Well from what I was able to find, it seems ARMv7 systems can only run BE8 mode, while ARMv5 and older had BE32 mode, and ARMv6 had both options. Qemu seems to support BE8 mode when emulating ARMv7 (at least if you have a recent enough version). -- Len Sorensen -- ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto

Does QEMU support NEON? Andreas -- ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto

Most ARM systems can run in both big-endian and little-endian modes. Somewhere early during boot this choice is being made. Having said that, since big-endian machines are getting rare, there's very little support for big-endian ARM systems. Most (if not all) boards can run big-endian, but software support is usually lacking, in particular in the bootloader parts where this matters. If it's just for testing some software, maybe you can use a QEMU machine?

[yocto] Big endian ARM machine with NEON wanted
Hi, Does anybody know a big endian and common machine supporting NEON? I would need one for testing my port of portaudio. Thanks in advance Andreas -- ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
