Hi Andreas,
The board does have floating point emulation . I even tried with
enablng float option while building the toolchain(gcc-3.4.5-glibc-2.3.6
,arm-9tdmi-linux-gnu-) . Still i face the same problem . Does the Directfb
code have any checking or code that could give floating point exception .
I am not really able to figure out if it could be the problem with the
compilation of the application or related to toolchain . if you could
suggest me any help .
