    Snooze not working with any T4.x on TD1.56

    I haven't tested this on older versions of Teensyduino, but I get the same behavior on a Teensy 4.0, 4.1 and MicroMod when compiling and uploading from TD1.56

    I took the following example code and uploaded it to each Teensy and get the same behavior - the boot led will blink 9 times.
    I can also confirm this happens when just including the Snooze library in the sketch, and not actually initializing any of it's components.

    Obviously something has changed in the recent versions of TD that would cause the teensy to not even boot up.

    Code:
    /*************************************************
      This example uses the Bounce library to make sure
      the button is still pressed for 3 seconds after
      waking up from low power mode. If it released
      before the 3 seconds are up, go back to sleep.
      Supported Micros: T-LC/3.x/4.0

    I've just come across this problem today as well. I updated to TD1.56 today and I get them same symptoms when I include the snooze library into my sketch.

    Did it work on 1.55/1.54?

    @Rezo - I know I am sticking my nose in here without good facts but I ran into the same problem using @FrankB T4_PowerButton library (the original one before the last update). Using Arduino 1.8.19 and TD1.56. If I included T4_PowerButton.h I would get the 9 blinks from the red LED (T4.1). Using Franks last version, there was no problem. Comparing the two versions and doing a process of elimination I discovered that the function "startup_early_hook()" in the original library was causing the problem with the latest 1.56 TD. That function was not used in Frank last version of T4_PowerButton. In the snooze library I see in "hal.c" the same function "startup_early_hook()". Maybe it's causing the same conflict with TD 1.56 that I saw. I have not played with the Snooze library at all but thought I would mention it

    Not sure if this is the reason here, in this special case:

    Startup-c has a bug. There is (often) an interrupt happening, quite early , in the first lines of startup.c
    Paul didn't want to insert my proposed change, so this is still the case.
    Teensy crashes, because the interrupt happens before the interrupt vectors are set.
    Fix: Disable the interrups as very first step, and re-enable them somewhere after the loop that sets the interrupt-vectors. (use a volatile asm .... ::memory" to be sure everything got written)

    But..as said.. I did not investigate this special case. Quite possible that it has an other reason. I' don't fix things anymore. Too much effort for a 1% chance that a fix gets merged.

    Disable them after this line:
    Code:
    void ResetHandler(void)
    {
        unsigned int i;
    !!here!!
    enable them here:
    Code:
        // set up blank interrupt & exception vector table
        for (i=0; i < NVIC_NUM_INTERRUPTS + 16; i++) _VectorsRam[i] = &unused_interrupt_vector;
        for (i=0; i < NVIC_NUM_INTERRUPTS; i++) NVIC_SET_PRIORITY(i, 128);
        SCB_VTOR = (uint32_t)_VectorsRam;
    !!here!!

    I've gone back to T1.53 and A1.8.13 which is working as normal again

    @Tim, probably something wrong with your install.
    I do not get linking errors with T4.0 / TD1.56 - only two warnings:
    Code:
    C:\Arduino\hardware\teensy\avr\libraries\Snooze\src\hal\TEENSY_40\SnoozeCompare.cpp: In member function 'virtual void SnoozeCompare::disableDriver(uint8_t)':

         IRQ_NUMBER_t IRQ_CMP;
                      ^

    @Frank B where are these functions referenced from?
    And how would I enable/disable all interrupts?
    Should I use NVIC_ENABLE_IRQ(n) and NVIC_DISABLE_IRQ(n) and loop through the IRQ_NUMBER_t range?

    @TimChown I get the same warning as frank, but no errors.

    __disable_irq()
    __enable_irq()

    These are global, take no parameter, and disable/enable _all_ interrupts (but NMI)

    Thank you @Frank B, I appreciate it!
    Will test later on and come back with insights

    With TD1.56 I don't get error linking that's just TD1.55.
    With 1.56 I get the 9 flashes of the boot LED.

    I've got a deadline coming up so going to stick with 1.53 for now but will play about with the interrupts after that. Good luck!

    @Re: 9 Blinks:
    it works for me to just add a FLASHMEM to TEENSY40\hal.c (Line 652):
    Code:
    //----------------------------------------------------------------------------------
    FLASHMEM
    void startup_early_hook( void ) {
        uint32_t OR_D_GPR = IOMUXC_GPR_GPR4 | IOMUXC_GPR_GPR7 | IOMUXC_GPR_GPR8 | IOMUXC_GPR_GPR12;
        if ( OR_D_GPR > 0x0 ) {
            IOMUXC_GPR_GPR1 &= ~IOMUXC_GPR_GPR1_GINT;

            IOMUXC_GPR_GPR1 &= ~IOMUXC_GPR_GPR1_GINT;
    I ended up coming back to this and this fixed it. Thanks you Frank!

    Placing this function is FLASHMEM worked for me too.
    I did see a similar solution to the 9 blinks on a recent thread yesterday while searching for the root cause.

    Good find and fix Frank! I was just reading the startup code the other day and it notes that the early_hook is called before code copied from FLASH to ITCM so it has to be marked FLASHMEM to run from there.

    Hello, not sure if this is related problem

    Snooze examples (this case: Snooze\examples\deepsleep\button_hold_wakeup )
    not compiling with T3.6/LC/T4, with USB Type: "MTP Disk experimental" chosen , while choosing the default "Serial" it's fine
    Code:
    arduino-1.8.19\hardware\teensy\avr\libraries\Snooze\src/hal/TEENSY_40/SnoozeUSBSerial.h:56:39: error: 'usb_cdc_line_rtsdtr' was not declared in this scope
             return usb_configuration && ( usb_cdc_line_rtsdtr & USB_SERIAL_DTR ) && ( ( uint32_t )( systick_millis_count - usb_cdc_line_rtsdtr_millis ) >= 15 );
                                           ^
    arduino-1.8.19\hardware\teensy\avr\libraries\Snooze\src/hal/TEENSY_40/SnoozeUSBSerial.h:56:61: error: 'USB_SERIAL_DTR' was not declared in this scope
             return usb_configuration && ( usb_cdc_line_rtsdtr & USB_SERIAL_DTR ) && ( ( uint32_t )( systick_millis_count - usb_cdc_line_rtsdtr_millis ) >= 15 );
                                                                 ^

             return usb_configuration && ( usb_cdc_line_rtsdtr & USB_SERIAL_DTR ) && ( ( uint32_t )( systick_millis_count - usb_cdc_line_rtsdtr_millis ) >= 15 );
                                                                                                                            ^
    I've looked into it a bit,
    but it cannot be easily bypass by declaring the three missing inside "SnoozeUSBSerial.h",

    tested on 1.8.19&TD1.56

    Okay I saw it's not updated for some time,
    With "Serial" chosen it's not working properly with and will reset before going through setup();

    The old version of snooze without the USBserial-snooze block can still work with "MTP_experimental" used
    so its fine with my old LC sketch,

    I guess I will need to dig further on the datasheet to work this time on my new sketch with T4
