I just bought a RedBoard Artemis and I cannot upload any sketches to it. Whenever I try, I get this error: “avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00”.
I have tried two different computers and three different USB cables. In addition, the serial loopback test works. While there is power (either via USB power or via a barrel connector), the power light does show, and LED13 does blink.
Is it possible that the bootloader is trashed even though LED13 is blinking?
I don’t know why I couldn’t find this page myself. I see now that there’s a link to it from the Artemis product page, so I don’t know how I missed it.
In addition, I had to update the bootloader. I don’t know why both of my brand-new Artemis boards came with an outdated bootloader, but they did. That information is definitely not documented anywhere.
