Pro Trinket verification errors on OS X

Post by barbar »

When I try to upload a large sketch (~20k) to my 3v Pro Trinket via FTDI on OS X, I'm getting verification errors:

Code: Select all

Binary sketch size: 19,400 bytes (of a 28,672 byte maximum)
avrdude: verification error, first mismatch at byte 0x0216
         0x69 != 0xff
avrdude: verification error; content mismatch
When I load a smaller sketch, like Blink, it loads without issue. I've seen this topic (http://forums.adafruit.com/viewtopic.php?f=22&t=45960), but it only seems to apply to Windows, and not OS X. Does anyone have any ideas?

Have you tried other USB cables? We see LOTS of issues with cables.

I tried a new USB cable and a new port on my USB2 hub. So far, so good. Hopefully this problem is solved. Thanks for the advice!
