I have have done what u suggested ie duplicating the aspen platform as toolchain
and replacing the frameworks with the 1.14 , it was possible to switch platforms
for devices but could not get it working with header link problem (tried to put a header link in each framework) and also after several switches from 1.2 to 1.1.4 I could not get armV6 back , have to reinstall sdk
So what did u more precisely ?
Is it also possible to get the simulator working for "<1.2 coding"?
