1 Programming Fundamentals

Before programming a device, understanding how the non-volatile memory of C2000 devices works is necessary. Flash is a non-volatile memory that allows users to easily erase and re-program. Erase operations set all the bits in a sector to '1' while programming operations selectively set bits to '0'.

Flash operations on all C2000 devices are performed using the CPU. Algorithms are loaded into RAM and executed by the CPU to perform any flash operation. For example, erasing or programming the flash of a C2000 device with Code Composer Studio™ entails loading flash algorithms into RAM and letting the processor execute them. There are no special JTAG commands that are used. All flash operations are performed using the flash application programming interface (API). Because all flash operations are done using the CPU, there are many possibilities for device programming. Irrespective of how the kernels and application are brought into the device, flash is programmed using the CPU.
