Hi, I'm trying to find a way to do double precision multiplication, giving that the inputs to the multiplication are double precision also. I know how to do single multiplies rn=ra*rb; no issue, only 32bit * 32bit => 32 bit. mrf=rn*rb; also, no issue, only 32bit * 32b8t => 80bit But for this one multiple, I need to do 64bit * 64 bit =>64bit, and

Hi, Peculiar situation arising. Aperiodically, when running the full product code, I get reset into the HW 256 byte boot loader. I know for a fact that it is the HW boot loader because it first loads a product specific boot loader I wrote, that has a given running mode that is lost as soon as it loads any of the product codes. Remember, I'm the one that re-
