Teensy 4.0 First Beta Test

**bicycleguy** · 08-26-2019, 03:00 AM

@Paul
Trying rev 4. Using DejaVu.ino and repeatedly compiling, loading, changing ect. as before and haven't got any out of memory errors I do get:

java.lang.InterruptedException: sleep interrupted
at java.lang.Thread.sleep(Native Method)
at processing.app.inputPipeListener.run(TeensyPipeMon itor.java:234)

when I close the terminal window while it's running.

I did get this once, but I was playing with the terminal window scroll bar. I had scrolled the thumb to the window bottom and when I closed the window:

java.io.IOException: Stream closed
at java.io.BufferedInputStream.getBufIfOpen(BufferedI nputStream.java:170)
at java.io.BufferedInputStream.read(BufferedInputStre am.java:336)

at java.io.InputStreamReader.read(InputStreamReader.j ava:184)
at processing.app.inputPipeListener.run(TeensyPipeMon itor.java:229)
inputPipeListener thread exit

But the App kept running. I was never able to crash it with Dejavu.ino.

I froze the Arduino App once with millis() print program after a lot of messing around, but it didn't give an error indication (no memory error at least

)

Code:

int thisdelay=100;

void setup() {
  Serial.begin(9600);
  while(!Serial)
   ;
  Serial.print("Starting up with ");
  Serial.print(thisdelay);
  Serial.println(" delay");

}

void loop() {
  Serial.println(millis());
  delayMicroseconds(thisdelay);
}

Here's a 5th try. This one keeps the memory reduction of #4 and fixes many of the bugs. Should be good to test on Windows and Linux (eg, not a huge regression from #3). It should be noticeable more efficient on all platforms.

I also tried to speed up some parts, especially the line searching. Maybe that will free up CPU time to allow the Java GC to work better on Macintosh? Right now I'm having a hard time imagining any more ways I can improve this for Macs. Maybe more ideas will come after some sleep.

This version still has occasional "StateInvariantError: Can't render line" errors. You might see the negative number warnings too. Right now I'm not too worried about those, unless they cause the output to stop or do something very wrong. If you see StateInvariantError but nothing noticeably wrong with the output, please just ignore it for now.

If you see *other* errors, especially any errors mentioning "inputPipeListener" and "TeensyPipeMonitor" or any out of memory exceptions, or freezing the output or Arduino completely locking up, or just running unusably slow, I really want to hear about those!

**defragster** · 08-26-2019, 04:49 AM

5th_Try Seems to be working well.

Might have stepped up from 235K toward 250K lps on my 6 per line lps.ino.

I saw two of the : 'javax.swing.text.StateInvariantError' but no new errors. And those often hit the first time after Upload.

Done a few uploads and resizing and nothing triggers yet.

Did board to T_3.6 and back and no issue.

Oddly [not] it messes with Win Remote Desktop - had to come to the machine …

Will let it run and interrupt it again later -

<UPDATE>: Sitting most of 2 hours - 154 instances of the error ".StateInvariantError: Can't render line"

Still functional and stable - switched to other T4 and upload and Button and Upload in combo keep working the IDE RAM and CPU% seem to be in order.

@Paul

Had to mess around quit a while opening and closing monitor window, recompiling, loading with terminal in various states until finally after pressing show timestamp and closed the window when it wouldn't the first error message :

inputPipeListener exception: java.io.IOException: Stream closed
java.io.IOException: Stream closed

at processing.app.inputPipeListener.run(TeensyPipeMon itor.java:236)
inputPipeListener thread exit

Then after maybe 4 more times of recompile, load overflow, I tried to open the terminal window got:

And after waiting a minute or so and trying terminal window again:

java.lang.OutOfMemoryError: GC overhead limit exceeded

At this point I had to kill it.

However, it was really impressive what it took to freeze it. I don't think any normal use would ever do what I was doing to it. Way back at try 1 or 2 normal stupid programming could have caused the problems, but now you have to make a concerted effort to try and mess it up.

I still want to try the milliseconds printing code but the wife beckons...

**defragster** · 08-26-2019, 07:19 AM

One thing I see is the scroll to place new lines seems to vary by about a pixel - looking at text it doesn't jump in place or draw clean and fresh -

But seems to jitter up and down 1 or 2 pixels.

Updated last post with no new errors - but 154 of the old ones in past 2 hours.

<edit>: It doesn't do it on short lines like this : 23135 @ 23135643

But it does on longer lines like this:

count=11262499, lines/sec=251487count=11262500, lines/sec=251487count=11262501, lines/sec=251487count=11262502, lines/sec=251487count=11262503, lines/sec=251487count=11262504, lines/sec=251487

New Note:
Just made IDE hang - been running and occasional upload to flush the repeat errors off.

It was running in T_SerMon and I clicked as the text scrolled it blue selected a few lines and HUNG - No console Error notes were added - three open sketch windows in one instance and the sermon window - had to TaskMan: End Task.

Restarted IDE - it does not do it now. Selecting grabs some and flashes and continues. Odd though it selects from bottom up to mouse pointer - not a point scrolling up from mouse. Must have been accumulated 'damage' from prior errors.

Noticed that 'add timestamps' not working?

Did you get any OutOfMemoryError messages, like Heap or GC problems?

I believe the lockups and errors like StateInvariant, BadLocationException, and negative number warnings are probably a multithreading issue. Maybe this?

https://www.javamex.com/tutorials/th...okelater.shtml

I'm going to make a 6th try soon, once I figure out how to use SwingUtilities.invokeLater() and have the input listener not clobber the data before "invokeLater" happens....

But on the memory use and the GC issues on Macintosh, pretty sure that won't make any difference. My best guess is the remaining memory use, spewing more onto heap than the garbage collector can clean up, might be coming from InputStreamReader. Maybe? Even if it is, not sure what I can do about that.

**PaulStoffregen** · 08-26-2019, 03:46 PM

Here's a 6th try. This one moves updating the FIFO onto the GUI event thread. Hopefully this will solve the StateInvariant, BadLocation, negative numbers and mysterious lockups.

I suspect there's still a bug or two involving selecting text. So if you get these sorts of errors, please let me know if they happen when you click in the serial monitor window, or if you were resizing or dragging the window, or if they just happen spontaneously.

Also please keep an eye out for "ERROR: GUI update failed". If you're capturing stdout on Linux or running the Arduino debug version of on Windows, that's normal when you quit Arduino. It's not supposed to happen any other time.

If you see the "*****NEGATIVE NUMBER ERROR*****" message, does it have a Java exception, or just an annoying warning without any sign of actual error?

As always, I want to know how the memory usage is looking, especially on Macs. This should be similar to #5. Performance might be a slightly slower, maybe?

Yes, I forgot to mention. I did a quick test before the 3 mentioned above and before my morning coffee. I got those message only the first time I opened arduino after replacing pde.jar.

Tried #6 on MAC again...

Again simple app, simply output one line of text with loop counter, as fast as it will run

Ran maybe a minute and stopped output.
Closed window, opened again, ran maybe 3-4 minutes before hang.
closed and opened another couple of times, Did not wait for hang.
On the 5th or 6th open attempt. got the error:

@Paul: -- still 6th Try JAR in place on Win 10
Left my machine - I thought running T4 code above to t_sermon - came back and it was stalled - no 'error' text in the console.

Now I do IDE Upload w/TLoader and it runs only a few seconds and stalls:

Code:

 >count=10422469, lines/sec=240429 >count=10422470, lines/sec=240429 >count=10422471, lines/sec=240429 >count=10422472, lines/sec=240429

That shows only 422K counted prints from start - then it just stops.
> Nothing untoward in JAVA for RAM @ 542MB and running CPU% from 0.5 up toward 2%
> No longer dropping the noted p#4213 error in console before compile starts
> Restarts each time on Upload for a short time
> Closing t_sermon and then restarting from IDE repeats this where it will pick up and run a short time - stalling with no error
>> No Error or Orange text generated in the Console window when it stops as before.

At this point I did the t_sermon close and restart 2-3 times and then I got this in the IDE Console:

Code:

// NOTHING but build details up here

I hadn't tried that - was wondering if it was on MAC or Win. But took my Running T4 to Bootloader with TLoader closed.

Closed and opened Sermon about 4-5 more times and got this:

Code:

@neurofun - Interesting left T4 in bootloader and restarted IDE and on the sixth open of T_sermon I got this again just now on Windows 10:

Code:

...

And IDE can do Compile and Upload but it will not open T-sermon - always errors:

Paul - char prints and line breaks getting mixed up - see the end of this post :: USB-Mass-Storage-Driver-Experiments

<EDIT> : WORKING CODE BELOW SHOWS THE ISSUE
> Note Try #3 WORKS properly :: Teensy-4-0-First-Beta-Test #4171
> Note Try #5 shows the same Breakage :: Teensy-4-0-First-Beta-Test

Looking at text from Copy&Paste there the dots are in a row on same line - but screen shot shows like this as seen:

Click image for larger version.

Name: Try6_BadnLine.png
Views: 4
Size: 11.8 KB
ID: 17332

That is with the Try #6 Java on Win IDE 1.8.9 TD 1.47 and the latest libs to make the USB Host sample work - so not something you can test unless you want to go grab all that.

I'll try to set up a DEMO sketch of just similar DOT prints …

NOTE: IDE was opened Fresh. Did some dozen uploads for that post and otherwise the try#6 with typical status prints this is the only oddity I saw - no other Console Errors.

Working on Demo - just got this:

Code:

ERROR: GUI update failed
java.lang.InterruptedException
	at java.lang.Object.wait(Native Method)
	at java.lang.Object.wait(Object.java:502)

	at processing.app.inputPipeListener.update_gui(TeensyPipeMonitor.java:281)
	at processing.app.inputPipeListener.run(TeensyPipeMonitor.java:251)

DEMO going oddly - what is printing isn't as expected - opened TyCommander for second Sermon view - that came up on closing TyComm and then opening t_sermon IIRC.

Note IDE been open for as noted some dozen uploads - though no abusive SPEED runs until this.

Here is loop for WIP code - I think it shows the issue:

Code:

void setup() {
  while (!Serial)    ;
  Serial.print("Starting up ... ");
}

uint32_t count = 0;
void loop() {
  delayMicroseconds( 200 );
  count++;
  if (!(count % 10)) Serial.printf(".");  // SAME WITH :: Serial.print(".");
  if ( !(count % 400) ) Serial.println("<nl>");
}

Cut and paste gives:

Code:

Starting up ... ........................................<nl>
........................................<nl>
........................................<nl>
......................................

But screen shot of same shows:

Click image for larger version.

Name: Try6_BadnLine_B.png
Views: 3
Size: 11.1 KB
ID: 17333

And expected output as shown from TyComm - where there is one space in starting up line:

Code:

Starting up ... ........................................<nl>
........................................<nl>
........................................<nl>
........................................<nl>
........................................<nl>
........................................<nl>

So the extra NewLines are artifacts in GUI drawing of t_sermon

**defragster** · 08-27-2019, 10:13 PM

@Paul - Relating to post #4220 did a more exciting update showing working and non working behavior with a bit of flair showing counts and cycling between one and the other:

Code:

void setup() {
  while (!Serial)    ;
  Serial.println("Starting up ... <nl>");
  for ( int ii = 2; ii < 12; ii++ ) {
    for ( int jj = 0; jj < ii; jj++ ) Serial.print(".");
    Serial.println("<nl>");
  }
  for ( int ii = 2; ii < 12; ii++ ) {
    for ( int jj = 0; jj < ii; jj++ ) {
      delayMicroseconds( 200 );
      Serial.print(".");
    }
    delayMicroseconds( 200 );
    Serial.println("<nl>");
  }
  delay ( 3000 );
}

uint32_t count = 0;
elapsedMillis emTick = 0;
void loop() {
  if (emTick < 6000)
    delayMicroseconds( 200 );
  if (emTick > 8000) {
    emTick = 0;
    count = 0;
  }

  count++;
  //  if (!(count % 10)) Serial.printf(".");
  if (!(count % 10)) Serial.print(".");
  if ( !(count % 400) ) Serial.printf("%lu<nl>\n", count);
}

And funny enough in compiling/uploading this a FEW times the Console just barfed out this - I may have clicked 'OFF Autoscroll' at the time:

Sorry I've been absent the last ~24 hours. The biz size of PJRC pulled me away from coding, as it does at times. The upside is we got the 3rd batch of Teensy 4.0 boards into production 1 week early, and got sort-of caught up on a big backlog of pending orders. I'm looking at this stuff again now, and I should be back on it late tonight. Hope to have a 7th test by the morning.

First up, I'm going to work on the "GUI update failed" InterruptedException error. I know how to fix that one, or at least I think I know what to do. Everyone here can be the judge of whether I actually manage to fix it.

On repeated opening of the serial monitor using up all the memory on Macintosh... I'm less certain of what to do. Currently the JTextArea is created with the default document object (GapContent-based) and we create an instance of FifoDocument to replace it. My understanding is Java GC is supposed to clean up that original one. But maybe it's not doing that on Macintosh? Honestly, I'm pretty frustrated with Mac. Going to try to grab an older mac with 10.12 installed. My Macbook Air just doesn't reproduce these out of memory errors.

Great to get a week jump on the bigger batch.

Hopefully prior posts where try#5/6 show odd GUI draw versus try#3 make sense - and the other issues clear up MAC and WIN.

The yield() calls on the Teensy 4.0's super fast loop() take a big toll. Putting a while(1) inside loop around the code in #4221 show a HUGE difference for not leaving:

Code:

  // In while(1) no loop/yield >> t_sermon :: 17,257,242 and TyComm :: 17,257,045
  // No while with loop/yield >> t_sermon :: 5,233,315 and TyComm :: 5,233,326

In closing SerMon after numerous uploads - then opening TyComm to see before disconnecting and then going back to t_sermon This fail to Start t_sermon gave this on Win 10:

For fun I asked for EMAIL on restock at AdaF and SFun - just got email from SparkFun:

There are now 1 units of the Teensy 4.0 (DEV-15583) immediately available for purchase from SparkFun Electronics.

And going to website the item shows that ' 1 items in stock' there too. - that lasted all of 5+ minutes … but they may have filled their existing backorders.

AdaFruit still 'Out'.

**mjs513** · 08-28-2019, 06:13 PM

Just out of curiosity just checked Adafruit and its still showing OUT OF STOCK. Either I missed it or they sold out really fast
