@maz Yep, sure have. But, I'll try again tomorrow and report back.

@stoffera So I really did brick it then?

@stoffera It's not showing up in System Profiler, nor via monomake monoprog -d.

What can I try next, please?

Thanks!

@stoffera tried both; results per my original note above. I'm guessing I need to worry.

So, I was playing around with my first app, and as happens sometimes, I messed up somewhere. My device is now non-responsive.

Ok, no problem, right? This thing's got to have a reset button somewhere. Oh, there it is! And there are the instructions on how to reset it back to the bootloader.

But, I have followed the instructions 6 or more times now, and the device is still - for all intents and purposes - dead.

I even peeled off the back of the case just to make sure I was really depressing the reset switch. No love.

Occasionally, tantalizingly, monoprog detects it as available and running an app:

Mono device running app detected.

but then I can't successfully make install:

Resetting Mono device to start bootloader
Programming Mono device with hallowelt.elf...........
Mono device not detected on USB ports.
No connection to Mono device.
make: *** [install] Error 2

Worse, after another attempted reset, monoprog goes back to not seeing the device at all.

Thoughts?

Thanks!

Now I've got a different problem, in that I appear to have bricked my device, and can't get it to respond to my reset. (With paperclip and user button.)

@pktm OK, so the trick with minicom was related to settings. Not only did I have to put it to 9600bps, I also had to turn hardware flow control off and save the settings as minicom defaults. ($ minicom -s).

I'm documenting that here to help others, and I'll add it to the serial debug article in the docs, too.

@maz Thanks for the reply.

I changed the bit rate in minicom, but I'm still not seeing any output, frustratingly.

I guess I should have posted the full switch block, but it doesn't use the rand() value directly:

    switch (newColorCase) {
        case 0:
            helloLabel.setTextColor(display::WetAsphaltColor);
            break;
//...

Thanks!

Following the examples, I added a simple timer to change the color of the text label in the Hello World starter project.

//inside AppController::AppController()
    Timer timr(1500);
    timr.setCallback<AppController>(this, &AppController::timerCallback);
    timr.Start();

which ties into:

void AppController::timerCallback()
{
    // set another text color
    int newColorCase = rand() % 6;
    printf("new color choice: %i\t\n", newColorCase);
    //...
    helloLabel.repaint();
}

But the color never changes, and minicom never sees the debug statements.

What am I missing, please?

Thanks!

@stoffera Ok, I think that fixed it! I'll do a bit more work with this today. Thanks!
