XMC4500 byte alignment

[lkormos]

Hi,

I have a XMC4500 custom board and a working code witch was created under DAVE eclipse softver.

I build my project under VisualGDB, but it is not working perfectly becouse of packed structures. I tried adding “-fpack-struct” to flags, but i got hard fault when the program trying to access hardware registers (-fpack-struct=4 is working fine, but i need byte alignment).

Is there any solution?

Regards,

Kormos L.

Hi,

Yes, please try setting __attribute__((packed(number)) on the specific structures that need to be packed.

You can also try this build [http://sysprogs.com/files/tmp/VisualGDB-5.3.8.1797.msi]. Once you click ‘details’ in the embedded memory explorer, it will show struct sizes and field offsets directly in the code.
