Binary of VisualDSP++ 5.1.2 is not matched with binary of VisualDSP++5.0.7 for same source code

Category: Software
Product Number: VisualDSP++
Software Version: 5.1.2

Hello, All,

I am using Blackfin processor BF537 for our product range. I have updated VisualDSP++ software version 5.0.7 to 5.1.2. I have found that output binary compile with both software version are not matching for same source. I have seached a lot but not getting any clue. So is there any different setting required to compile source code with latest VisualDSP++ 5.1.2? Or if someone faced same issue and got solution then please share. Or share your idea. I appreciate if i will get clue atleast from you. Thank you.

  • Hi

    VisualDSP++ build tools (compiler, assembler, linker) have undergone a number of changes in the period since VisualDSP++ 5.0 through to VisualDSP++ 5.1.2 in the form of improvements and bug fixes, as have the supporting libraries (C Runtime Libraries, DSP Libraries, etc) that are linked into your application.

    It is very unlikely that the generated files will be identical to the build on VisualDSP++ 5.0; the code will be functionally correct, but the generated assembly will likely be quite different from your old build.


  • Hi, Thanks for reply.

    You are correct that this changes expected. But I have further debug and found that custome board not booted up completly. It hang up in system_init function. Specifically I can say that it stuck in adi_ssl_Init() function. So, PC never touch application code. One thing I want to say that this source code is working fine when complied with VisualDSP++ 5.0.7 version. If anyone worked and faced issue, solved it then they can help out me. I appreciate all response. Thank you.
