C2000 Bootloader

The Torrox C2000 CAN bootloader enables fast, reliable in-field firmware updates for Texas Instruments TMS320 microcontrollers. Each bootloader is configured to your exact project requirements at compile time — you send the parameters, we deliver the binary and the documentation.

Reliable CAN Bus Firmware Updates for TI C2000

For products built around TI’s C2000 real-time control microcontrollers, the ability to update firmware after deployment is often the difference between a serviceable system and a costly recall. The Torrox bootloader provides a robust, field-tested update path over the CAN bus (or UART/SCI), without requiring physical access to a JTAG interface.

Why Choose the Torrox C2000 Bootloader

• Robust by design. Every firmware image is verified by CRC before launch. The bootloader will never start a corrupted application. Read more about our bootloader architecture and the design decisions behind it.
• Small flash footprint. The bootloader occupies approximately 16 KB, leaving the rest of the flash for your application.
• Configurable at compile time. Peripheral pins, communication parameters, oscillator frequency and other project-specific parameters are set once and built in.
• Smart client architecture. Protocol complexity lives in the host-side client, so the on-target bootloader stays as simple as possible. This keeps it robust and makes the protocol fully testable.
• Cross-platform tools included. A command-line client runs on Windows, macOS and Linux and supports multiple CAN/USB adapters out of the box.
• Easy integration. Example linker scripts and merge tools make it straightforward to combine bootloader and application into a single hex file for production flashing — as described in our Bootloader in Production post.

Supported Devices

The Torrox C2000 bootloader currently supports all variants of the following TI C2000 families:

• TMS320F2806x
• TMS320F28002x
• TMS320F28003x
• TMS320F28004x
• TMS320F280015x
• TMS320F2837xS
• TMS320F2837xD
• TMS320F28P55x
• TMS320F28P65x

We plan to further expand this list. So if you didn’t found your particular device in that list, contact us to get information as to when we plan to support your device.

How It Works

After a reset, the bootloader runs first. It listens on the configured interface (CAN bus or UART/SCI) for a brief time window, looking for instructions from a client. If no update is initiated, the bootloader verifies the CRC of the installed firmware and then hands control to the installed application. If an update is requested, it erases the application flash, receives the new firmware block by block, and stores a CRC over the complete image before starting the new firmware.

This boot-first design ensures the device can always recover, even after a failed update — no bricking, ever.
