Issue with floating point textures

I try to use an floating point texture using the latest driver 5.0.11.p8.41671 on the GC880 with OpenGL es 3.0 support. Shortly after uploading with

glTextureImage2D(GL_TEXTURE_2D, 0, GL_RGB32F_EXT, width, height, 
0, GL_RGB, GL_FLOAT, dataPtr);

i get an Segmentation Fault. Maybe it went wrong as the texture data is accesed during the shader process.


What am I doing wrong here? If the texture is given as byte array everything wents well.


Thanks in advance.
