Ah, I think I learned why it wasn't working. I believe it had something to do with the LDFLAGS that get set in the Makefile you mentioned. I appended the LDFLAGS listed in the Makefile to my configure command, and things seem to build building now: CC="arm-none-eabi-gcc -Os -Wl,--gc-sections...

To my knowledge, I am currently using the toolchain that is provided by the Teensduino installer: kelly in ~/Downloads/libsndfile-1.0.25 $ which arm-none-eabi-gcc /home/kelly/work/arduino-1.0.5/hardware/tools/arm-none-eabi/bin/arm-none-eabi-gcc kelly in ~/Downloads/libsndfile-1.0.25 $...

I would like to introduce logic in my teensy firmware such that I can read and write audio data to an SD card. I'm currently evaluating libsndfile, but I'm running into problems with cross compiling the library. When configuring libsndfile for cross compilation, it errors out while compiling a...

To be honest, I'm not entirely sure what the requirement would be for the "different combinations". Would the goal be to provide a certain subset of the supplementary objects such that it doesn't take up as much space as compiling against the entire suite? Maybe in that case there could be an...

Another update: I got my program compiling and running on my teensy3 as expected! The issue was that my Makefile was not grabbing any of the supplementary objects in the arduino-1.0.5/hardware/teensy/cores/teensy3 directory. I've updated my Makefile to reflect the changes for anyone who is...

I downloaded the latest teensyduino suite, and tried my hand at compiling the example listed therin, and after compiling and uploading on my Arch machine, it seems to be working nicely :) I even used my Makefile in the same directory, and it produces similar results. The issue now however, is...

Another update: As a sanity check, I decided to use the arduino IDE to compile and upload an example to my teensy. After successfully compiling and uploading the example programs, my teensy is behaving as expected. It appears that these operations are working on my Arch machine, so I'm less...

Just tried compiling my program using the same toolchain on an 64-bit release of Ubuntu 12.04. It successfully compiled, and it appears to have uploaded to my Teensy without an issue. My program however, still does not appear to be running as intended :( Any other pointers / things to...

At first glance, it doesn't look like I'm using any software obtained from pacman or aur repositories to build my teensy program; my arm-none-eabi toolchain seems to be a custom build from PJRC. Is there anything in specific that I should be looking for to diagnose this issue further?

Yup. Arch, 64-bit.

You're correct that I don't want to use the Arduino IDE. In fact, I don't want to use *any* IDE; I want to develop solely with a text editor and the teensy_loader_cli. I understand the value that Eclipse might bring to the table, but I would rather struggle with a Makefile at this point than...

Hello World Teensy 3.0 without Arduino Hello there! I've seen a few forum posts on here on how to compile and upload sketches to Teensy 3.0 without using Arduino, but most of them never seem to be resolved or otherwise have become inactive. I've munged together some of the previous efforts...
