Anyone Have stability issues with Arduino Uno Q?

SensoredHacker0
SensoredHacker0 1 month ago

So im at my PC typing away. The Uno Q ran my code on the first try on the first day i got it, a couple days ago.
made some more tests, for 2 days everything was working great. Then, without warning, did not move it, or touch it, it stopped.
ok fine I guess. Then I tried to upload new test code. it compiles, and claims to have been uploaded. but the code doesnt work. 


The hardware which was attached, when it failed:
a Max33041E shield, and the Ethernet R3 shield. these had been working for a couple days straight. 

Not like the code is buggy, but like it doesn't even init the serial print lines. 
bash my head on the wall for a while. 
Press Reset. nothing. Un plug it, wait, re insert usb power.
$dmesg shows it, loading without issue.  

Pull the shields off, load blink. same thing, it compiles, and claims to upload, but the code never runs. 

I haven't reinstalled the boot-loader, by the time I thought to try that, I'd already gone to bed. 
But I've never had such random problems before. Ive got arduino running in projects that have run for 6 years straight not problem.

besides reloading the bootloader and one have some ideas?


Are there stability issues with the Arduino Uno Q I should know about?

Perhaps the most frustrating thing was that the LED matrix was making little hearts and arduino logos the whole time. 
meanwhile blink wont run.

    I'm glad you guys are investigating the Q and working through the issues. It will help everyone. However, got to strongly disagree with this: The Q can't really be expected to be compared reliability…

    The Q can't really be expected to be compared reliability/stability wise with previous Arduinos. With the new hybird MPU/MCU structure it is going to have a lot more issues than the MCU only boards. I…

    I agree with your comments, but just to clarify what I meant - the Q has much more complexity and many more points of failure, both in hardware and software. I do think the current implementation is faulty…
