Serial flash utility is not working for davinci evm dm6446

also check the below link : I have tried these steps too -->

Hi,
Apologize for your issue got solved yet.
Could you please tell which application are you flashing ?
Simple LED flashing on NOR flash ?

If yes, which core are you using ?
If ARM, then why you need UBL code stuff here ?

Please answer to the above questions to proceed further.

Surely we will solve your problem.

Hi,

1) I am using arm core also I want to use DSP too since I have to use this for video application. I am trying on spectrum digital EVM DM6446. DSP Part no.: TMS320DM6446AZWT (its a dual core right?)

2)I am trying to flash a sample LED code with a UART message , my application is as below:

I tx a message from target immediately it enters to main, and then I set LEDs, I want to flash these codes to my NOR flash so that this code should run automatically when I power up the board.
(I wrote this to ensure the UART and board working).

main()

{
UART_PUTCHAR("HELLO");
SetLEDs();

}

So I tried generating a bin file of my application and flashing it with serial utility.
(in UART mode:
erase flash
flash the code

in NOR mode:
check the console in terminal also see the LEDs.LEDs are not glowing and also console is as in the previous message)

correct me if I am wrong in this procedure. guide me the right way to do this.

Azhagiri

Hi Azhagiri,

I tx a message from target immediately it enters to main, and then I set LEDs, I want to flash these codes to my NOR flash so that this code should run automatically when I power up the board.
(I wrote this to ensure the UART and board working).

Did you use JTAG for running this LED code ?

Could you please attach the complete project (library and include files) that worked with DM6446 EVM through JTAG mode.

LED_UART Test_Azhagiri.rarHi,

Yes, I download the code/ run on DDR using JTAG Emulator (Spectrum Digital XDS560 v2 LC traveller ) to run the LED code. please find my sample code also refer the note included with it, ignore the function names here, I have attached the workspace and project name led.

Hi Azhagiri,
Thanks.

Could you please try the following method.

I) Debug the UBL and LED code through CCSAzhagiri

1) Try to change the "entry point" address (0x81080000) to your actual binary "entry point" as per your *.map file.
Ex:
If your LED binary entry point is "0x80007490" then use this entry point address in UBL code to jump and waiting to execute.

2) Firstly, write some value at DDR address (Ex: 0x88000000) in LED code plus LED blinking stuff.

3) Build the code and convert into binary (.bin)

4) Load this binary to DDR memory using "Load memory" option in CCS (Ex: "0x80000000") as per your *.map file.

5) Now, load UBL ( entry point "0x80007490") code in CCS and run.

6) Check now, LED is blinking and check DDR address (0x88000000).

I don't have debugger for DM6446 EVM board to check this.

Please let me know if stuck with any step and for any understanding.

Hi, thank You I will try these steps and will update you. I have a small doubt in

" 1) Try to change the "entry point" address (0x81080000) to your actual binary "entry point" as per your *.map file.

Ex:

If your LED binary entry point is "0x80007490" then use this entry point address in UBL code to jump and waiting to execute."

Where exactly, In which file should I change the entry point? I have downloaded Utility source code "DM644x_FlashAndBootUtils_2_00" from link :  

DM644x_FlashAndBootUtils_2_00.tar.gz

is that fine?

I could not find the line where to change the entry point. can you plese explain?

Regards,

Azhagiri

Hi Azhagiri,

I think, it will be from "norboot.c"

gEntryPoint = hNorHeader->entryPoint;

I would like you to debug the UBL code and find where "entry point" get set and define then ensure this change in "norboot.c" is okay.

Thank You,
That's correct, I got "gEntryPoint = hNorHeader->entryPoint; " in 'norboot.c ' but I was not getting the step from where it gets the address.
I will check that in debugging and get back to you.

I have tried to debug, by loading ubl_nor.out file. and also giving following error in ubl.c file and I am not sure about changing these address can you please help me?

gmake: Target `all' not remade because of errors.

<Linking>

>> Compilation failure

**** Build Finished ****

Ok, I have removed another NOR.cmd file which was included in the folder, hope this solve my issue

I have complied the code and tried to run but it is not allowing me to run or debug, the run icon goes hidden as soon as I load the UBL_NOR.out file plese refer the screenshot attached.

1) I have made "DM644x_FlashAndBootUtils_2_00" folder itself as my Workspace folder

2) Imported UBL_NOR.pjt to CCS v 5 by "File->Import->legacy ccs 3.3 projects"

3) added a target configuration file testconfig.ccxml

4) It has automatically linked all the library files and source files excluding DM644x/CCS/Ubl/include folder  which is missing and could not find but there was no error for that, I assumed it is not needed

5) compiled the project

6) started debug option and loaded UBL_NOR.out and run option has gone hide, also could not set any breakpoints and could not debug it

(usually pointer goes to main()  and allows me to debug or run)

Whats wrong here? need to take other project ?

regards,

Azhagiri

Hi,
To confirm, could you try to flash this UBL.bin which is converted from UBL.out to DM6446EVM board.

Yes I could able to flash but I get below message on terminal after flashing this,

BOOTME BOOTME BOOTME BOOTME BOOTME BOOTME BOOTME BOOTME BOOTME BOOTME BOOTME BO

I'm able to flash and boot with my new entry address without any problem (but not able to make LED blink).
What are all other changes you made ?

USED Flash Utility version: DM644x_FlashAndBootUtils_2_00

1)

C:\DM644x_FlashAndBootUtils_2_00\DM644x\GNU>sfh_DM644x.exe -h

TI Serial Flasher Host Program for DM644x

-----------------------------------------------------

1)Erase flash: in UART Boot mode ( 1110 )
C:\DM644x_FlashAndBootUtils_2_00\DM644x\GNU>sfh_DM644x.exe -erase -flashType NOR -targetType DM6446

2)Flash the NOR flash: 

C:\DM644x_FlashAndBootUtils_2_00\DM644x\GNU>sfh_DM644x -flash -flashType NOR -targetType DM6446 -appStartAddr 0x80008674 -appLoadAddr 0x80000000 ubl_DM6446_NOR.bin led.bin

 

Here I have changed only  ppStartAddr 0x80008674 . Which was taken from the map file of my compiled led code :

 

OUTPUT FILE NAME: <led.out>
ENTRY POINT SYMBOL: "_c_int00" address: 80008674

Azhagiri

 

 

 

Hi,
Use the following commands alone since we have modified the "entry point address" in UBL code itself, so we are expecting "led.bin" should get loaded on address which we used as "entry point"

sfh_DM644x.exe -erase -flashType NOR -targetType DM6446
sfh_DM644x -flash -flashType NOR -targetType DM6446 ubl_DM6446_NOR.bin led.bin

Hi,

I am still not able to modify the entry point in the UBL code as explained in my arlier code.. I am not able to debug the code shall I assign the entrypoint value manually and try?

Regards,

Azhagiri
