Hi,
This is not directly related to U-boot, but since it happens in U-boot, I'm hoping someone here could help.
I have the U-boot up and running. Now I need to add new network protocols to it. They are also working fine except one little detail. The 32-bit word aligment is wrong.
The case is exatly the one described here: http://netwinder.osuosl.org/users/b/brianbr/public_html/alignment.html#q3
Processor is IXP425, Gcc version is 3.3.2, and I've tried to enable/disable those traps, but no help. The aligment is still wrong.
I'm guessing that other place in U-boot that's not a problem since they are not using unaligment 32-bit words, but I am since I try to read 32-bit word from struct and struct isn't aligment correctly. I've tried to make it packed, but that didn't help. I got the pointer to that struct from U-boot function so there aren't much to do unless I want to change whole U-boot.
Has anyone else have similar problem and how did you solve it now that it seems that the aligment trap option of the gcc doesn't do anything. I've tried to compile new version of gcc, but so far I've only managed compiled succesfully binutils.
Thanks.
