Teensy 4.0 First Beta Test

**defragster** · 08-22-2019, 05:57 AM

Paul - Very good update for Windows - just some more fun with the rest of the UI tidbits.

~6.5 Hours running here - first and one follow up upload of the LPS.ino. That is twice closing the t_sermon as noted in prior post.

At this point still running happily - just got back to looking it was up at 230K … now 210K … then back up to 230K.

It is clearly faster and IIRC the old version would have croaked long ago.

That was a long term little disturbance run - just cut power ~10 times and t_sermon picks up on repower.

… a couple other interruptions and uploads pending …

>> Did half dozen power Off>On' and t-sermon picks up running fine.
>> did 10 Button to bootloader and TyComm sending Reset and it did and came up running fine
>> did 10 Button to bootloader and TyComm Upload of prior lps.hex and it did and came up running fine
>> did half dozen USB cable Pull and Plug and it came up running fine.

That seems MORE robust - I've had times where I had to Close SerMon window and click open again to get it to establish a connect.

>> THIS got dropped on the wrong thread … blaming the foum software since it was too big it failed to post a few times …

Paul: loop() Code Mod to lps.ino - for a bit more stress that breaks here:

Code:

void loop() {
  while (1) {
    Serial.print("count=");
    Serial.print(count);
    Serial.print(", lines/sec=");
    Serial.println(count_per_second);
    count = count + 1;
    uint32_t msec = millis();
    if (msec - prior_msec > 1000) {
      delay(1);
      // when 1 second as elapsed, update the lines/sec count
      prior_msec = prior_msec + 1000;
      count_per_second = count - prior_count;
      prior_count = count;
    }
  }
}

With or without the delay(1); on the second update this ruins the operation of Teensy_serialmon. It dies if running - won't get past the first second or now won't start at all.

At the same time TyCommander for Serial monitor is running at 74K to 116K lps. And running well for some minutes. IT IS USING 29.3% CPU - making this fitful to type. Which is the typical unchanged performance I've seen - until something worse happens where it gets longer faster strings.

IDE has this in the console: TOO LONG at 270K chars … see file - that had to be zipped for 80KB over limit ::

@Paul, @mjs513, @defragster - Not sure which thread to mention this again:
UncanneyEys0 (earlier mjs513 version) -

Thought I would try loading it again. And it built fine:

I am used to having this one kill the USB... But this time when the load completed, windows 10 64 bit gave me a message about installing new device (NXP Generic device???)...

out of Curiosity, I wondered what it would do if I plugged it into a linux board. Most convenient one I had was RPI4, So I plugged it in there, and sure enough it is showing up as some generic device?

Taking a look at the system messages I see:

Again not sure if any of this information will be useful, but grabbed it while I could

@Paul, @mjs513, @defragster

I just gave it a try to see if I could duplicate it and I was sort of able to, to a degree.

I caused uncannyeyes to fail in my usual way, with one of the eyes without progmem. I do still loose USB but I don't get the window error about loosing the usb port. It prints the setup info to sermon if I open it right away but I will loose the port in the IDE (it gets grayed out). I can upload, but had to do a 15s restart once. I was trying different things - tested it with and with the imxrt-size receipe in the platforms.txt file just out of curiosity.

UncannyEyes is getting stranger and stranger.

**defragster** · 08-23-2019, 12:55 AM

I recognize those 'found devices' - and posted … not reading for context just now - but here are the links matching by name for ref::

**defragster** · 08-23-2019, 01:01 AM

Popped back to the duplicate post above that listed both names

@KurtE and @mjs513 :: Are you both using Production boards? In scanning those, that was in the white wire timeframe - not that I know why that would be an issue …

**KurtE** · 08-23-2019, 02:25 AM

The last one I reported was using one of the white wire versions of the T4...

I am pretty sure the: 16c0:0486 Van Ooijen Technische Informatica Teensyduino RawHID
Is a normal value for Teensy...
Likewise for: 16c0:0483 Van Ooijen Technische Informatica Teensyduino Serial

My guess is that the 16c0:xxxx was originally purchased by Van Ooijen Technische Informatica, who then resold a range of them to PJRC...

And for example if you look at usb_desc.h, you will see information like:

Code:

Quick follow up on this from #4152 with the while(1) in the lps.ino loop() - Closed IDE and got back to this on teensy_sermon and it has been running fine some time at the same range of rates as before. So it was some accumulation hopefully the failure path is in the console log.

@Paul - Terminal Monitor Wish list...

Sometimes when I lose USB (either because I unplug it, or something in program kills it), I wish I could still select and copy the text to the clipboard so I could post it, or put in into edit buffer to diagnose things.

For example "THE **** program killed USB" and I have some debug information like:

Name: TerminalMonitor.jpg
Views: 7
Size: 69.4 KB
ID: 17289

In this case, I had added some debug code, that compared the actual memory that startup.c copied and zeroed, to the current values, at the start of setup(). I expect some of the differences.
D!=S - was areas that we copied. D!=0 was areas we zeroed...
The first copy of D!=S values are: F_BUS_ACTUAL, F_CPU_ACTUAL, usb_string_serial_number

The others in this area are values in the range:
20028a30 d impure_data
20028e58 D _impure_ptr

I have not gone through the areas that were cleared, as probably not as interesting. But maybe interesting is where USB died...

Click image for larger version.

So maybe again maybe it will boil back down to some problem in the st7735_t3 library which again is showing up when the code does: mytft = new ST7735_t3(...)
And as such the object is created in the HEAP...

But again back to point of this message. Wish I could have simply copied the above text...

**KurtE** · 08-23-2019, 06:32 PM

@Paul, @mjs513, @defragster - Maybe found what was trashing memory

(At least in the above case).

One of the two constructors for st7735_t3 was not initializing a few key variables (which should be nullptr or 0...) Did not show up in all of the cases where someone did something like:
ST7735_t3 tft = ST7735_t3(...);

As this was allocated in DTCM and either init or zeroed. But in this case the code does: new ST7735_t3(....) which allocates the data up in OCRAM and it is not init and maybe garbage...

I added some more init code up in the branch: https://github.com/KurtE/ST7735_t3/tree/T4_DMA_LOW

You might try it to see if it fixes your version of crashing in UnCannyEyes!

**defragster** · 08-24-2019, 12:54 AM

Good work KurtE - now I know why I always thought user code was to init everything - even if zero.

And TRUE point about the IDE SerMon going dead when 'offline'. One reason I tend to use TyCommander. It doesn't block Copy or scroll back - and also doesn't wipe between restarts (selectable)

@Paul: Would also be nice to be able to start multiple instances of teensy_sermon - especially being able to run outside of IDE if possible. Is there a CMD_LINE startup for the EXE? Puzzling the "FirstTry" update was just a JAVA.JAR change and no update to the EXE when IIRC the t_sermon was not a JAVA app?

AND UPDATE to p# 4152 / #4158 on update to teensy_sermon:: That sketch is STILL running now 21 hours later without issue using the while(1) and never leaving loop(). So as anoter @user prior post noted - it may involve restart/upload cycles for instability - not just pure exec speed.

The console output in IDE is still very short from uninterrupted execution - unlike the FAULTING log posted in #4152 that needed to be zipped:

Here's my second attempt at speeding up the Arduino Serial Monitor. This one should (hopefully) have everything working....

Like the first (msg #4139), to install this find pde.jar inside Arduino and replace it the copy from this ZIP file. Make a backup copy of the original pde.jar outside the Arduino folder, in case you want to restore Arduino to the way it was.

This version should make AutoScroll work properly. You should be able to select and copy text. I even tried to make the text accessible after USB disconnects. Hopefully there are no more Java exceptions or error messages?

Java memory usage is expected to slowly creep upward and then make sudden drops. That's the normal process of Java garbage collection. The big question is whether this runs acceptably on your computer. Is it free of hangs or pauses (like when that garbage collection happens)? Does it run fast & smoothly? Does it affect the speed of other programs (no Arduino) running on your computer?

Please give this one a try and let me know how it works for you?

RE: serialmon_speedup_2nd_try.zip

Seems to work - same speed as 1st. Stopping AutoScroll to copy text or page - stops incoming data write/update? Scroll bar surges a bit - as if it is filling a buffer then freezing that buffer and starting a new one - then it rejoins/jumps with autoscroll enabled. Which seems usable to capture - if done at the right time!

Indeed Button push on T4 and t_sermon allows select/copy of text from text area:

Code:

count=50444750, lines/sec=216682
count=50444751, lines/sec=216682
count=50444752, lines/sec=216682
count=50444753, lines/sec=216682
count=50444754, lines/sec=216682
count=50444755, lines/sec=216682

And POWER Off>On restarts in same window without reconnect.

I found some Console notes here on Win 10 after playing with Clear/AutoScroll/Scroll bar:

Thanks, so far so good. And as @defragster mentioned, it looks like, I can select and copy and paste:

Code:

Estimated max stack usage: 1640
36
Estimated max stack usage: 1640

even if I disconnect from USB, which is a great help!

Yes, if the buffer completely fills. This is different behavior than Arduino has today, which I consider to be a bug, though I will admit it's sort of a matter of personal preference.

With stock Arduino 1.8.9, if you turn off AutoScroll and a lot more data keeps arriving, eventually it will scroll or blank your screen. If the data is coming in at Teensy 4.0 max speed, "eventually" is a matter of seconds. I don't like that. If you've turned off AutoScroll, the window should not scroll or move on its own. At least that's my opinion.

But what should the serial monitor do is the buffer completely fills while you have AutoScroll turned off? What I have in the code now is the serial monitor tries to keep 40% of the buffer free while scrolling, so you can still receive quite a lot more data after turning off AutoScroll. But the buffer doesn't grow. When it completely fills up, if AutoScroll is off then it must discard the imcoming data. Deleting anything from the buffer can cause the window to scroll or jump or blank while you're reading.

If the buffer fills and you turn AutoScroll back on, the first incoming character causes ~40% of the old data to be immediately discarded. Scrolling mode uses 60% of the buffer, in anticipation that you might turn off AutoScroll at any moment.

I found some Console notes here on Win 10 after playing with Clear/AutoScroll/Scroll bar:

Looks like I *still* have more work to do! Anything you can give me to reproduce this here would really help. Or maybe I'll have to make a 3rd version that prints quite a bit more info about what led up to that problem.

**defragster** · 08-24-2019, 05:39 PM

Machine a bit WONKY - tried to post and EDGE failed I see - then I see new posts … here is what I saved … hit BUTTON on T4 to pause running - have not looked at PERF number in TaskMan - will restart and do that:

I see it added a couple of new CONSOLE notes since first post - but still running and ZERO signs of corrupted lines or lost data

The Errors seem to show on restart? Hit Button { using TyComm so no AUTO load } - then unplug/replug and a new set of CONSOLE text appears.

Indeed the AutoScroll behavior seems good and usable - it will be like shooting fish in a river trying to hit fast moving 480 Mbps spew ... but that is life. At least it stays where stopped for review and edit - and as noted - continues to fill current 'buffer space'.

I closed IDE and restarted and notes above seem correct for repro - it is on restart after bootloader?

TaskMan happy - everything CLOSED with IDE and after restart I see this that looks good - though stopping Teensy allowed me to better post the above last time.
As note before TyComm has half the throughput at 30% CPU and teensy_serialmon && JAVA are shoing under 10%:

@Paul: closing TyComm and IDE then IDE restart {no T_loader} and open t_sermon it picks up running. Did POWER OFF then POWER ON and got the error on second Power cycle to ON - with vBat removed - No Button:

<EDIT>:: About an hour later without interruption and still running perfectly well with no signs of data loss/corruption in display - an no new Console Errors. So indeed it is the 'Stop/Start' of T4 exit/arrive that causes the errors it seems - which is where trouble comes with repeated uploads.

Currently SIX sets of lps.ino update per line that would show it , and dropping those 5 \n's has the Win 10 throughput at +/- 230K lines per sec.

**defragster** · 08-24-2019, 06:58 PM

@Paul - just seeing pjrc.com

Inventory Status: Out Of Stock
Last physical count: Aug 23, 2019
Update, Aug 9: More Teensy 4.0 are in production now

Congratulations again

- but it might be good freshen "Update, Aug 9" with the incoming BIGGEST EVER Batch #3 expectations for September - and the good news that second batches have gone out to other distributors.

Speaking of feature creep and helpful suggestions:
> can the t_SerMon be changed for on the fly font size change with CTRL and [+/-] or Ctrl+Mouse Wheel?
> Multi Instance of t_Sermon to UART debug or second active Teensy

**bicycleguy** · 08-24-2019, 08:32 PM

@Paul
Tested your second try and really like it as others have commented. You asked for issues so: Can still crash Arduino where memory is ~780MB CPU 350%.

Here's a little more precisely how to do it.
1. Compiled and loaded DejaVu with Serial.println("DejaVu"); commented for known start state, opened Arduino serial to verify.

DejaVu.ino

Code:

void setup() {
  Serial.begin(9600);
  while(!Serial)
   ;
  Serial.println("I'm starting up");
}

void loop() {
  Serial.println("DejaVu"); // comment and uncomment this line
}

2. Quit Arduino and Teensyduino but leave T4 plugged in.
3. Start Arduino, deny network connections, and open seral monitor as below.(the other serial method works fine ie slower)

4. Leaving monitor open and with Serial.println("DejaVu"); uncommented hit upload button.
5. Close monitor window after about 2 seconds of DejaVu.
6. Comment println and upload. Open monitor, all is good.
7. goto 4.

Usually seizes after 2-4 tries, not sure about effect of length monitor is open and exact effect of messing with auto scroll button, can crash either way.

As far as usability, this version seems 4/5 stars for me. The procedure above would take a real twit to not fix the problem first. The only reason not 5 stars is because I'm a real twit

Here's a 3rd attempt. This one adds synchronized functions, to check if these negative number errors are due to multi-threading conflicts.

Other than the question of whether this solves those bugs, the big question is how much this hurts performance? It's likely to increase CPU usage. Memory use should be pretty similar.

**el_supremo** · 08-24-2019, 10:54 PM

I've tried the 2nd attempt on Windows 10 Pro x64 on a 6 cpu (12 hyperthreads) i7-6800K @3.4GHz and 64GB of ram with arduino 1.8.9 + TD1.47
If I just leave it running, the Java process uses about 5% of the cpu and reports about 175,000 lines/sec.
However, if I try disconnecting and reconnecting the USB or just hitting the reprogram button, it generates the Negative number error exactly as reported by @bicycleguy and @defragster.
I think I can make it happen consistently. If I hold the button, or remove the USB plug for 5 seconds or less and then reconnect, it will continue without any error. But if I wait 6 seconds or more it throws the Java error. It usually only throws the error once and recovers. But one time I tried it, it just went into a loop throwing the error continuously.
I get this repeated:

It occasionally throws an extra error line in there too:

Has anyone tried the 3rd attempt (msg #4171) on Windows?

My best guess so far is the "StateInvariantError" may be a thread synchronization bug. The 3rd try attempts to fix that by synchronizing all the functions. If that works, the question is what does it cost in performance. On Linux, seems about the same.

Just tried the 3rd attempt. Looks like a winner. Even if I pull the plug or hold the button for 20 seconds, it still recovers without an error message.
Speed seems to be the same - varies from approx. 169,000 to 176,000 lines/sec - and cpu usage looks essentially the same.

I am currently using for I guess you would call normal operations - the only thing I noticed is the SerMon is gray when data is getting dumped to it and white when I am doing a compile/upload until data starts streaming then it turns gray again. Haven't done any heavy dumps yet.
