TMS320F28377D: Uniflash CLI Program CPU2

TMS320F28379D: Uniflash CLI Program CPU2

Part Number: TMS320F28379D
Other Parts Discussed in Thread: UNIFLASH

I created a batch script for the TMS320F28379D dual core microcontroller using the Standalone Command Line generator in Uniflash v4.3.1.1835.  The programming of CPU1 using the resulting dslite.bat file is successful.  The programming of CPU2 fails when calling the generated batch script file for CPU2.  I have included the output of the batch file below.  Is there a way to utilize the generated batch script from the Uniflash Command Line option to program CPU2? 

many thanks for your response

    Samuel,

    From the error messages that you copied, looks like the error is from CPU1_CLA1.
    Which CPU are you trying to load?

    Can you share your batch script (if it is ok to share)?

    Thanks and regards,
    Vamsi

    Samuel,

    As noted by Vamsi, "-n 1" actually talks to the CLA1 core; "-n 2" would refer to CPU2 instead.

    That being said, there is a bug that prevents the UniFlash command line from working correctly for the these devices. This is because access to CPU2 requires connecting to CPU1 first, which the command line does not support right now. This is being tracked internally and is targeted to be fixed in UniFlash 4.5, targeted for release at end of September.

    As for workarounds, apart from using the GUI to access CPU2, the other workaround is to use Debug Server Scripting (DSS), which is the scripting language we have in CCS and is also accessible within UniFlash. Please read the following wiki page to learn more about how to set up DSS in UniFlash:

    processors.wiki.ti.com/.../UniFlashv4_DSS

    Once you set this up, you should be able to write a script that connects to CPU1 and then loads a program to CPU2.

    More information on DSS here:
    processors.wiki.ti.com/.../Debug_Server_Scripting

    Please let me know if you have any questions on this.

    Thanks,
    Ricky

    Vamsi, Ricky

    Many Thanks for your reply.

    I will use the GUI so far and wait for release 4.5.
