Huzzah exception on start

Post by spatel4140 »

I recently ran into a problem with the huzzah board. I ordered 3 of them about a month ago but just recently began working on them. One of them seems to be acting out of the ordinary.

They've all been uploaded with the same sketch. Two of them work flawlessly (so I know it's not a problem with the code) but when the defective one turns on, it automatically goes into the boot loading mode where the gpio0 led is half lit. What I assume is the TX led, the blue one that blinks when uploading a sketch, is also continuously lit on start. Both leds come on right away when powered.

The following error is repeatedly printed in the serial monitor:

Code: Select all

Fatal exception (0): 
epc1=0x40214834, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000]
Also, attached are pictures of the front and backs of the board.

Is this a known issue? I've searched a ton of blogs and forums without any luck. If there's anything you could do to help solve the problem, that would be much appreciated. I look forward to hearing back from you!

Your soldering looks excellent. If you have two others that work in the same configuration, we can call the one that doesn't a hardware failure.

Send a note to [email protected] with a link to this thread and your order number. The folks there will get you a replacement for the HUZZAH board that doesn't work.

Hi,

I've got the same issue here, except that the board worked for 2 month, and start to hang after (random reboot). I try to flash it again, but after reboot I have this :

Code: Select all

Fatal exception (0): 
epc1=0x4012b500, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000
Any clue on the subject ?

Try dropping back to the basic 'blink' sketch and see if it loads properly.

Sounds like a hardware failure then. Unfortunately, our return/replace period on runs 30 days.
