Status

ARM is officially a Tier 2 architecture, as the FreeBSD project does not provide official releases or pre-built packages for this platform due to it primarily targeting the embedded arena. However, FreeBSD/ARM is being actively developed and maintained, is well supported, and provides an excellent framework for building ARM-based systems. FreeBSD/arm supports ARMv4 and ARMv5 processors. FreeBSD/armv6 supports ARMv6 and ARMv7 processors, including SMP on the latter.

64-bit ARM support is in progress.

FreeBSD/ARM Hardware Notes

FreeBSD/arm and FreeBSD/armv6 support a large range of ARM CPUs and development boards. Not every peripheral is supported on every CPU or board, though work continues towards this and contributions are always welcome. Conversely, many CPUs and boards not listed may work with only minimal changes needed.

Listing all supported devices on all CPUs and boards is impractical here, however much information can be obtained from the mailing list and archives, the FreeBSD/arm Wiki pages, and also from the Kernel Configuration files

What Needs To Be Done

• SATA support needs to be added for boards currently missing it.
• Other devices, such as watchdog, i2c and bus should be merged from NetBSD.
