RTOS/TMS320C6747: Memory initialization and DSP BIOS versions

Darren Jenkins

Part Number: TMS320C6747

Tool/software: TI-RTOS

TI-RTOS team,

Our customer is working with C6747 on a product that has been in production for some time.  They recently changed build environments:

Old:
CCS 3.3
Compiler 7.3.10
DSP/BIOS 5.41

New:
CCS 6.2.0
Compiler 7.4.18
DSP/BIOS 5.42

It looks like there are problems where memory is not initialized as expected when accessing it.  They are using MEM_alloc(). 

They have imported the TCF file from the old project to the new, and are using this to define the heap size.  Do you have any advice on moving a project between these build environments?

The problem has already been discussed in another thread here:
e2e.ti.com/.../582283

Any other advice is welcome.

There have been some changes to the code as well, so we can't rule that out.

Thanks,
Darren

    Hi Darren,
    There have been no changes to the MEM module between BIOS 5.4.1 and BIOS 5.4.2. Also, MEM_alloc() does not initialize memory. Do you have more specific information about the problems they are facing?
    Best regards,
    Janet
