CCS/TMDSCNCD280049C: Flash API download issue

Kevin Chen31

Part Number: TMDSCNCD280049C
Other Parts Discussed in Thread: C2000WARE, UNIFLASH

Tool/software: Code Composer Studio

Hi C2000 experts,

I would like to use flash api to implement a flash download function through UART (9600 baudrate).

The data format follows the "sci flash kernel", and all the flash download functions I used that derives from 

"..\c2000ware\driverlib\f28004x\examples\flash" example code.

I also create a test file "led_ex1_blinky.txt" to test this flash function.

However, when I test my code, I found an error returned from "Fapi_doVerify()", but not every time.

Below is the source file, and I check the flash contents using UniFlash after I downloaded.

The Fapi_doVerify() always return fail at address 0x8401C, but I can download the code using CCS through JTAG without error.

 

I am not sure if I miss anything or not?

May I have your help about this?

Please check the project and source file.

Thanks,

    Kevin,

    Your project shows you are using a RAM based linker cmd file "280049C_RAM_lnk.cmd". 

    But you mentioned you are loading to Flash.  I could not find the linker cmd that you are using in the package that you provided.

    In your linker cmd file, please try to align the start address of all the sections mapped to Flash on a 128-bit boundary (use ALIGN(8)). Let me know if it helps.

    Regards,

    Vamsi

    Hi Vamsi,

    Sorry, I don't know why the project uses the old one, I have updated the configuration of this setting.

    I uploaded two my projects, one is the bootloader, the other is the application.

    In bootloader, I use f28004x_bootloader.cmd, bootloader_entrytable.asm.

    In application, I use f28004x_application.cmd, application_entrytable.asm.

    And I also modified the f28004x_codestartbranch.asm for each project.

    I had aligned the start address of all the sections mapped to Flash on a 128-bit boundary in cmd file, but it still did not work well.

    May I have your advice about this? Thanks,

    Kevin,

    I checked the latest files that you provided and I still see that the sections are not aligned on 128-bit address.  Please use ALIGN(8) and not ALIGN(4).

    Thanks and regards,
    Vamsi

    Hi Vamsi,

    I had tested the code with aligning on 128-bit address, since it didn't work out.

    So, I attached the original code.

    Here is the modified code, please check it.

    Happy New Year!!

    Kevin,

    In your application linker cmd (not bootloader cmd), you grouped .cinit, codestart, .text, and .econst.  

    Please separate them.  Since .text started at 0x8401C (I saw in map file), this section is not 128-bit aligned.

    Thanks and regards,

    Vamsi

    Hi Vamsi,

    After I separated .cinit, codestart, .text, and .econst in .cmd file.

    .cinit : > APP_FLASH, PAGE = 0, ALIGN(4)

    codestart : > APP_FLASH, PAGE = 0, ALIGN(4)

    .text : > APP_FLASH, PAGE = 0, ALIGN(4)

    .econst : > APP_FLASH, PAGE = 0, ALIGN(4)

    I can download the program without error.

    Now, I am trying to generate CRC data to check the code integrity .

    Thanks for your kindly help.
