CCS/TMDSEVM6657: File loader verification failure

Negin Madani

Part Number: TMDSEVM6657

Tool/software: Code Composer Studio

I have a problem loading a program on my C6657 EVM. I get this error (CCS 6.1.2.00015):

C66xx_0: File Loader: Verification failed: Values at address 0x0000000088000000 do not match Please verify target memory and memory map.

C66xx_0: GEL: File: C:/...\project2.out: a data verification error occurred, file load failed.

I have another C6657 EVM and have tried loading the same program on the two EVMs using different emulators. I have narrowed down this issue as being specific to one of the EVMs. I have gone through this Data Verification Errors guide and tried validating the memory by launching the target manually. So far I have found that the memory is probably misconfigured since the data randomly changes at random locations when I hit the refresh button in Memory Browser:

"To confirm if the data is valid (which would indicate a properly configured memory), click on the refresh button of the Memory Browser: if the numbers change randomly, the data is probably invalid."

How can I fix this? Any suggestions would be appreciated.

Anyone?

Hi Negin,
EVM boards should be tested when the are produced in the factory but occasionally we do see problems once they are delivered. Can you attempt to initialize the memory at a slower speed like 1066MT/s to see if this is an assembly error of an issue with the memory?
Thanks, Bill

Hi Negin,
Has there been any progress with this issue? Should I leave the thread open?

Hi Bill,

Thanks for getting back to me. How can I change the memory speed?

Hi Negin,
The PLL settings to change the speed are in the standard Gel file. I've asked one of the software guys to post instruction on how to change the memory speed.

Hi,

Please see the ccs_8_0_0\ccsv8\ccs_base\emulation\boards\evmc6657l\gel\evmc6657l.gel. Inside the Global_Default_Setup_Silent(), a function is called:
// Setup Pll2 DDR3 PLL @ 667 MHz
Init_Pll2(PLLM_DDR, PLLD_DDR);
where
/* DDR PLL settings for 1333 MHz */
unsigned int PLLM_DDR = PLL2_M;
unsigned int PLLD_DDR = PLL2_D;

See the table:
// +--------------------+---------------+--------+--------+
// | DDR3 PLL VCO | (CLKIN) Input | | |
// | Rate (MHz) | Clock (MHz) | PLL2_M | PLL2_D |
// +--------------------+---------------+--------+--------+
// | 1600 | 50 (EVM) | 63 | 1 |
// | 1333 | 50 | 79 | 2 |
// | 1066 | 50 | 63 | 2 |
// +--------------------+---------------+--------+--------+

#define PLL1_M 19
#define PLL1_D 0

#define PLL2_M 79
#define PLL2_D 2

So using PLL2_M = 63 and PLL2_D = 2 should reduce the DDR speed to 1066MHz.

In CCS6.1.2, you can find the same GEL.

Thanks for the instructions. I changed the DDR speed to 1066 MHz and repeated the test. Loading still fails.

I looked at the memory browser with a binary view and noticed that specific bits flip when I refresh the memory. What could this mean?

Thanks,
Negin

Hi Negin,

I could be an issue with the assembly of the board. Are all the bits associated with a single memory device? It sounds like you need to return the board as defective and get a new one.

The bit flips only happen throughout the DDR3 EMIF Data. Is there a guideline for the return/replacement process?

Thanks,
Negin

Hi Negin,

You can start with this information from the TI store. I will see if there is something specific that must be done for EVMs.
