I bought some RBBB(w/atmega 328) and usb-ttl conversor board from modern-device . I'm using arduino-17 IDE, ubuntu-linux (board: Duemilanove or nano w/atmega 328, port: /dev/ttyUSB0). I play with other arduino boards (mega, seeeduino) and all works ok.
First time i upload a sketch to the RBBB all works ok, i tested the sketch and runs ok inside the RBBB. After that i can't upload more sketches to the same RBBB and show the messaje:
avrdude: Send: 0   avrdude: Send: 0   avrdude: Send: 0   avrdude: Recv: .  avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: Send: Q   avrdude: Recv: .  avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00
I reheat the soldering joints on the BUB headers and RBBB header. I saw the chip is firmly seated in socket.
I tested reset button and works ok.
I think it's about auto-reset... but i dont know..
I tried it two differents RBBB boards, with the same results. upload proccess fails after the second time.
suggestions are welcome
pd: sorry about my poor english skills.
