Re: Case with built-in 4-port hub?

Erm, the new raspberry Pi model B+ has 4x USB ports ;) http://www.raspberrypi.org/introducing-raspberry-pi-model-b-plus/ So it does, but I don't have one of those. I have five older Pi's I'm looking to put to good use, however. :) but also take a look at this "naked" USB hub that has the same form ...

Re: Bare SBC (no OS, just your program)

For bare-metal coding, I think Alex Chadwell's tutorials may be very helpful.

Re: Haiku OS on the Raspberry Pi?

Re: Debian with FP operations (but softfloat ABI)?

If you actually want to use VFP instructions with the soft-float ABI, just compile on Debian armel with: gcc -march=armv6 -mfpu=vfp -mfloat-abi=softfp Right. I understand anyone can do this for C code they're compiling. My question is whether the libraries (and apps) that come already compiled on D...

Debian with FP operations (but softfloat ABI)?

Please forgive me if this has been discussed before — but I don't think it has, quite. Early in the branch that has come to be known as Raspbian, there were binaries compiled with hardware floating-point operations, but still using the soft-float ABI. (It was discussed here .) Then, of course, it wa...

OK, thank you for all the responses. In reality, no matter how many +numbers we give the idea, I doubt a HF version of mono is going to happen.

Re: New wiki page on C#

The actual software that is directly affected by the ABI choice is really not that substantial. Its only an issue that compilers (which a JIT is) must deal with. The larger issue with software compatibility is the choice of processor in Raspberry Pi (armv6 vs armv7) and has nothing to do with Andro...

How would that work ? Do you have any link which shows how iOS and Android do this ? (i.e. being "softfloat" and still profit from hardware floating point ) ? Well it appears that very early in the Raspbian project (before it was even called such), there were binaries built exactly this way. You ca...

Linux distro with softfloat ABI and hardware FP?

It appears to be possible to make a distro that uses hardware floating-point instructions, yet uses the soft float ABI. This makes it compatible with JIT compilers, like the Mono and Java runtimes, that assume such an ABI. Indeed, when Raspian was in its infancy, they ran into binaries already built...

Raspbian is highly recommended for beginners which doesn't mean it's substandard just because it's recommended for beginners.

Re: can Occidentalis v0.2 run .exe file?

One thing to note: Mono also produces .exe files, and these can (sometimes) be run on any system with a Mono runtime. It depends on how the file was built, and what other libraries it's using. Just by seeing somefile.exe, you can't tell; you should talk to whoever developed it (or look for docs). Of...
