Teensy 4.1 Beta Test

The AUTO init of PSRAM has some value - but indeed some issues if those pins are in other use - and it isn't needed for Teensy startup to get to setup().
and current code doesn't get a warm fuzzy confirmation the PSRAM is the right one yet:
Code:
ERAM ID: 0D FD DF FF FF FF FF FF
at 0x 7000000
Wrong ID  :-(

To use current lib for above SD test takes just this simple code when user adds PSRAM:
Code:
#include <extRAM_t4.h>
extRAM_t4 eRAM;
uint8_t config = INIT_PSRAM_ONLY;
// …
void setup() {
	eRAM.begin(config);

Funny thing I moved this SD sketch before PSRAM to T_4.0 { the FRDM 4236 board that looks about the same } to test for another thread.
Then adding above CODE to get eRAM - I compiled a couple of times wondering why it wasn't working and what else I needed … then it worked when I switch to T_4.1

Having eram_malloc() would be a better add. Because this is confusing and UGLY getting the numbers right:
Code:
struct datrec *dbuff0 = (datrec *)0x70050000;
struct datrec *dbuff1 = (datrec *)0x70090000;
 
I hear you, and would agree if they were actually shipped with chips installed.

And we don't currently initialize other hardware, like SD cards or ... So just sort of wondering. The options I currently see for this include:
a) Automatic - More foolproof (maybe) - For RAM I understand for Flash, do you assume that the it will be used as a drive or do you expect that some other user init code will be called?

b) Keep it sort of like today, where maybe the user has to call some method to initialize external memory. We could keep it as external library or bring into core. Nice thing about this is you are flexible and your sketch only takes a code size init time hit if your program actually says it wants to use it.

c) Fault handling? - If the user sketch tries to use the external ram and has not called the init function, could we detect this in fault handler and do it for them...


I think this could be another nice application for adding "-I{build.path}/sketch" to plattform.txt (see here https://forum.pjrc.com/threads/6074...Arduino-sketch?p=238051&viewfull=1#post238051). The core could then read an optional config file from the sketch folder, in which such and other configuration stuff could be defined conveniently and in project scope.

Or the more general defs.h solution which allows even more ;)

Luni, both will not happen.
Me and a few others are suggesting these things since years - without any reaction from Paul. Not even a "No, because...<insert reason here>".

:)

I hope new versions will - at least - not overwrite my changes in the future.
But I don't see much chance for that either. Not worth to write lenghty posts about it. I gave that up.

Don't let yourself get frustrated, at the end of the day this is all just fun. :)

Anyway, where can I read about your 'def.h' thing?

Sadly, since packaging up 1.52-beta4, nearly every available hour this week has been prepping to release the product (soon-ish). Haven't had time to do any software stuff since beta4.

Planning to add the PSRAM auto-init and fix audio ADC on Teensy 3 (dunno how that slipped in... I tested it many times on both boards) on Saturday. Might get to the malloc thing, might not. I still have a long list of urgent things to complete before we can release the product.
If we have a generic heap alloc, where we pass in which heap or like ESP32 where you pass in attributes desired, we could have 3 heaps, ram, dmamem,extmem... and potentially only init one of these like extmem, if user asks for it... just a thought

Or a more clever one which uses all three automagically..
Nice Idea, Kurt.
 
Using the Teensy 4.1, I just tested quad audio out using the two Teensy Audio Shields. Success!

Interestingly, I was not able to get it to work using flying leads. I had to stack the boards (cutting the traces and whatnot, as required) in order for this to work. I was able to use flying leads for T3.6 and T4.0. I don't know why it wouldn't work with T4.1. User error is the best explanation, but unsatisfying.

So far, I've only tested the audio output, not input. Still, it's nice to see that the quad works.

Here are the mods required for the second audio shield:

* Cut the trace between the two pads for the audio board's RX (Pin 7)
* Cut the tracce between the two pads for the audio board's TX (Pin 8)
* Add a wire from pin 6 over to the pad that had been connected to pin 8
* Add a wire from pin 32 to the pad that had been connected to pin 7
* Cut the trace between the 3 pads that set the audio sheild's address (was LOW)
* Solder-bridge the center pad to the other pad (sets the address to HIGH)

Here is the ToneSweep code that made audio on all four output channels:

Code:
/*
  Demo of the audio sweep function.
  The user specifies the amplitude,
  start and end frequencies (which can sweep up or down)
  and the length of time of the sweep.
   
  May 2020: Chip Audette (OpenAudio)
    * I tested this with the Teensy 4.1 and two Teensy Audio Shields
    * One shield was unmodified
    * The second shield was modified
      * Cut the trace between the two pads for the audio board's RX (Pin 7) 
      * Cut the tracce between the two pads for the audio board's TX (Pin 8)
      * Add a wire from pin 6 over to the pad that had been connected to pin 8
      * Add a wire from pin 32 to the pad that had been connected to pin 7
      * Cut the trace between the 3 pads that set the audio sheild's address (was LOW)
      * Solder-bridge the center pad to the other pad (sets the address to HIGH)

    * I based this sketch on the standard ToneSweep example
    * I extended for quad audio
    * This only tests the audio output

FYI, the USB connector on the T4.1 is intermittent when using a sparkfun logo'd USB cable. If you wiggle the cable or if you wiggle the stack of Teensy boards (as happens when you need to plug in some headphones), the system loses power. Jiggle it some more and it comes back on. I'm not saying that it's the T4.1; it could be the cable. But, this cable does seem to work OK with my other Teensy devices.

Next, I'll test the audio inputs. I have to attach some cables, first.

@Kurt- @Frank: I like the idea of Tri Heap alloc - would be nice to have the ability to declare where it is.

  Simple SD card timing datalogger for Teensy 3.6

  https://forum.pjrc.com/threads/60754-Teensy-3-6-SD-Card-missing-time-in-milliseconds?p=238352&viewfull=1#post238352

  This example shows how to log timing data to an SD card using the SD library
  and SDFat 2.0b
  As much as possible, the code uses the simplest Arduino functions, adding
  teensy-specific code only where necessary (such as IntervalTimer).

  The circuit:

   SD card attached to built-in SD Card slot on t3.6


  This example uses  buffering and interval timer to collect at regular
  intervals without collection timing jitter caused by SDC writes.
  A time stamp is saved with each record.

  A minimal user interface is added with three one-letter commands:
      'r'   Open file and start recording data with verbose output
      'g'   Open file and start recording data with only block write delay output
      'q'   Quit logging data and close file
      'p'   Play back data in CSV format


  NOTES:
    1. Unlike the Simple Logger, this version saves only the binary data.
       Conversion to strings is done on playback.
    2. Playback is done one record at a time.  This is less efficient,
       but output is going to the Serial port, so speed isn't as much
       of an issue.
    3. if you uncomment #define USE_EXFAT the program will use the EXFat
       file system of SDFat 2.0beta.  You will need an SD Card formatted
       for the EXFat file system.  That can be done with the tools
       in the SDFat examples

Alright I just pushed an update to my FNET fork, there is a new example already setup to use with FBENCH to do speed tests.

This is my average speed for large TCP transfers and seems to be the max: View attachment 19984
Keep in mind this speed test doesn't account for the overhead of TCP packets so it likely is reaching the 100Mb speeds it should be.

I added some FNET TCP/UDP performance numbers for T41 native ethernet to table in post #108
 
I threw together a wrapper library to bridge the gap between FNET and Ethernet.h.
https://github.com/vjmuzik/NativeEthernet
And a small update to my FNET fork to remove conflicts
https://github.com/vjmuzik/FNET

I've done as much testing as I could using the normal examples and some of my own sketches, so far they all appear to work as intended with no changes except for sketches that make direct calls to w5100.h. This instance of FNET is not multithreaded like my other examples have been, so this uses one IntervalTimer to poll the stack every 1ms in the background. Also in an effort to make sure this compiles from a fresh install I made a portable Teensyduino instance, installed libraries straight from GitHub, and tested it so I can confirm that it should compile without issues.

Because I tried to maintain compatibility with the standard Ethernet library some impact to the performance may have taken place.
 
@ vjmuzik:: I just got both updates to sketchbook libraries. Using IDE 1.8.12 and TD 1.52 B4

Same issues seen before? What's missing here?

Well that is a puzzle then :( This is what I noted after your last update too so I couldn't test again - and wanted to try to see the NATIVE and USBHost working from the same code.
 
@ vjmuzik:: I just got both updates to sketchbook libraries. Using IDE 1.8.12 and TD 1.52 B4

Same issues seen before? What's missing here?

Just downloaded latest version of FNET and NativeEthernet libs.

Compiled FNET_Native_Ethernet.ino without errors. However ASIXEthernet_Test.ino is giving me errors but different ones that @defragster noted:

Note this is using a T4.1 with both a Flash and PSRAM chip.

Also did a compile on the BarometricPressureWebServer.ino sketch with no errors, a few warnings though.
 
I threw together a wrapper library to bridge the gap between FNET and Ethernet.h.
https://github.com/vjmuzik/NativeEthernet
And a small update to my FNET fork to remove conflicts
https://github.com/vjmuzik/FNET

I've done as much testing as I could using the normal examples and some of my own sketches, so far they all appear to work as intended with no changes except for sketches that make direct calls to w5100.h. This instance of FNET is not multithreaded like my other examples have been, so this uses one IntervalTimer to poll the stack every 1ms in the background. Also in an effort to make sure this compiles from a fresh install I made a portable Teensyduino instance, installed libraries straight from GitHub, and tested it so I can confirm that it should compile without issues.

Because I tried to maintain compatibility with the standard Ethernet library some impact to the performance may have taken place.

Wow! This wrapper looks good. :D i'm running my UDP/TCP tests....

Ok,I again updated post #108 with FNET numbers using arduino wrapper. All looks good except when T4.1 is sending TCP. Sketch sends 100 1000-byte records but TCP receive on linux only reports receiving 68584 bytes ??

I was able to use flying leads for T3.6 and T4.0. I don't know why it wouldn't work with T4.1. User error is the best explanation, but unsatisfying.

Yes, maybe we can try to modify the PAD settings, and set them to a lower speed ("SPEED" and "DSE" Bitfields)
But this requires more intensive testing and we need to make sure it has no negative impact for other users.
 
Wow! This wrapper looks good. :D i'm running my UDP/TCP tests....

ntp drift test (UDP)
Code:
     ntp 3797960422.015705  rtt 189 us   -7 ppm over 10 s
     ntp 3797960432.015986  rtt 193 us   -7 ppm over 20 s

Can I get a link to the test sketch so I can see what’s going on? Receiving more than it’s sending sounds like a problem.

well, sketch says its sending 100,000 bytes (100 x 1000), but tcpdump shows it just stops sending at some point. I'm still looking at the packet trace. here is test sketch
https://github.com/manitou48/teensy4/blob/master/fnet_perf.ino
sketch contains various tests, just uncomment the one you want to use. I tried adding client.flush() before client.stop() no change. TCP tests on your earlier FNET libs worked just fine.
test program is based on my earlier wiznet tests (e.g. W5500)

tcp_send() is the test you want to run. i just tried using fbench.exe on win10 as the receiver. same problem, only 68584 bytes arrive

packet trace show strange MSS from FNET (should be 1460?)
192.168.1.113.8888 > 192.168.1.4.5001: Flags , seq 192001, win 2048, options [mss 2048,wscale 0,eol], length 0
Commentiing out MSS setopt in Nativesocket.cpp fixes MSS problem (1460), but the tcp send is still only sending 68584 bytes ????

Or the more general defs.h solution which allows even more ;)

Me and a few others are suggesting these things since years - without any reaction from Paul.

I commented on this just a couple days ago on another thread, and I have done so many times over the past years. The notion that I have said nothing is absolutely false. Perhaps the situation is that I have not given the desired answer, so the words I have written were forgotten?

Arduino has consistently rejected this proposal. I personally have mixed feelings about it, though I do generally agree with their concerns about the long-term API consequences. So far, and certainly for the short term (definitely version 1.52) I'm continuing to follow their lead on this.

So at least for now, the answer is no. Please, remember that I say no. Do not say I didn't answer.
 
Yup, that comment and others were about Arduino - not Teensyduino - if I remember correctly.
Teensyduino is full of (wanted) changes to Arduino.

Edit: I don't see how storing per project settings in TD would affect the Ardunio APIs.

Edit: ok, I read your edit with your "NO" :)
 
I don't know where those errors are coming from, I can't seem to reproduce it on my normal installation or my portable installation of Teensyduino 1.52 B4.

This is with the never before failed TSET CmdLine build. I emptied sketchbook\libraries except for FNET and NativeEthernet. I get the same errors from fresh github p#310.

NOTE: IDE Portable does not affect the TSET CmdLine build to use the 'Portable' folder.

Opened IDE 1.8.12 and built "T:\tCode\libraries\FNET\examples\FNET_Native_Ethernet\FNET_Native_Ethernet.ino" to work.

Had to get a refresh of ::

Then I can build USB_HOST to work :: "T:\tCode\libraries\FNET\examples\ASIXEthernet_Test\ASIXEthernet_Test.ino"

<EDIT> @vjmuzik - those folders both have a second INO >> " Functions.ino "
- wondering if that is the problem as most sketch folders have a s single INO and then CPP file for other sources?

I found the problem, I was incorrectly reporting the number of bytes being written to the wrapper, so the wrapper was thinking it was sending the whole 100,000 bytes when it actually wasn't. Also the MSS is normal now, I forgot to reset it after I was done doing some other testing.
 
@defragster - any chance you can update your code in post #287 with your Sparse option.

@mjs513 (@all with PSRAM on T_4.1: added a variant of the posted SparsePrint() here in the write function to replace - with NO writes to SD card.
Code:
void WriteBinary(volatile struct datrec *drp, size_t numstructs) {

//	dataFile.write((uint8_t *)drp, numstructs * sizeof(datrec));

	Serial.printf(" \t BUFF at %lX\n", drp );
uint32_t lastM = 0;
	uint32_t kk,lastB = 5;
	uint32_t ii = 0, iiL = 0;
	lastB = drp[0].byteswritten;
	for ( kk=0; kk<numstructs; kk++) {
		if ( lastM != drp[kk].millitime || lastB != drp[kk].byteswritten ) {
			if ( lastM != drp[kk].millitime )
				lastM = drp[kk].millitime;
				
			if ( ii != iiL ) {
			Serial.printf("skipped %lu\t", ii);
			Serial.printf("%lu, %lu, %lu, %lu\t", drp[kk].millitime, drp[kk].microtime, drp[kk].DWTCount, drp[kk].byteswritten);
				Serial.printf(" \t kk==%lu  ????\n", kk );
			}
			iiL = ii;
			ii = 0;
		}
		else
			ii++;
	}

	//dataFile.write((uint8_t *)drp, numstructs * sizeof(datrec));

#ifdef USE_EXFAT
// sync() updates directory and puts SD card in low-power idle mode
// it increases the block write time to 6-10mSec, since the file system
// must wait for the long block write to finish before it can update the
// directory and put the SD card into idle mode
// Without the sync, the block write returns in 0.88mSec on T3.6 at 168MHz
// because all the multi-block write stuff happens in interrupt routines in
// the SDFat driver.
// Sync() will reduce power consumption by about 20 to 40mA in the ~1 second
// between block writes. That can be significant for low-power loggers.

//    dataFile.sync(); // uncomment for slower writes, but reduced SD power
#endif
}

it shows the ???? anomalies if tested before or after the dataFile.write() - or with NO datafile.write() !!!!

So the corruption is not from write occurring during logging - or from SD write/read fail - but just misplaced data into PSRAM????
Showing this with above WriteBinary() code replaced in posted code:

Stopping logging


Quick read of that:
- skipped ## means the first value after that (millis) changed after ## repetitions, it should show groups of 19, with 20 data logs per millisecond - and then 19 repeats after the change.
- the end digit ,0 or ,1 should coincide with what buffer the data was written into by the _isr():: ADCChore(void)

A given 'Writing dbuff#' should only be looking at one buffer or another so whatever is written should have the SAME # - those are bold, the ones not bold are same buffer - where the millis tick crossed a buffer so the group skip size is not 19.

Above example output shows same sized disturbance of Skip 0 then skip 9, a longer run now is always skip 7 then skip 0 - so that changes.
>> What is repeating on restarts here is that it is always 1's in the zero buffer????

You can check my pointer allocation - but dbuff0 precedes dbuff1 - and both should be safely long enough and not near the start or end of PSRAM, and should be safely on a 32 bit boundary ( though prior check##() that didn't matter for read/write )

Kraaaap - just thought of something and have to repost both blocks the above
The error is always at the same offset in the buffer ???? >> kk==16384 ???? ???? which is HEX 0x4000
>> another run the error was at 16385, next run back to 16384

Also just added this to CODE above showing buffer address to be certain where that offset relates to:

<EDIT>
Made the buffer smaller so once could fit in RAM1 and the other in RAM2 and this works, then changing back to PSRAM fails at the same point:
Code:
#define SAMPLERATE 20000
[B][COLOR="#FF0000"]//#define USE_PSRAM 1[/COLOR][/B]
#ifdef USE_PSRAM // 128KB apart
#define BUFFSIZE  9190*2
const char *logfilename = "TIMELG_R1.DAT";
#include <extRAM_t4.h>
extRAM_t4 eRAM;
//uint8_t config = 2; //0 - init eram only, 1-init flash only, 2-init both
//These have been replaced with defines for:
//INIT_PSRAM_ONLY
//INIT_FLASH_ONLY
//INIT_PSRM_FLASH
uint8_t config = INIT_PSRAM_ONLY;
struct datrec *dbuff0 = (datrec *)0x70050000;
struct datrec *dbuff1 = (datrec *)0x70090000;
#else
//#define BUFFSIZE  1024
#define BUFFSIZE  9190*2
const char *logfilename = "TIMELOG1.DAT";
[B]struct datrec dbuff1[BUFFSIZE];
//struct datrec dbuff1[BUFFSIZE];
struct datrec *dbuff0 = (datrec *)malloc(BUFFSIZE*sizeof(datrec));[/B]

#endif
Tried with either in RAM1 or RAM2 and neither show the failure - so it doesn't seem to be a problem in the _isr() logic writing to the wrong buffer, but something on the PSRAM boundary ?

Just tested the T4.1 (and T3.6) for recording uBlox F9P GPS data (NMEA RMC messages) at 20 Hz to SD. Works like a champ, with Pete's help on some code mods. See this thread "Stream Data from Serial1 to SD Card, Teensy 3.6" under the Technical Support forum area for details.

Whats interesting is that the kks' show that the problems are occurring at the same index number. Also assuming that that the 0 or 1 indicate the buffer?
