Allwinner H6 (sun50iw6p1) SoC features a Quad-Core Cortex-A53 ARM CPU, and a Mali-T720 MP2 GPU from ARM. The Allwinner H6 is an OTT SoC.



Mainline support not started yet due to lack of boards. Xunlong and Pine64 are working on H6 SBCs.

Differences / New features (compared to H5)

High level differences

  • addition of PCIe support
    • single lane PCIe 2.0
    • totally undocumented software interface
  • addition of USB 3.0 host
  • Mali T720 instead of Mali 450
  • DDR4 DRAM support
  • addition of IOMMU
    • though only connected to display controller and video codecs
  • (New?) Audio Hub component

programming model/driver level differences

  • heavily changed memory map (UART0 at 0x05000000, for instance)
    • SRAM locations moved around as well (SRAM A1 at 0x2000 now)
  • bus clock gates and device reset control now grouped by devices and merged into one register (high 16 bits reset, low 16 bits clock gates)
  • DMA controller changed (more than 32 ports, but still limited to 32 bit addresses)
  • no GPIO port A and B
