Using The Teensy Loader on Mac OS X. Update: Teensy 3.0 is supported by Teensyduino. After installation, Teensy Loader is in hardware/tools. The Teensy Loader is also available in a command line version for advanced users. It works on Mac, Windows, Linux and BSD Unix. It works on Mac, Windows, Linux and BSD Unix. So here's the scenario. I have sent my teensy 3.1 circuit to a client of mine And now I need to update the code burned onto teensy without providing client access to the code So is it possible to create an exe or an installer of a kind which on execution simply upload the new code onto the teensy? Since the code is finally a hex file uploaded onto the controller I hope this must be possible But on doing a quick google search i was not able to find any valid resource which would guide me how to go about it. Teensy Loader - Command Line Version# The Teensy Loader is available in a command line version for advanced users who want to automate programming, typically using a Makefile. For most uses, the graphical version in Automatic Mode is much easier. Compiling From Source The command line version is provided as source code for most platforms. To compile, you must have gcc or mingw installed. Edit the Makefile to select your operating system, then just type 'make'. If you have a BSD compatible make, replace 'Makefile' with 'Makefile.bsd'. Version 2.0 has been tested on Ubuntu 9.04, Mac OS-X 10.5, Windows XP, FreeBSD 8.0, OpenBSD (20-Jan-2010 snapshot), and NetBSD 5.0.1. All versions of NT-based Windows with USB support (2000 and later) are believed to work. On Ubuntu, you may need to install 'libusb-dev' to compile. Sudo apt-get install libusb-dev Other Linux systems may to compile. Usage and Command Line Options A typical usage from the command line may look like this: teensy_loader_cli --mcu=mk20dx256 -w blink_slow_Teensy32.hex Required command line parameters: --mcu=: Specify Processor. You must specify the target processor. Book logo design. This syntax is the same as used by gcc, which makes integrating with your Makefile easier. Valid options are: --mcu=mk66fx1m0: Teensy 3.6 --mcu=mk64fx512: Teensy 3.5 --mcu=mk20dx256: Teensy 3.2 & 3.1 --mcu=mk20dx128: Teensy 3.0 --mcu=mkl26z64: Teensy LC --mcu=at90usb1286: Teensy++ 2.0 --mcu=atmega32u4: Teensy 2.0 --mcu=at90usb646: Teensy++ 1.0 --mcu=at90usb162: Teensy 1.0 Caution: HEX files compiled with USB support must be compiled for the correct chip. If you load a file built for a different chip, often it will hang while trying to initialize the on-chip USB controller (each chip has a different PLL-based clock generator). On some PCs, this can 'confuse' your USB port and a cold reboot may be required to restore USB functionality. When a Teensy has been programmed with such incorrect code, the reset button must be held down BEFORE the USB cable is connected, and then released only after the USB cable is fully connected. Optional command line parameters: -w: Wait for device to appear. When the pushbuttons has not been pressed and HalfKay may not be running yet, this option makes teensy_loader_cli wait. It is safe to use this when HalfKay is already running. The hex file is read before waiting to verify it exists, and again immediately after the device is detected.

Perform a hard reset using a second Teensy 2.0 running this code, with pin C7 connected to the reset pin on your main Teensy. While this requires using a second board, it allows a Makefile to fully automate reprogramming your Teensy. This method is recommended for fully automated usage, such as Travis CI with PlatformIO. No manual button press is required! -s: Use soft reboot (Linux only) if device not online. Perform a soft reset request by searching for any Teensy running USB Serial code built by Teensyduino. A request to reboot is transmitted to the first device found. How can i get arabic language package for word 2011 mac pdf. -n: No reboot after programming. After programming the hex file, do not reboot. HalfKay remains running. This option may be useful if you wish to program the code but do not intend for it to run until the Teensy is installed inside a system with its I/O pins connected. -v: Verbose output. Normally teensy_loader_cli prints only error messages if any operation fails. This enables verbose output, which can help with troubleshooting, or simply show you more status information. System Specific Setup Linux requires UDEV rules for non-root users. FreeBSD requires a for non-root users. OpenBSD's make is incompatible with most AVR makefiles. Use ' pkg_add -r gmake', and then compile code with ' gmake all' to obtain the.hex file. On Macintosh OS-X 10.8, Casey Rodarmor shared this tip: I recently had a little trouble getting the teensy cli loader working on Mac OSX 10.8.
