Hi, On 23/12/16 12:50, Icenowy Zheng wrote: Based on the Allwinner H5 datasheet and the pinctrl driver of the backward-compatible H3 this introduces the pin multiplex assignments for. Allwinner A100 should be for mid-range tablets, and potentially offer an update path to Allwinner A64 designs. Allwinner A200 specifications: CPU – big.LITTLE design (AFAIK, only the second such processor from the company after Allwinner A80 ). Based on the Allwinner A64 user manual and on the previous sunxi pinctrl drivers this introduces the pin multiplex assignments for the ARMv8 Allwinner A64 SoC. Port A is apparently used for the fixed function DRAM controller, so the ports start at B here (the manual mentions 'n from 1 to 7', so not starting at 0).
This page needs to be properly filled according to the New Device Howto and the New Device Page guide.
This is a limited edition product verification board that is used here for the purpose of mainline support of the A83T SoC.

On the front of the board, the following is printed:
The PCB has the following silkscreened on it:
These markings do not have specific significance to the A83T since this is a product verification board.
Current status
There is ongoing discussion at https://groups.google.com/forum/#!topic/linux-sunxi/_woM2vJmcuc regarding the mainline support of the SoC in this board.

BSP
The repository at https://github.com/allwinner-zh/bootloader contains
- BSP for the A83T, https://github.com/allwinner-zh/bootloader/tree/master/basic_loader/bsp/bsp_for_a83
Manual build
- For building U-Boot, use the MANUFACTURER_DEVICE target.
- The .fex file can be found in sunxi-boards as MANUFACTURER_DEVICE.fex
Everything else is the same as the manual build howto.

Mainline U-Boot
For building mainline U-Boot, use the 'h8_homlet_v2_defconfig' target.
The reference source code from Allwinner is at https://github.com/allwinner-zh/bootloader contains

Mainline kernel
Basic support is available in mainline kernel for A83T.
Use sun8i-a83t-allwinner-h8homlet-v2.dtb device-tree tree binary.
There is a 3.4 source tree for the A83T at https://github.com/allwinner-zh/linux-3.4-sunxi/tree/A83T Revit architecture 2017 with crack.
The following table is a comparison of the A83T SoC to other SoCs from the A-series.
| Module | Description |
|---|---|
| CPU | Cortex-A7 MP4 in 2 clusters, the MCPM is more likely as the A80 |
| CCI400 | It's same as the A80 |
| DRAMM | It's more likely as the A80 |
