CCS/TMS320C6657: 6657 NAND BOOT

Part Number: TMS320C6657

Tool/software: Code Composer Studio

Hi ,I have some questions about C6657 direct ROM Boot.

Because the actual application is big, the client asks to write the program to nandflash.

The steps:

1, Modify the address in nandwrite.cmd to 0x80000000，Compile the nandwriter project provided by TI in CCS v5.2.1 (download from processors.wiki.ti.com/.../File:C6657_directROM_Boot_example.zip)，get a new nandwrite.out(we can name it nandwrite2018.out).

2，Convert the application led.out (we test with a led flashing applet) into led.dat .

The tool is in the folder nandboot/build (Including hex6x.exe).

3，Set bootmode to noboot mode, Operating in CCS：

Debug------open gel------connect------load program(load nandwrite2018.out)------load memory(load led.dat)------resume------Add dataSizeUint32 and value in Expressions

I load led.dat to the DDR3 (0x80000000), sometime the information of Console is “Data comparison failure at offset ……”, sometime the Console shows that is successful, but the program has not been running. (I guess the program don’t run in DDR3)

What is wrong with my operation ？？？

And,

If the address in nandwrite.cmd is 0x0c000000(MSM)------just like the original in the file provided by TI,

after programming into 0x0c000000(load memory),

the program run (LED flashing).

Hi,

Can you share which SDK version are you using?

Best Regards,
Yordan

mcsdk_2_01_02_06（on win10，CCS V7 , ti-cgt-c6000_8.2.2）
mcsdk_2_01_02_06 (on win7，CCS V5.2.1 ，c6000_7.3.4）

But I have never used SDK . ???

“1, Modify the address in nandwrite.cmd to 0x80000000，Compile the nandwriter project provided by TI in CCS v5.2.1 (download from processors.wiki.ti.com/.../File:C6657_directROM_Boot_example.zip)，get a new nandwrite.out(we can name it nandwrite2018.out).”

About this,I try it in CCS V7, but it's failure,

so I do it in CCS V5(c6000_7.3.4), I get a new file nandwrite2018.out successfully , and then......

This example nandwriter is developed to use MSM for writing the image for NAND boot demonstration only. Looks like, this does not initialize the DDR3.

Please use the nand writer available in Processor SDK to use the DDR3 for loading the image.

/* Memory address to store the write data */
#define WRITE_DATA_ADDRESS 0x80000000

Thank you.

Thank you ,Raja !

We know that example don't initialize the DDR3, so we edited a GEL file for application ,use it to initialize the DDR3.

After "Connect Target",the Console shows that DDR3 initialization is complete.

This is the link of our GEL file (don't need pass word):

Please share the map file for nandwriter and the flashing led application.

Thank you.

Thank you very much !

These are some files about Nand Boot we used.
In these folders, there is a .txt document for instruction.
and ,maybe you need to configure the path in CCS (Properties). As shown below:

Unable to access the above link. Please attach the nandwriter.map and led.map files here.

Thank you.

Thanks !

The system of E2E does not support uploading map format files

If you still can't open these links，could you send an E-mail to my registered account email ?And I can send you files by email.

Hi,Raja,
Forgot to tell you that there is no FPGA chip on our board.

We tried IBL in July, the programming did not report error, but the program(a APP of flashing LED) does not run.

At that time, we didn't know the operation process, we could only explore.

（The screenshot below shows the files we used.）

/cfs-file/__key/communityserver-discussions-components-files/791/0844.Fonn_5F00_Test-of-IBL.rar

So we test Direct Boot (without IBL) ,download the example from your website as I said before.

>>>> I hope you are following procedure to program the flash, Please confirm.

1. Launch the target configuration file.
2. Initialize the DDR3
3. Load and run nandwriter. out to program the flashing led application.

>>>> Another suggestion is to try the same procedure on EVM. I do not have any other suggestion for this issue.

One another suggestion,

Please use the TI CGT 7.x compiler and not TI CGT 8.2.2 compiler. The Compiler 8.2.2 has stopped support for COFF DSP binaries and when building with ELF, the compiler seems to be including certain assembly files that were written for COFF binaries.

Please note that MCSDK 2.x is a legacy baseline and we are only supporting Processor SDK RTOS based development for these devices on the E2E forums. The documentation for Processor SDK RTOS clearly highlights this need to use older compiler as you can see from here:
