• Tiiiiiiiildd... - Transmits a classical extended data frame
• diiildd... - Transmits a FD base data frame without bit rate switch
• Diiiiiiiildd... - Transmits a FD extended data frame without bit rate switch
• biiildd... - Transmits a FD base data frame with bit rate switch
• Biiiiiiiildd... - Transmits a FD extended data frame with bit rate switch

Building

Firmware builds with GCC. Specifically, you will need gcc-arm-none-eabi, which is packaged for OS X, and Linux on Launchpad. Download for your system and add the bin folder to your PATH.

Your Linux distribution may also have a prebuilt package for arm-none-eabi-gcc or gcc-arm-none-eabi, check your distro's repositories to see if a build exists. Simply compile by running make.

Flashing with the Bootloader

Plug in your CANable2 while boot pins are shorted with jumper. Neither the blue nor the green LED should be illuminated. Next, type make flash and your CANable will be updated to the latest firmware. Unplug/replug the device after moving the boot jumper back, and your CANable2 will be up and running.
