Looking at this[1] I wonder what this is about: Linux does not currently support floating point hardware so you need to say Y here even if your machine has an FPA or floating point co-processor podule. I needed to enable CONFIG_FPE_NWFPE to make the debian binaries work. < CONFIG_FPE_NWFPE=y > # CONFIG_FPE_NWFPE is not set I wonder why this wasn't necessary for the neuros userland.. Maybe because it's uclibc? So, does the davinci Arm have float support? It doesn't look like it (no `fpu' in /proc/cpuinfo). From here[4] no mention of FPU either, only fixed point DSP extensions (single cycle mac and 16x32 bit multiplier). It uses the ARMv5TEJ instruction set[5]. Makes sense, since the DSP is also fixed point. Are there any Arm chips with float support?
