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.

  • 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??
