GCM70

Raptor GCM70

The GCM70 is a general purpose control module. The module has 2 CAN buses, and sports a 3-phase motor driver. The eclectic inputs and outputs make this module suitable for a wide variety of general purpose applications.

The GCM70 is part of a family of rugged, automotive-grade production controllers that use a software development process based on MATLAB/Simulink, known as Raptor-Dev. Raptor-Dev significantly speeds up algorithm development by using automatic code generation. In addition, developers can quickly test application software on their PCs with a built-in onscreen PC simulation.

FAQ

Non-Volatile Memory Corruption

Non-Volatile memory can be corrupted during a write if the module is improperly powered off (ie removing power from Batt+ (Pin 68)).

Calibrations

In production programs, it is recommended to store all calibrations in Flash memory (available within the "raptor_target_def" block).

Recovery Procedure (Boot Key)

The GCM70 requires a Boot Key to recover the module. These can be found on our store page

The use the boot key to recover the malfunctioned module, please follow the Raptor-Cal MotoHawk Module Recovery steps provided: Boot Key Recovery and below.

Notes:
The Boot Key signal (Pin E on the Smartcraft connector) needs to be connected to the SWG4 pin for the GCM70.
Once the bootkey is used, the module will default to a CAN baud rate of 250k, so update the Raptor-Cal settings accordingly.

Power Cycle Instructions:

• Step 1: Remove all power to the module by turning off Key switch and then power supply. Connect the Boot Key to the bus.
• Step 2: From Raptor-CAL/Service: Select Program, then the recover check box, MotoHawk, Select the .RPG file.
• Step 3: Click OK, turn on power supply, then key switch.

For a full list of steps, see the Raptor-CAL FAQ Page

Bootstrap

The GCM70 can be forced to remain in the firmware bootloader by applying a bootstrap sequence. The bootstrap sequence is:

Pin	State for Boot
AN1	High
AN2	High
AN3	High
AN4
AN5
AN6
AN7
AN8
AN9	Low
AN10	Low
AN11	Low
