CCS/TMS570LS3137: About FLASH ECC and RAM ECC

Hello Whong,

You don't need to add the memory for ECC to CMD file if you don't use linker CMD to generate ECC.

If you want to generate ECC using Linker CMD, yes, both flash and it's ECC should be put in CMD file. For example:

MEMORY
{

VECTORS (X) : origin=0x00000000 length=0x00000020 fill = 0xffffffff

FLASH0 (RX) : origin=0x00000020 length=0x001FFFE0 vfill = 0xffffffff
FLASH1 (RX) : origin=0x00200000 length=0x00200000 vfill = 0xffffffff
/* Bank 7 (128kB, FEE) */
FLASH7 (R) : origin=0xF0200000 length=0x00020000 vfill = 0xffffffff

STACKS (RW) : origin=0x08000000 length=0x00001500
RAM (RW) : origin=0x08001500 length=0x0007db00

/*RAM (RW) : origin=0x08001500 length=0x0007db00*/
SHAREDRAM (RW) : origin=0x0807F000 length=0x0001000

/* Bank 0 ECC */
ECC_VEC (R) : origin=(0xf0400000 + (start(VECTORS) >> 3)) length=(size(VECTORS) >> 3)
ECC={algorithm=algoL2R5F021, input_range=VECTORS}

ECC_FLA0 (R) : origin=(0xf0400000 + (start(FLASH0) >> 3)) length=(size(FLASH0) >> 3)
ECC={algorithm=algoL2R5F021, input_range=FLASH0 }

/* Bank 1 ECC */
ECC_FLA1 (R) : origin=(0xf0400000 + (start(FLASH1) >> 3))length=(size(FLASH1) >> 3)
ECC={algorithm=algoL2R5F021, input_range=FLASH1 }

/* Bank 7 ECC */
ECC_FLA7 (R) : origin=0xF0100000 length=(size(FLASH7) >> 3)
ECC={algorithm=algoL2R5F021, input_range=FLASH7 }

}

Thank you

run test Code 

else if(1 == step)
{

/* Run 1Bit ECC test on TCM RAM */
retVal = SL_SelfTest_SRAM(SRAM_ECC_ERROR_FORCING_1BIT, TRUE, &failInfoTCMRAM);
INCREMENT_PASS_FAIL_COUNTER(failInfoTCMRAM, retVal);
}
else if(2 == step)
{
/* Run Diagmode 1 */
retVal = SL_SelfTest_FEE(FEE_ECC_DATA_CORR_MODE, TRUE, &failInfoFlash);
INCREMENT_PASS_FAIL_COUNTER(failInfoFlash, retVal);

/* Run 1 bit selftest */
retVal = SL_SelfTest_FEE(FEE_ECC_TEST_MODE_1BIT, TRUE, &failInfoFlash);
INCREMENT_PASS_FAIL_COUNTER(failInfoFlash, retVal);
/* Run Diagmode 2 */
retVal = SL_SelfTest_FEE(FEE_ECC_SYN_REPORT_MODE, TRUE, &failInfoFlash);
INCREMENT_PASS_FAIL_COUNTER(failInfoFlash, retVal);
/* Run Diagmode 3 */
retVal = SL_SelfTest_FEE(FEE_ECC_MALFUNCTION_MODE1, TRUE, &failInfoFlash);
INCREMENT_PASS_FAIL_COUNTER(failInfoFlash, retVal);
/* Run Diagmode 4 */
retVal = SL_SelfTest_FEE(FEE_ECC_MALFUNCTION_MODE2, TRUE, &failInfoFlash);
INCREMENT_PASS_FAIL_COUNTER(failInfoFlash, retVal);
}

if I use the code above,I want to know whether need to add flash 7.

and I look some cmd code ,that 

 FEE (R) : origin=0xF0200000 length=0x00000064 fill=0xDEADBEEF /* For FEE testing, Valid only for sample application */

why fill 0xDEADBEEF?

Thank you

No  the  cmd .file

MEMORY

DO I need  to add flash 7?
