tanto de usuario normal como de administrador:

```

Con mpremote he podido subir los archivos de la demo estándar, pero sigue sin conectarse a la placa Arduino Lab for Micropython.

En resumen, el robot funciona 😀 (gracias), pero el interfaz sigue sin reconocerlo 😢 .

Por si sirve de algo, esto es lo que ve el sistema operativo (Mageia Linux 9) cuando pincho Alvik:

No sé si aporta información que el LED de al lado del botón de reinicio del chip parpadea continuamente en rojo y el de al lado del puerto USB está fijo en amarillo cuando el robot está conectado al ordenador mediante el cable USB.
