Anyone Have stability issues with Arduino Uno Q?

SensoredHacker0

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.

    A bit aside, but I see the Opta in the same category of "not ready for prime time".  I have one.  It's too quirky.  It's not what I consider "Arduino" - which, to me, infers stable and well supported (both by the company and the community).

    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.

    When ever Opta first came out, my employer wanted desperately to switch. but all the devices you might want to interface with were locked out. I wrote to Arduino and they said they were concerned about licensing, which amounted to a locked down open platform. as I understand it, that has improved over time, but still, we couldn't adopt it. if anyone is going to transition, to some other system, that system either needs support for other devices, or needs to have devices that offer the missing functionality.  Arduino Opta had neither. 

  • Welp, I re-flashed the linux image, but the arduino bits are still doing the same thing. it says the code uploaded but doesnt run it.
     so then IDK i messed with it ALOT.

    My conclusion:
    The Uno Q, despite appearing to be functional in the traditional arduino toolchain is not actually, compatible with it, and subject to breaking if you try to to use it the same way.
     
    Saying it another way, The integration of Arduino Uno Q is not complete. the code examples for everything are not going to work right, and the IDE is not going to tell you.

    so then I got on the shell. and wrote code from there, it worked, but, no serial.

    so then more digging:
    you can to this to build and compile in the same step, which was a function of the build command prior to Arduino's acquisition.
    Evidently, just pressing build doesn't save and compile you code as it once did. 
    $ arduino-cli compile --upload -p /dev/ttyACM0 --fqbn arduino:zephyr:unoq .

    Here is a corrected blink.ino for the Uno Q.

    #include <Arduino_RouterBridge.h>

    void setup() {
      Bridge.begin();
      Monitor.begin();
      pinMode(LED_BUILTIN, OUTPUT);
      Monitor.println("BOOT");
    }

    void loop() {
      Monitor.println("Off");
      digitalWrite(LED_BUILTIN, HIGH);
      delay(400);

      Monitor.println("On");
      digitalWrite(LED_BUILTIN, LOW);
      delay(400);
    }

    "Note: Serial still works over UART"

    I'd say thats a lie, but it was working for the first few days, which is very confusing. 
    Its like someone came in an broke all the macros. I can write my own, now that I have a better idea why they are broken. 
    I just wish we werent pretending they we're broken. would have saved me several hours, and much frustration.
    For real, why would we mess with the serial library??? you know how much stuff that breaks??

  • From your problem description, I can just imagine that it is just typical Arduino thing. Most people have experienced this..

  • in reply to embeddedguy

    Weird, because for everyone I know IRL, these things typically just work.

  • This video (from 8 mins) might help explain what's going on... suspect your issues are related to this new "LLEXT" feature
