Hello
I am building a RepRap and I have been trying upload my sprinter firmware to my sanguinololu and I encounter with this message:
avrdude: stk500_recv(): programmer is not responding
Please I need help. A friend uploaded the firmware from windows and worked good. I am using Ubuntu 10.04, arduino 1.0.1 and sprinter 1.3.22T
Excuse my english, I am colombian and I almost does't learn english.
