I found this which says you can actually read internal Vref even if it's tied to external Vdda. So this means that you can offset any error from Vdda since Vref int is known and calibrated.Jimis

The fact that I get 0x8020a0a at the disassembly should be good which means that jump has succeeded but how can I debug further ? I can't understand what the assembly is doing and can't see C code. Is there a way to put a breakpoint at the beginning ...

Fixed that too Thanks :) It still stops at some point later (0x8020a0a) but at least we made some progress.
