建议使用ubuntu16.04 64位，并将wiki中提到的依赖包全部安装完后再编译，一般不会出什么问题

@feige 你的操作系统是什么版本

18.04?

硬件对应链接关系看一楼。
需要注意的是，除了CLK，其他线均需添加10K上拉电阻（SDIO通讯标准要求）。
软件找到这个文件：

按照如下patch修改：

LAN-LED的引脚应该是还处于PHY模式，而不是GPIO模式。
执行 ethmode w 或 ethmode l 命令后就恢复到gpio了

这是哪个板子？

因为/dev/下的文件并不能随便读写。grep需要排除该目录。

V833 has 2 i2s , Where i2s1 has two data lane.

four i2s mic ? 2L +2R ?

@jonsmirl
The 8080 interface type does not have a universal wire sequence connector, unlike RGB 40Pins.
I am looking for mipi-csi (2-lane) whether the line sequence is universal.
In addition, if the core board is equipped with FPC24, it may limit the assembly.

ARMv7: 800MHz
DRAM: 64MB
NPU: 200Gops, Conv, Activation, Pooling, BN, LRN
100Mbps eth and 150Mbps WiFi
Storage: SPI flash / SD card
MIPI-CSI: 2-lane max 5M pixel
LCD: easy drive 5-inch LCD
USB: HS OTG
more~~

@jonsmirl "APP" that based chrome V8?

@jonsmirl I have not received this price
In addition, the 512MB will not be launched soon

@jonsmirl 在 Sochip X3 资料汇总 中说：

@jonsmirl https://github.com/aodzip/cedar may help you

@jonsmirl 在 Sochip X3 资料汇总 中说：

You may ask, why does Allwinner keep their h.264 encode/decode source closed. It is not because they have invented something new. It is almost assuredly because they have violated numerous patents with their h.264 implementation and they don't want to get sued. By keeping the source closed it is very difficult to know for sure if they have violated a patent or not.

Very reasonable, I also think that is the reason!

This is also a headache for me, because now allwinner does n’t like the open source community!

As far as I know, the kernel of tinalinux should have been updated to 4.9 for new chip of sochip, like V831/v833

Thanks, I understand
I will try to let the hardware support the follow-up design.
For the software part, I will refer to the R328 SDK

@jonsmirl
Is three mics ok? like: mic1 ---- mic2 ---- mic3

In fact r328 or K210 is more suitable for mic array

@jonsmirl https://sns.widora.cn/topic/632/79元的redmi-小爱音响首拆-全志r328方案
two i2s mic
I am using it and it works great

@jonsmirl correct,
In this way, how many mics should be supported at most?
It can directly connect to an analog mic

@jonsmirl It should be public soon, tinalinux , 4.96 GB

@jonsmirl 　It only has one I2S , We can design two I2S MIC

等待添加, 这才是驱动屏幕的完美方案~~

今天, 我发现, V831的LCD和RMII是可以分开的!
等收到板子后, 我看看如何搞定它

V831_QFN88_PINOUT_V0_1.xls

7629目前联发科还没开放购买, 我估计今年年底时候该方案会成熟起来.
放弃mips, 迎接arm A7

@rhyttr
目前从代理那边得知, 以后打算用MT7629作为7620,7621,7688的(wifi5,wifi4)替代. 7629是双核ARM 路由器SOC, 3*3双频 1900M带宽, 性能有点过剩, 但确实是可以给wifi5画上要给完美的句号.
