I didn't think I COULD build for aarch64 on the Pi2.... that = will work? Which type of RPi2? There is more than one. I've access to: a RPi2B v1.1 (Cortex-A7, so armv7 only) and: a RPi2B v1.2 (Cortex-A72, so aarch64 but also capable of armv7 use) RPi3B variants are also Cortex-A72 based, so aarch64, but are also armv7 capable. (I've access to a RPi3B as well.) Basically a RPi2B v1.2 is a variant of the RPi3B. As of the RPi4B's the RPi* folks quit trying to allow booting as armv7. But in FreeBSD you can chroot into a armv7 world on a RPi4B, for example. (Also on: RPi3B or RPi2B v1.2 booted as aarch64.) You can build armv7 ports on a RPi4B via poudriere, no quemu involved. The same for RPi3B booted as aarch64. The same for RPi2B v1.2 booted as aarch64. =3D=3D=3D Mark Millard marklmi at yahoo.com
