Hi, I got this compilation error in SDK 2.0 : (0): error : Function __mul_32 not found I use hash_48() in my micro C code. The parameters of hash_48 are sram xfer registers. And I declared and used other sram xfer registers too. Is the error because of running out of sram xfer registers ? Thanks, -- Luo, Yan yluo@cs.ucr.edu Dept. of CS, Univ. of California Riverside, CA 92507, USA http://www.cs.ucr.edu/~yluo
