Hi,
I am using Yagarto tools for ARM development (AT91SAM7S64). Everything seems to be OK, except that when I use malloc the returned pointer points to
0x00000008 regardless of the amount of bytes that I want to allocate. I have read the newsgroups, but nothign seems to help.I need your advice with my .ld file, in order to know what could be messed / missing and how to fix it. Other suggestions are welcome too.
