TMS320F28069F: C2Prog Sector Violation for CLA RAM

Mashrur ALam

Hello

I am able to flash my CLA enabled code on my device using CCS. However when I try to flash using C2Prog I get this error:

Reading the SPRS698I document I know that CLA Program needs to reside in 0x9000 (region L3). I also C2Prog only supports saving code to flash memory so I made my linker file save the CLA code to flash then load to RAM at startup.

MEMORY

{

PAGE 0:

BEGINRAM: origin=0x0, length=0x2

PRAM: origin=0xC000, length=0x2000 //L5

CLA_PROG_RAM: origin = 0x9000, length = 0x1000 //L3

OTP: origin=0x3d7800, length=0x3fa

BEGINFLASH: origin=0x3D8000, length=0x2

APPHDR: origin=0x3D8002, length=0xC

FLASH: origin=0x3d800e, length=0x1Bff2

…

PAGE 1:

RAMM0M1: origin=0x2, length=0x7fe

CLA1_MSGRAMLOW: origin = 0x1480, length = 0x000080

CLA1_MSGRAMHIGH: origin = 0x1500, length = 0x000080

CLA_DATA_RAM: origin = 0x8000, length = 0x001000 //L0, L1, L2

DRAM: origin=0xe000, length=0x6000

}

SECTIONS

{

....

Cla1Prog : LOAD = FLASH,

RUN = CLA_PROG_RAM,

LOAD_START(_Cla1funcsLoadStart),

LOAD_END(_Cla1funcsLoadEnd),

LOAD_SIZE(_Cla1funcsLoadSize),

RUN_START(_Cla1funcsRunStart),

PAGE = 0

CLAscratch :

{ *.obj(CLAscratch)

. += CLA_SCRATCHPAD_SIZE;

*.obj(CLAscratch_end) } > CLA_DATA_RAM,

PAGE = 1

CLA1mathTables : LOAD = FLASH,

RUN = CLA_DATA_RAM,

LOAD_START(_Cla1mathTablesLoadStart),

LOAD_END(_Cla1mathTablesLoadEnd),

LOAD_SIZE(_Cla1mathTablesLoadSize),

RUN_START(_Cla1mathTablesRunStart),

PAGE = 1

}

Then on startup I copy Cla1Prog and CLA1mathTables to program RAM and data RAM respectively.

void c2000_flash_init(void)

{

#if MW_RUNTIME_FLASHLOAD

// Copy InitFlash function code and Flash setup code to RAM

memcpy(& RamfuncsRunStart,&RamfuncsLoadStart, (Uint32)(&RamfuncsLoadEnd-&RamfuncsLoadStart));

#ifdef CLA_BLOCK_INCLUDED

memcpy(&Cla1funcsRunStart, &Cla1funcsLoadStart, (Uint32)&Cla1funcsLoadSize);

memcpy(&Cla1mathTablesRunStart, &Cla1mathTablesLoadStart, (Uint32)&Cla1mathTablesLoadSize);

#endif

// Call Flash Initialization to setup flash waitstates

// This function must reside in RAM

InitFlash();

#endif

}

What could be causing the C2Prog error?

Mashrur,

Since you did not share the entire linker cmd file, not sure if anything else is mapped at 0x9000. Could you check if anything else (other than Cla1Prog) is mapped to CLA_PROG_RAM in your linker cmd file? Please check your map file to know what exactly is mapped at 0x9000.

Did you get any warning when you compiled? Warning like "creating output section without a sections specification" or anything else?

Thanks and regards,

Vamsi

I was able to fix the issue by moving CLA1_MSGRAMLOW, CLA1_MSGRAMHIGH, CLA_DATA_RAM to page 0.

I am now able to flash over CAN.
