Hy,
I have a problem to embedded QT4.4.3 on blackfin with uClinux.
my configuration of QT is
./configure -shared -depths 4,16,24,32 -no-cups -no-webkit -embedded bfin -little-endian -qvfb
I have build successfully and load the library and font in my kernel.
the problem is my frambuffer. the application that i have developed on QT3.3.5 running well but when i try to execute an example of QT4 ./sliders -qws
my kernel panic , i have this error :
QLinuxFbScreen::connect: No such device
Error: failed to map framebuffer device to memory.
