Random Reset of Arduino due board Rev 3

14 Apr 2024

Dear Community members,

I m working on Arduino due board Rev 3 version. I have observed that this board gets reset in Random fashion . I unable to find out the reason. If Somebody who has worked more extensively than me on this board,might help me.

I have chosen just one I/O pin to check to blink led connected with 1k resistor in series on PIN NO 40 . i have written small program in Segger Embedded Studio to blink LED. LED was blinking correctly but I have noticed small blip on LED marked 'L' meaning it glow randomly for very small period of time when MCU ATSAM3X8E receives reset . Also when i press reset button on Arduino due, "L" led glows.

Please! help me to debug this random reset issue. I don't have oscilloscope to debug since they are expensive.

i m sure that somebody might have encountered this issue before & also resolved the same.

PLEASE! HELP ME URGENTLY SINCE THIS ISSUE WILL INTRODUCING MORE DELAYS IN MY DESIGN.

Before you take a soldering iron to your board, you should carefully compare the issue described there, with the symptom that you observed. It does not match.

I was going to write a long reply about how to systematically do a board bring-up, but decided to write something a lot shorter.

Simply:

(1) Buy a second Arduino board (a lot cheaper than an oscilloscope, which is unessential for now) and use that to confirm if you have a board fault or not

(2) Use a second PC and second USB cable to confirm if you have a PC USB connection or cable issue

(3) Use the Arduino IDE (NOT Segger Embedded Studio) to run one of the example programs that are in the Arduino IDE, to confirm that software can run reliably

If (1), (2), (3) don't reveal any issues, then there's a great chance the problem lies in either your code, or the libraries or run-time you're linking together with, or your linker settings.

No. absolutely no. All caps are already soldered on board on evaluation kit.
