Did I fry my Xboard Relay?
geraldl 2013-11-19 07:33:41 3300 Views2 Replies I have one Xboard Relay that does not get recognized in IDE nor Windows. The bootloader com port(com15) and then disappears. Then I would get the Leonardo com (com16) that stays. I understand that the bootloader appears as a separate com port and then the Leonardo shows up afterwards. NOw the bootloader com appears and then disappears but no leonardo. Is there anything I could do? Is this still hope since I temporarily see the bootloader com port? Luckily I had a spare xboard, but I would really like to save this one. Thanks for any help.

Hi Geraldl!
Send the last sketch you uploaded on the xboard?
And a picture of your hardware, with modules attached if any, and the power supply used.
Cheers

Hi Jose, this was the last thing to be uploaded. I am only using a usb cable for power. No modules installed, once they get going I read a voltage on the analog in channel. You may notice, I had to replace a diode previously, but it worked great after that. It was basically after the upload of the sketch the problem occurred. I am not sure if it completed, even though the IDE did say so. After the uP reboot it hung. I do have other (7) Xboards and they work with the sketch. It's only because I only have this one left to play with since the others are in use and I would like to keep this as my spare. I am hoping to maybe only have to upload factory firmware (bootloader). Thanks for the help.
