CCS/TMS320F28335: TMS320F28335 IAP Example project

Vincent Hu

Part Number: TMS320F28335
Other Parts Discussed in Thread: C2000WARE, CONTROLSUITE

Tool/software: Code Composer Studio

Hi sir,

I am using TMS320F28335 to create an user bootloader project to upgrade user application area.

As i have no experience on TMS320F28335 (I used ARM7, Cortex-M3 before), so would you give a link to download the IAP example project of DSP28335 ? 

Sorry, i did not find the link to download such example.

BTW: i use CCS v6 IDE.

Thanks.

Best Regards,

Vincent

    Hi Vincent,

    Please refer C2000Ware package for referring to examples for F2833x. Let me know if this resolves your issue.

    Thanks

    Hi Vincent,

    there are several boot loaders in ROM (SCI, SPI, I2C, CAN). Refer to the TMS320x2833x, 2823x Boot ROM
    Reference Guide http://www.ti.com/lit/spru963

    Hi Vasudha,

    Thanks for your information.

    I have already setup C2000Ware_1_00_04_00_setup.exe ,but i did not find any IAP example in C:\ti\c2000\C2000Ware_1_00_04_00\device_support\f2833x\examples. 

    And i found some example in folder : C:\ti\c2000\C2000Ware_1_00_04_00\utilities\flash_programmers, but it seems could not be opened by CCS IDE.

    And there is no IAP example base CCS project ?

    Is there any existed CCS project i can use for reference it directly ?

    Thanks.

    Best Regards,

    Vincent

    Vincent,

    there are two sources for that.

    C2000 controlSUITE , see

    and the successor C2000Ware.
    Here check installation under c:\TI\c2000\C2000Ware_1_00_04_00\device_support\f2833x\examples\f28335_flash_kernel\
     - SCI_Boot.c
     - Share_Boot.c

    Hi Bernd,

    Sorry for reply later.

    I saw the example yesterday and i have some questions:

    1. Base on this example, boot mode should be SCI-A boot, right ? And base this boot mode, GPIO pins selection should be match for SCI-A boot mode ,instead of "Jump Flash", right?

    2. Since my user bootloader must run from start address of flash, so boot GPIO pins selection should be match for "Flash mode" (i think so).   Based on this reaseon, I think I must make a big change on this example about boot configuration, including below points :

    1) vector table modification:  this vector table should be different in bootloader project and appliation as my past experience, whether this DPS28335 has vector table re-map function registers ?    

    2) I think based on my applicaiton, the whole projects = bootloader project + application project . And boot GPIO pins should be "jump to flash" , so it can run user bootloader project to upgrade application project area.

    I do not know whether my understanding is right or not.

    Hope your response.

    Best Regards,

    Vincent
