TMS320C672xx -- SPRS277C patch questions and EABI compatibility

Rick Bogdan

Other Parts Discussed in Thread: SPRC203

1)      SPRS277C indicates all code requires sprc203 ‘system patch’ and that a minimum of 0x2048 32-bit words are required for the patch. 

Does this patch need to be applied to only the code that runs from the initial TI Bootloader?  Or to all code?  the SecondaryBootloader and application code ?

2) this patch seems to be old and not EABI complicant,  is that true ?  Would the source be available to recomplie and support C6000 EABI ?

    Rick,

    The system patch needs to be applied to all applications before creating the AIS boot image. The patch can be applied in the same way that you would link any other static library or object file to the project in CCS. Having added the patch, the bootloader will jumps to the code section and executes this code at device reset before proceeding with the boot sequence.

    We cannot distribute the source code for this patch directly on the forums so I have sent the source code for the patch to the public email you have mentioned on your profile. Even though the C6000 compiler now support C000 EABI (ELF), I believe most of the software on the device is BIOS 5 based which supports only COFF binaries. Is there some reason why you need to generate an ELF version of this patch?

    Let me know if you received the source for the patch.

    Regards,

    Rahul
