getting avrdude error when uploading sketches

Hello,

I also encountered this error while uploading the Esplora Temperature Sensor example:

“Binary sketch size: 6,472 bytes (of a 28,672 byte maximum)
Found programmer: Id = "B«f"; type = “
Software Version = . ; Hardware Version = .
avrdude: error: buffered memory access not supported. Maybe it isn't a butterfly/AVR109 but a AVR910 device?”

What could the problem be and how can I correct this?

I also noticed that the Serial Monitor closes as soon as I start to upload the program.
How can I correct this?

Also I want to know does the board already have an inbuilt temperature sensor, or do I have to connect a physical temperature sensor for the program to work?

Thank you.

David.
