Hi Skip,
1. When you purchase the C5502 eZdsp, you can use CCS for free, unlimited, as long as it is used with the eZdsp.
2. DSP/BIOS is free and comes with some fairly basic examples

The connected audio framework is a more involved example that uses DSP/BIOS. This is built for C5505/15/35 however. C5502 is a different architecture, so it will not run this example without porting first.
3. A JTAG emulator is embedded on the C5502 eZdsp - XDS100 that allows free use of CCS.
4. You should reach out to your local sales rep to connect with additional phone support. We would like to keep our support limited to the forum. We dont loan tools out. All of the eZdsp tools are less than $100, including JTAG.
Why have you selected C5502? Have you considered C5505/15/35? These DSPs max out at 100 - 150Mhz, but since they are newer you will likely get faster support on this forum.
