Hi,
I have installed the Patch, the CD Image : CD_STM32-Primer_20100909   , and I updated from CircleOS 4.03 to Version 4.1. 
Debugging ist only possible without CircleOS up to Adress 0x8008000, I have tested it with an old bigger project(Made with Rlink-Pro), and stepping/debugging  this program behind this limit is not possible with  the Evoprimer.
