I am trying to load the code into the C28f335 flash then copy it to the RAM and run the code.
I am using "spraau8" and it does not work. I am using an example that has in the sysctrl.c file: #pragma CODE_SECTION(InitFlash, "ramfuncs");
void InitFlash(void)
{
EALLOW;
//Enable Flash Pipeline mode to improve performance
//of code executed from Flash.
FlashRegs.FOPT.bit.ENPIPE = 1;
// CAUTION
//Minimum waitstates required for the flash operating
//at a given CPU rate must be characterized by TI.
//Refer to the datasheet for the latest information.
#if CPU_FRQ_150MHZ
//Set the Paged Waitstate for the Flash
FlashRegs.FBANKWAIT.bit.PAGEWAIT = 5;
//Set the Random Waitstate for the Flash
FlashRegs.FBANKWAIT.bit.RANDWAIT = 5;
//Set the Waitstate for the OTP
FlashRegs.FOTPWAIT.bit.OTPWAIT = 8;
#endif
#if CPU_FRQ_100MHZ
//Set the Paged Waitstate for the Flash
FlashRegs.FBANKWAIT.bit.PAGEWAIT = 3;
//Set the Random Waitstate for the Flash
FlashRegs.FBANKWAIT.bit.RANDWAIT = 3;
//Set the Waitstate for the OTP
FlashRegs.FOTPWAIT.bit.OTPWAIT = 5;
#endif
// CAUTION
//ONLY THE DEFAULT VALUE FOR THESE 2 REGISTERS SHOULD BE USED
FlashRegs.FSTDBYWAIT.bit.STDBYWAIT = 0x01FF;
FlashRegs.FACTIVEWAIT.bit.ACTIVEWAIT = 0x01FF;
EDIS;
//Force a pipeline flush to ensure that the write to
//the last register configured occurs before returning.
asm(" RPT #7 || NOP");
}
but I am getting the warning in the compile
"warning: creating output section "ramfuncs" without a SECTIONS specification"
I think that is the reason for it not to work but I am not sure how to correct it.
Thanks
