Sounds potentially like one of the standard things:
Look in your code, typically in setup that looks like:
while (!Serial) {}
or
while (!Serial) ;
That says wait forever until USB Serial is ready...
If I want...
A couple of additional points, that might help.
As mentioned, there are 8 hardware UARTS (LPUART) objects, but the number of the hardware UART does not necessarily correspond to the Serial object number.
That is...
Look at WireIMXRT.h/.cpp
You will find an area in it like:
#if defined(ARDUINO_TEENSY_MICROMOD)
PROGMEM
constexpr TwoWire::I2C_Hardware_t TwoWire::i2c2_hardware = {
CCM_CCGR2, CCM_CCGR2_LPI2C2(CCM_CCGR_ON),...
As mentioned in the Code Security page:

If you start up Arduino on your Ubuntu machine, and then use the file->preferences command,
the resulting dialog will...
@Sandro - Sorry, looks like that example fell through the cracks. I never used it. And there were several other examples for logging, such as SD_MTP-logger which do compile.
I will try to push up a version that...
Maybe post photos of your setup. It might help to see potential wiring issues and the like.
Things like bad solder joints, pins off by one. Pins not soldered to the Teensy. Maybe too long of wires, etc.
Also I...
The error message hopefully points you in the right direction:
32 | #error "You need to select USB Type: 'MTP Disk (Experimental)' or 'Serial + MTP Disk (Experimental)'"
You need to choose one of those two USB...
I would follow what @MarkT was implying.
If it were me, I would try something like:
void setup() {
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native...
That message is coming from the Joystick debug code.
Try editing joystick.cpp in the USBHost_t36 directory.
Look for:
//#define DEBUG_JOYSTICK
#ifdef DEBUG_JOYSTICK
#define DBGPrintf USBHDBGSerial.printf...
If you lower the SPI signal to a low enough speed, then yours might work better. Especially if you can get your analyzer running at a multiple of the SPi speed.
For example 4mhz or 6mhz probably 8.
As you mentioned, pins 7 and 8 (and 25) are all on PWM1 submodule 3.
As for independent, depends on what you want. You can have 3 different PWM signals with different duty cycles on these 3 pins. However, all three...
Sorry might help to know which type of Micro SD card module you are wanting to hook up.
That is there are those which use SPI to communicate with them. For example the one that is part of the Audio adapter....
You are free to use any digital IO pin you want for CS for SPI.
The SPI.setCS() pin is for those sketches and libraries that do more hardcore low level programming of the SPI interface.
For example some display...
If it were me, I would use the hard core sledgehammer approach.
Go into Arduino IDE: And uninstall Teensy boards.
Reboot machine to make sure nothing running.
Look in the Arduino15 directory I mentioned in my case:...
I am pretty sure that Paul was responding to your earlier post. Your post that mentioned Windows 10 was only posted a couple of minutes after your post with that information.
I know I have posted about that error...
Sorry, I don't own any MIDI equipment or have any expertise in that part of the USBHost code.
So for example I don't know anything about your device. For example, does it communicate over USB in Full Speed (12mbs)...
I can do some of it, using the Saleae Logic Analyzer, but it does not handle the 480mbs communications. I have a modified version of their USB LS/FS analyzer where I added support for High Level Analyzer(HLA) where I...
Sorry, I could be wrong, but my guess is it might be difficult to do with normal SPI.
That is the TCR register has field in it for clock phase, which is either leading or trailing edge. I don't see option for both....
Same thing just different location
on my machine W11 it is at: C:\Users\kurte\AppData\Local\Arduino15\packages\teensy\hardware\avr\0.59.3\libraries\Audio
Most likely slightly different location on your machine, as...
If you have not already done so, you might want to also post on the Arduino forums: https://forum.arduino.cc/latest
As hopefully one of the Arduino developers might have some better ideas on how to fix.
I am not a...
Look into your directory at: C:\Users\yukon\Documents\Arduino\libraries\
try removing any ILI9341_t3 stuff including one with name ending in master
ditto for the XPT...
Sorry I have no idea what version of the libraries you are using. Looks like the ILI9341_t3 library must be real old, as it does not look like it is setup to handle
T4.x, which I added during the T4 beta cycle.
Try...
I know that Arduino is starting to add some stuff, for unit testing, as was posted recently on the Arduino forum thread:
https://forum.arduino.cc/t/uarts-code-trying-to-enhance-the-performance-and-understand/1147711/23...
Sorry, have no idea how hard it might be to make the graphic cursors to work. Or if there was some hardware reason, that it was not done.
I see the registers are defined but commented out in the header file:...
The IMXRT boards that are used for the T4.x have built in Ethernet support.
The kit: https://www.pjrc.com/store/ethernet_kit.html
Which has pins to solder into the pins I roughly marked on the T4.1
These pins do...
You are probably right about those methods. I have not played with the RA8875 for awhile now. And I have not done anything with the graphic cursors. Hopefully someone who uses these displays, will chime in.
I...
Quick update:
Our ST7734_t3 github version of uncanneyEyes7735 does not currently compile on my machine.
Need to doublecheck - that is not just my install. But all of the graphic files appear to be at the root...
Sorry it has been a long time since I played with keyboard stuff.
But looking at code and the keyboard page: https://www.pjrc.com/teensy/td_keyboard.html

I could be completely wrong (it has happened before ;) )
But I am pretty sure, that all of the SD Cards ship with MBR (or at least that is the only thing that SDFat will be able to understand and that the partitions...
