2010-05-14 17:28:41 Possible problem using a float on a 522
Reggy Perrin (UNITED STATES)
We have working code on a BF526 board that we are porting to a 522 board. Hardware is almost identical. However, our program *appears* (I'm not ready to say definitively) to be bailing when we pass a float to a function.
In reading the wiki, I've added "-mfast-fp" to the bfin-linux-uclibc-g++ command, but that doesn't seem to change anything.
In looking through the kernel and library settings (from make menuconfig), I don't see any options that need to be set when building the kernel and libraries.
Am I missing something?

all Blackfin cores are exactly the same when it comes to the ISA and the userspace code generated. perhaps it's more a matter of using something uninitialized and it just happens to work on the BF526 board.
