Hi
I tried installing version 2.20, but when I start CCS5.4 it complains that I have version 2.22 installed, so it will not install 2.20.
I really doubt that it would Work though, since C66 is not mentioned before version 2.21. This leds me to conclude that I will have to update my legacy DSP/BIOS code to SYS/BIOS.....bugger!
