Of course it works. There is even the same from the OE environment -and I
mean : from the official repo - , here is set for my angstrom-SDK :
export CC=arm-angstrom-linux-gnueabi-gcc -march=armv7-a -mthumb-interwork
-mfloat-abi=hard -mfpu=neon -mtune=cortex-a8
Interesting.Nevertheless,the only reference to the fp operation context
switch cost I've found is related to the VFP which we don't use with the
Sitara under Angstrom.
For some eventual interested people :
In addition to saving and restoring integer registers, the kernel may also
need to
I think that it can be -at worst -ambiguous, not so wrong: let me resay it :
Nevertheless,the only reference to the fp operation context switch cost
I've found is related to the VFP which we don't use ONLY with the Sitara
under Angstrom as we are talking about *hardfloat *and *softfloat *,
Finally it's become darker for me.
Robert, did you mean that Angstrom distribution use hard float but not the
armhf that we have in ubuntu ? This is why I can't run software compiled
with the ubuntu arm-linux-gnueabihf- tool chain ?
In this case I should better use the Android toolchain (even

The computation may be done either by floating-point hardware or in
software ( based on integer arithmetic ).
Doing it in hardware is much faster, but many microcontrollers don't have
floating-point hardware like the Sitara here. In that case you may either
avoid using floating point (usually the
As I think this a sane question (ie : everyone should ask himself/herself
this ) I answer you that :
- the BBB is based on the AM335x
- This last is itself is based on Cortex A8
Therefore if you dig into the A8 arm documentation
