DSP/BIOS version 5.33 or greater has been modified to be compatible with the latest Code Generation Tools, this includes:

• Any version of 5.0.x and 5.1.x for the C2000 Code Generation Tools
• Any version of 4.1.x and 4.2.x for the C5500 Code Generation Tools
• Any version of 6.0.x and 6.1.x for the C6000 Code Generation Tools
• Version 6.1.x will issue a linker warning regarding the use of trampolines for certain DSP/BIOS calls (only affects C62x, C67x, C672x). This is a known issue and will be addressed in future DSP/BIOS releases. This does not affect functionality.

DSP/BIOS 5.33 can be obtained from the Update Advisor DSP/BIOS Product Releases page:
