    This 'padding' is interesting note about the 32KB blocking for ITCM : .text.itcm.padding 8548 24220

    Yup, the padding is somewhat useful.

    If I think of the 1770... these things will be much much worse..
    I'm not that sure the whole builder is usable... not sure if it is able too compile different files (two cores) with different flags and math-libraries.. (FPU)
    If not, it would be needed to call it twice.
    Building will take ages.. :-( Edit: I think it will end with #ifdef IMXRT1170_CORE0 [...] #elseif IMXRT1170_CORE1 [...] and calling the compiler twice. However, all the other things the builder does, like detecting the libraries will be problematic.

    It will take a decade for Massimo to take these things into account in the builder. If a decade is enough.

    Hi Paul,

    could you please take a look at usb_dec.h?
    I think the config for USB_MTPDISK_SERIAL is wrong. My Lubuntu (dmesg) says:
    Code:

      #define ENDPOINT5_CONFIG    ENDPOINT_RECEIVE_INTERRUPT + ENDPOINT_TRANSMIT_INTERRUPT  // ????
    Now, Linux seems to be happy, but I'm not entirly sure, that it is correct now.
    Thank you!

    Edit: After a while, it continous to write:
    Code:
    cdc_acm 1-1:1.1: failed to set dtr/rts
    Not sure, if this is normal.

    Then, lsusb needs a long time (several seconds) to display the verbose info for the Teensy (tested with USB_MTPDISK_SERIAL only) and sometimes fails to prints the strings (serial-no, manufacturer etc)

    @Paul - Playing with my old dev machine that has Ubuntu 20.04 on it and I think up to date.

    I have Arduino 1.8.13 with this beta, and maybe having issues with SEREMU connections working to Arduino Terminal monitor.

    I started this up to test out some MTP stuff and could not debug output to terminal monitor:
    More details about this in the thread: https://forum.pjrc.com/threads/43050...l=1#post269826

    Then I wondered if it was specific to MTP, so I configured USB Type to keyboard, loaded the Simple sketch:
    Modified only to add: while (!Serial && millis() < 5000) ;

    actually edited again to comment out the keyboard prints as they were getting annoying

    Code:
    int count = 0;
    
    void setup() {
      while (!Serial && millis() < 5000) ;
      Serial.begin(9600);
      delay(1000);
    }
    
    void loop() {
      // Your computer will receive thesHello World 0e characters from a USB keyboard.
      //Keyboard.print("Hello World "); 
      //Keyboard.println(count);
    
      // You can also send to the Arduino Serial Monitor
      Serial.println(count);
    
      // increment the count
      count = count + 1;
    
      // typing too rapidly can overwhelm a PC
      delay(5000);
    }
    It then does not want to be programmed automatically again by upload: Teensy verbos info:

    Now, Linux seems to be happy, but I'm not entirly sure, that it is correct now.
    Thank you!

    Edit: After a while, it continous to write:
    Code:
    cdc_acm 1-1:1.1: failed to set dtr/rts
    Not sure, if this is normal.

    Then, lsusb needs a long time (several seconds) to display the verbose info for the Teensy (tested with USB_MTPDISK_SERIAL only) and sometimes fails to prints the strings (serial-no, manufacturer etc)

    Frank,

    I will take a look. I believe this is not stuff in the current build, but stuff you added in from @WMXZ files in the MTP_t4 project? There are probably a few other things I want to double check to see as it compares to some other fixes I did for the
    SEREMU one which is in the build.

    And I may want to try it out anyway on Ubuntu as to get some debug working.

    It can't read the device strings, sometimes.

    Hi Paul,
    I think FreqCount() is flawed. The gating period appears to not be set by the call to FreqCount.begin(NuSec).
    Or am I being stupid (as usual)?

    T4.1 on custom PCB with very good signal conditioning.
    Main code is many thousands of lines... but boils down to this:


    Code:
    /*
        Name:       FreqCountBug_01.ino
        Created:    10/02/2021 17:42:50
        Author:     DESKTOP-KBCLAD0\Richard
    */
    #include <FreqCount.h>
    
    
    void myDelay(int milliseconds) {
    	long time_end = millis() + milliseconds;
    	while (millis() < time_end) {}
    }
    
    
    void setup() {
    	Serial.begin(57600);
    	Serial.println("Hello....");
    	FreqCount.begin(100);  // Gate time in uSec.
    }
    
    
    void loop() {
    	unsigned long count;
    	if (FreqCount.available()) {
    		count = FreqCount.read();
    		Serial.println(count);  // Display the measured frequency
    
    
    		/* Displayed frequency shows the gate time is NOT
    		set by <FreqCount.begin(100)> but DOES correspond
    		with the interval set by myDelay()
    
    
    		Ex : 10MHz input should show 100 * 10 = 1000
    		Actual value is 17000139
    
    
    		Comment out the call to myDelay() and all is well.
    		*/
    
    
    	}
    
    
    	// This delay simulate a lot of other things happening in real app.
    	myDelay(1700); // Strange delay time makes malfunction obvious.
    }

    This got rid of that Linux error message. I updated the interface to match the MIDI versions, and I did verify on Ubutu that the Serial monitor is working with this setup...

    Ok, Kurt, thanks for the confirmation - your version has the same values as mine.

    (EDIT: you probably should skip ahead to my followup post before sinking time into reading this...)

    I'm trying to adapt some filesystem code that was SD-specific to be filesystem agnostic, so it can be used with SD and LittleFS on both the Teensy and ESP32. I need to be able to pass a FS reference to a function. A function like this (taken from ESP32 example code) compiles on the ESP32 but not with Teensyduino 1.54 beta 6.

    Code:
    void listDir(fs::FS &fs, const char * dirname, uint8_t levels);
    This level of C++ is beyond me; I'm not sure what that code does let alone how to troubleshoot the errors. I get these errors when compiling:

    Code:
    SD_FS_test:8: error: variable or field 'listDir' declared void
     void listDir(fs::FS &fs, const char * dirname, uint8_t levels){
                  ^
    SD_FS_test:8: error: 'fs' has not been declared
    SD_FS_test:8: error: 'fs' was not declared in this scope
     void listDir(fs::FS &fs, const char * dirname, uint8_t levels){
                          ^
    SD_FS_test:8: error: expected primary-expression before 'const'
     void listDir(fs::FS &fs, const char * dirname, uint8_t levels){

    Here's the full test sketch that works on ESP32 and doesn't compile for Teensy 3.6:

    Code:
    #include <FS.h>
    #include <SD.h>
    
    #define SD_CS BUILTIN_SDCARD
    //#define SD_CS 5
    
    void listDir(fs::FS &fs, const char * dirname, uint8_t levels){
      Serial.printf("Listing directory: %s\n", dirname);
    
      File root = fs.open(dirname);
      if(!root){
        Serial.println("Failed to open directory");
        return;
      }
      if(!root.isDirectory()){
        Serial.println("Not a directory");
        return;
      }
    
      File file = root.openNextFile();
      while(file){
        if(file.isDirectory()){
          Serial.print("  DIR : ");
          Serial.println(file.name());
          if(levels){
            listDir(fs, file.name(), levels -1);
          }
        } else {
          Serial.print("  FILE: ");
          Serial.print(file.name());
          Serial.print("  SIZE: ");
          Serial.println(file.size());
        }
        file = root.openNextFile();
      }
    }
    
    
    void setup() {
      Serial.begin(115200);
      delay(1000);
      
      if (SD_CS >= 0) {
        pinMode(SD_CS, OUTPUT);
      }
    
      // initialize the SD card at full speed
      if (!SD.begin(SD_CS)) {
        Serial.println("Card Mount Failed");
        while(1);
      }
    
      listDir(SD, "/", 0);
    }
    
    void loop() {
    }
    I specifically need this for improvements to the GifDecoder library

    Is there something missing from the SD to SdFat wrapper code that could be added to get this to compile?

    Sure enough directly after posting this I found the issue... The ESP32 FS library uses a namespace for some reason. If I change
    Code:
    fs::FS &fs
    to
    Code:
    FS &fs
    it works fine. I don't know why they are using a namespace or if it's a good or bad thing. Based on my other experience with ESP32 libraries I'm guessing making their code compatible with existing Arduino libraries wasn't a priority.

    This line might be relevant: https://github.com/espressif/arduino.../src/FS.h#L117

    I think my issue is fixed and I'll just remove the namespace from GifDecoder. I'm leaving this here in case it's actually a good thing to add namespaces to the Teensyduino version of the FS library.

    @PaulStoffregen - Again wondering has anyone had any luck with Ubuntu 20.04 with USB Types that include SEREMU to have the Arduino Terminal Monitor?
    As I posted earlier in this thread. It did not work for me with the MTP disk one, and then tried with Keyboard and again Arduino monitor shows offline...

    Note: when I added the stuff for MTP with Serial, that works...

    I don't know. The only Ubuntu 20 issue on my radar is the problem you found with ARM64 on Raspberry Pi. Are there threads where people have reported problems on normal x86 Ubuntu 20?

    I'm still on Ubuntu 18 here, but considering updating to 20 soon. Maybe it's time....

    Maybe? First off you might try running a simple keyboard test (I commented out the outputs to keyboard ...) and see if it work there...

    Note: code I ran in #29

    Hm I thought I try the Teensy LC audio again.. something seems to be broken with the current code from Beta6.
    I'll look.... maybe my PR did not include all needed changes.

    Windows can restore old versions. I replaced the current core with an older one, from december... and LC Audio works again.
    Any Idea what has changed that can cause problems? With the current core I hear distorted audio.
    It is NOT the Audio Library.

    Edit: ok. I'll find that...

    I thought I would mention I installed on MAC (the big whole version of Arduino installed...) and the keyboard test I mentioned, the SEREMU appears to work.
    I do get the apple system saying it wont install the keyboard until it knows what type of keyboard and I supposed to press the button to the right of ...
    But Teensy Monitor showed the pass numbers.

    Now Mac is doing an update...

    @Paul on the test I grabbed an old portable that had Ubuntu 14.04 and installed Ubunt 18.04 installed latest Arduino and this beta build and then tried plugging in the T4.1 with the keyboard app that I programmed on the Mac and it shows I believe same issues as the Ubuntu 20.04.

    It is showing in arduino terminal monitor as offline

    Edit: I should mention I also did switch to T4.1 and reprogrammed the Teensy. It failed to reboot the Teensy, I had to hit the program button, which programmed it.

    It still showed the Teensy offline. I tried programming again and again I had to hit the program button

    Code:
    warning: #warning "Please include TimeLib.h, not Time.h.  Future versions will remove Time.h" [-Wcpp]

    Has existed for years.
    Isn't it time to finally do that....?

    It shows up in Linux as MTP device, which is obviously not fuctional. Is this by intention?

    Hi all,

    I hope this is the right place to post this issue with the Entropy Library.

    The implementations of these two defined functions in the Entropy.h are missing in the Entropy.cpp file:
    Code:
    uint8_t randomByte(void);
    uint16_t randomWord(void);

    I added them in to my local files like this (in case anyone needs this):
    Code:
    uint8_t EntropyClass::randomByte(void)
    {
      return random8();
    }
    
    uint16_t EntropyClass::randomWord(void)
    {
      return random16();
    }
    Thanks

    Tested B6 with Radiohead library and two NRF24LO1 modules with LNA and power amplifiers. Good comms between T4.0 and T4.1 at default power and SPI settings over about 30 feet inside the house. The Teensies and modules are on plugboards and powered by the T4X 3.3V power.

    I did the default RH_NRF24 instantiation and initialization:
    Code:
    #include <SPI.h>
    #include <RH_NRF24.h>
    
    const char compileTime [] = " Compiled on " __DATE__ " " __TIME__;
    // Singleton instance of the radio driver
    RH_NRF24 nrf24;
    // RH_NRF24 nrf24(8, 7); // use this to be electrically compatible with Mirf
    // RH_NRF24 nrf24(8, 10);// For Leonardo, need explicit SS pin
    // RH_NRF24 nrf24(8, 7); // For RFM73 on Anarduino Mini
    
    void setup() {
      Serial.begin(9600);
      delay(400);
       Serial.printf("NRF_24 Server %s\n", compileTime); 
      if (!nrf24.init())
        Serial.println("init failed");
      // Defaults after init are 2.402 GHz (channel 2), 2Mbps, 0dBm
      if (!nrf24.setChannel(1))
        Serial.println("setChannel failed");
      if (!nrf24.setRF(RH_NRF24::DataRate2Mbps, RH_NRF24::TransmitPower0dBm))
        Serial.println("setRF failed");    
    }
    An important note: With this default initialization, the library expects the CE signal to be connected to Pin 8 on the Teensy. I think it is possible that some of the earlier posts noting difficulties with the NRF24 may have connected the CE signal to the wrong pin, or were mixing up the CE and SPI CS pins.


    A less important note: A lot of the the examples in the Radiohead library supplied with the TD install still have sketches with the .pde extension. That's so 2014!!!

    Hi,

    Just to say thanks for this release.
    Band limited waveforms + clean Freeverb = big improvement for synths projects !

    @Paul:
    NOTE for SD update to SdFat : transferred Arduino/Teensy drive contents to new machine here
    > Build pulled in Adafruit_SDFAT library instead of the Teensy one, had to delete that ( used for their NRF family )
