I wanted to let everyone know that a bug was discovered in the v4.3.3 of the Code Generation Tools (Compiler) that made USB enumeration fail on the USB example1 for the CCS3.3 examples. It most likely was causing other problems as well. The bug was carried through v4.3.4 and v4.3.5 releases. It has been fixed and the patch integrated into v4.3.6 which is available now on CCS3.x Update Advisor. It is recommended that everyone using the VC5504/05, C5504/05 and C5514/15 DSPs use this release of the Code Generation Tools.
Regards.
