TI Launchpad F28069M interrupt hello world example

Note: this project does not use the HAL

This simple example set a CPU timer of 1 sec and prints on the serial common interface (SCI) something like:

Hello World! 1 
Hello World! 2 
Hello World! 3 
Hello World! 4 
Hello World! 5 
...

Setup

Import the css folder. The result should be like the bottom image:

The files outside of src folder should be linked from C2000Ware package.

Example: ~/ti/C2000Ware_3_01_00_00_Software/device_support/f2806x/common/include

Write program into Flash or RAM (not permanet)

The linker file (cmd) will determine address locations on your board.

To write the program into FLASH use the xxx_boardName_xxx.cmd

Instead, to write the program into RAM use the xxx_boardName_xxx_ram_lnk.cmd

Example on Flash:

The path location is:

 ~/ti/C2000Ware_3_01_00_00_Software/device_support/f2806x/common/cmd

Load function from Flash to RAM

C28x Compiler - Understanding Linking

Speeding up flash-based embedded applications

If running from Flash, specify what function to compy on RAM:

#pragma CODE_SECTION(Flash_Init, “ramfuncs”);

Copying the functions into RAM at start-up

/* Copy time critical code and Flash setup code to RAM
*  The  RamfuncsLoadStart, RamfuncsLoadSize, and RamfuncsRunStart
*  symbols are created by the linker. Refer to the project.cmd file.
*/
memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (Uint32)&RamfuncsLoadSize);
