Anyone Have stability issues with Arduino Uno Q?

SensoredHacker0
SensoredHacker0 4 months 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…

    That's concerning. Q has so much potential, but it's currently let down because of (it feels to me) lack of focus by Arduino. If it's going to stop starting up correctly after some power cycles, then it just won't get used, people will switch to other control boards. They have to take this seriously and eliminate such flakiness from the software/OS build or hardware, this to me is a showstopper, otherwise no-one can trust using it. I bought a Q to try it out, but will wait till it's more mature (hopefully). Also, a few of the other Arduino boards have at least perceived problems, since Mbed is EOL very shortly, and I wonder how long till any replacement Arduino libraries will be reliable. Think Arduino needs to have better messaging at a minimum, so users are not in the dark.

    Arduino has switched to using Zephyr RTOS: https://github.com/arduino/ArduinoCore-zephyr

    Still a long way to go to get to version 1 - they're at version 0.55.

    My guess is that it'll go version 1 once the next Zephyr LTS version is released next year.

    I hope they hurry up. That's a long time to be unsure if things will be stable and if the API or subtle behavior will change.

    Sad to say that it appears right now for an amount of networking capability, one might want to simply walk away and consider non-Arduino boards, unless they pull their socks up.

    I think by default you still use MBed. You need to manually switch to the Zephyr option. Personally, having persevered with getting to know Zephyr RTOS, I find it really good.

    If you are using the Q, the default is using Zephyr - both in AppLab and the standalone Arduino IDE.  Creates problems with legacy hardware because some (many?) third party libraries are not updated.  I ran into problems with the Arducam libraries.  Right now the only option is to port it yourself (a handful of class definition changes).  Hope the manufacturers will update their libraries to Zephyr soon.

    The standalone IDE does work with the Q, but I wouldn't recommend it.  Not sure what the real use case is.  I tried it because it is more familiar to me and I hoped to reuse code, but I don't think that Arduino is really going to support using software external to AppLab for the Q.  Have not investigated if it is possible to remove AppLab to get back the system resources.

    Ah right, I did not know that. Agree, many of the old libraries will simply do not work. It's a case of rethinking our old ways when doing things with Zephyr. Info is there. It needs understanding. That's tricky without tutorials.

    yeah the first thing I did was grab an arduino Mega, and keep on working on my project. but for 4 hours, I thought to myself this board is brand new, I literally havent touched,  it, was working, and now it doesn't work. The expensive dev board arent what I slap into projects. If I have to buy  a dev kit, to experiment on, Im not going to think ooh a 70$ arduino. Ill just pick up a 3$ Uno clone, and see where its lacking. If im putting an expensive devboard in something, I've already built the prototype. So Arduino is probably missing out on a lot of entry level development.  I could buy an Uno Q, but now I have some random fail as the first thing Im going to think of. versus this 15 year old arduino MEGA that has never failed even once. 

    We'll see I guess. Maybe a firmware update patches it. 
    A linux server I built in college 20 years ago is still running.
    The only folks who are going to accept linux as a fault are new linux users. 
    On paper the Uno Q sounds amazing.
