Hi all, Iam porting a c application to arm7tdmi which contains malloc and calloc functions.I want to know wheter is there any other method to allocate memory other than using malloc for eg; returning a fixed memory address using a dummy function instead of caling malloc. Regards Suresh

You can create your own version of malloc() and place that code in the link list before the standard libraries, then your version will simply override the standard implementation. You would also need to override free(), even if it were just a dummy function. I did exactly this for example when I needed to integrate zlib decompression in a bootloader that could not use the standard library at all. zlib called malloc exactly once with a predictable size, so I just dummied a malloc(). All that said, why can you not simply use the standard malloc() function (you only have to implement __sbrk or sbrk_r to make it work, examples are provided with the WinARM tools in the syscalls.c file)
