atmega32u4 breakout board malfunction ?

Post by cclauz »

Hi, just received my atmega32u4 breakout board:)
But it doesn't seem to work as intended, first the boot led is red and the pwr one is green, on the photos I see it looks like it should the opposite.
The other more serious problem is that the boot led never stops "breathing", I can see the ACM0 tty, upload my code thanks to avrdude, but the code never seems to execute.

I followed the tutorial here: http://forums.adafruit.com/viewtopic.php?f=24&t=23266

Thanks.

You're using linux?

Pressing reset doesn't change anything? The LED just keeps breathing? What about if you cycle power to the board? Is it still stuck breathing?

Hi,

Yes I am using linux, reset button doesn't change anything, tried cycle power, still breathing.

I actually have a avr-isp500 programmer, I think I'm going to try reflashing the bootloader, seems like I don't really have a choice, right ?

thanks,

You can try that. Or we can replace the board. Please email [email protected] with a link to this thread for a replacement
