Having received the big black box on Monday, I've had time to do a little playing, and the first thing I came across was finding that standard debian-compiled arm binaries didn't run.
I've investigated this, and its due to the FP emulator not being built into the kernel. While the openmoko stuff is compiled using software float, which gives better performance, the debian distro is still using the ARM floating point instructions, which need emulating on pretty much all ARM chips. Looking at the linux package, in defconfig-2.6.21.6-fic-gta01 we see: # CONFIG_FPE_NWFPE is not set CONFIG_FPE_FASTFPE=y But looking at the current kernel sources, as far as I can see there is no FASTFPE code at all present in the kernel tree - its been completely removed! I recompiled the kernel with CONFIG_FPE_NWFPE=y, and it makes it 15K bigger, but now all the debian binaries run quite happily, and I've reformatted a micro-sd with ext2 and put a debian chroot onto it. Might I suggest that this change would be well worth while putting into the standard package, since its extremely useful to be able to just grab debian binaries to experiment with libraries and toolkits. If they end up being used in the final distro, we can of course recompile them with the openmoko toolchain to use the soft float and the standard C library. -- [EMAIL PROTECTED]
