Don’t know what’s wrong with the problem, in target board running an application, several warning will come up like below:
Alignment trap: PC=0×40e2ef50 Instr=0xe5853000 Address=0×000468e9 FSR 0×813
and the application could run normally. QT version 4.7.0, default QT lib should be 4.6.2 works fine.
temporary solve:
echo 2 > /proc/cpu/alignment
anybody could tell how to solve this by recompile this problem?
