Hi, Ryan

Your advice very worked. Thank u.
By the way, I dumped 'libc.a', but I could not find __aeabi_memcpy. So there is no library consisted __aeabi_memcpy in 
qnx's tool chain, right?   

BR.
Jerry.

You'll have to add a wrapper function like the following to your code;

void __aeabi_memcpy (void *dest, const void *src, size_t n) {
    memcpy (dest, src, n);
}

Note: your library will only be ABI compatible with the 'armle-v7' 
variant and you cannot use it with the 'armle' variant.
