Original question:

TMS320F28379D: C2000 SCI Boot Loader returns error

TMS320F28376S: SCI flash bootloader

Rodrigo Stefanini

Part Number: TMS320F28376S
Other Parts Discussed in Thread: C2000WARE

Hello everybody,
I have a problem, with sending the firmware with SCI using the example version called (F2837xS_sci_flash_kernel),

I put the recommendations seen in other posts here, including in the CMD file, like the ALIGN(8) example for the sectors.
Another configuration made was so that the pins used correspond to my UART hardware, that is, the GPIO84 and GPIO85 pins are enabled.


The first used example version was (C2000Ware_4_01_00_00), that is, the current version.
The kernel sent to the TMS went correctly and the menu was presented.
When sending the command (1-DFU) the sending of the application itself starts, this process takes time and always ends without success.


I tested the kernel version (C2000Ware_2_01_00_00) for comparison and got a different error.

Now I have 2 questions:
1- How to fix this problem?
2- How to increase the application sending speed?

command sent:

serial_flash_programmer.exe -d f2837xS -k C:\Users\rodrigo.stefanini\Desktop\FIRMWARE_F28376S\F2837xS_sci_flash_kernel.txt -a C:\Users\rodrigo.stefanini\Desktop\FIRMWARE_F28376S\F28376S_application.txt -p COM79 -b 38400

    Hello, 

    Can you share your linker command file here? Using ALIGN(8) was the correct step, it will be good to confirm that the sector address shown above is aligned. When trying the older C2000Ware version, did you use the serial flash programmer from that same version? It looks like the serial flash programmer and flash kernel are from different versions. 

    Thanks

    Hello Anu, thanks for your repply,

    For context, I basically put ALIGN(8) in front of all the lines of the example sector present in C:\ti\c2000\C2000Ware_4_01_00_00\device_support\f2837xs\examples\cpu1\F2837xS_sci_flash_kernel\cpu01, in the file called flash_programming_RAM.cmd.
    To answer your question, yes, I'm using the same serial_flash_programming, being the latest version of C2000Ware. But now
    I'm focusing on the example of this latest version, so only using its serial_flash_programming.exe.

    The ALIGN(8) needs to be present on the linker command file of your firmware image (the image mapped to Flash), not the flash kernel image (which is mapped to RAM). Can you try it on the firmware image's linker command file and let me know what happens?

    True!? Today I won't be able to check this more closely, my work ends at 17:00, Brazilian time. My project doesn't have a linked command file built in, can I use either one? Just changing ALIGN(4) to ALIGN(8)? Next monday I will try it.

    Rodrigo, 

    Not sure what you mean when you say your project does not have a linker command file built in - how are you mapping it to Flash? Also, you should use ALIGN(8), not ALIGN(4).

    Thanks, Anu,

    Im new in this Texas world, today I found the linked file and resolve my issue.
