Part Number:TMS320F28035
Tool/software: TI C/C++ Compiler
I am building a project based of the 3803xLEDBlink example. I have added my code which compiles but does not link. I did some searching and I find
//----------------------------------------
#ifdef __cplusplus
#pragma DATA_SECTION("SysPwrCtrlRegsFile")
#else
#pragma DATA_SECTION(SysPwrCtrlRegs,"SysPwrCtrlRegsFile");
#endif
volatile struct SYS_PWR_CTRL_REGS SysPwrCtrlRegs;
in DSP2803x_GlobalVariablesDef.c. I have found enough information to think I need to add something to my section in the linker cmd file but I no not sure what to do next. This my cmd file.
Any help?
