Hi,
I don't have any prior experience with Teensy boards and I'm pretty newbie. I have one Teensy 4.0 board connected to a laptop which I don't have physical access to it but I have a ssh connection to the laptop so the only option for me to program the device is using teensy_loader_cli package.
I've successfully installed teensy_loader_cli and programmed the device for the first time using the following command with the available hex file example in the directory:
/teensy_loader_cli --mcu=TEENSY40 -s blink_slow_Teensy40.hex
and I confirmed that the LED toggles and every thing's OK.
In the next step I opened an example in Arduino:
/examples/Teensy/Tutorial3/HelloSerialMonitor
void setup() {
Serial.begin(38400);
}
void loop()
{
Serial.println("Hello World");
delay(1000);
}
I verify/compiled the code and export compiled binary file to the laptop and used the previous cli command to program the board, but I got this error and cli hangs in there:
"Error opening USB device: No error"
Well I know this was a bad code and I have to press the push button or reset the USB cable but why is it a bad code? Here is the Arduino Tools parameters for this sketch:
Board : "Teensy 4.0"
USB Type: "Serial"
...
