WhyCan Forum(哇酷开发者社区)

适用于启明云端的SSD201,SSD202核心板，引出了双USB接口，网口，TF卡接口，调试串口通过CH340G转micro USB引出，剩下两个串口通过4pinXH2.0插座引出，液晶屏引出50pin标准RGB接口，引出电阻触摸屏接口，板子可以配套淘宝上2元一个的PLC工控盒壳体哦，
，另外板子大小控制在10*10以内，可以薅嘉立创5元羊毛哦，RTC部份没画好，暂时没时间改，这个月我的薅羊毛机会也用完了，等下个月出实物了，这里提前分享一下。

有需要的大佬可以看看

电池要到-40摄氏度比较难，一般-40摄氏度的时候电池很难向外供电。

KingJin 说：

用海华的pin2pin兼容

请教具体是什么型号呢?

aozima 说：

我这边是在WIFI SOC中写个固件，然后更新驱动程序。不过研发成本比较高。

ESP8266/ESP32?

核心板出了吗

LCD验证OK了

今天是冬至，大家节日快乐。
自己上手包了几碗饺子，刚刚折腾完。
试了下降低DDR频率，果然可以很稳定的启动
https://whycan.com/files/members/5522/035.png
这是正常启动的样子

恭喜哇, 这是正常操作, 中科世为的A33板子一样DDR要降频才能启动,达不到主线uboot的默认配置速度.

恩，我决定再优化一波，毕竟一个1000多M的DDR，跑出个两三百M,还是有点丢人了
目前打算是一个邮票孔+一个金手指的底板，这样就可以到处插了

芯片到手
大概算了下
打板30,5片
全志H3四片，72
DDR买了11片，80
EMMC两片，40
其它缺的料，合计是63
总计是285

wlcccccc 说：

板子已入手,画块底板玩一下.看文档里是有视频软编码的. 最好买大内存的测试

好像这个月 卖家25号就会有底板卖，主板+底板才100多，我原来也是准备自己搞底板，看有得买就不搞了

刚才问了一下 现在他们也需要钱NDA了. mmp

是啊，主要做了 AP 测试，MT7601u / RTL8818CUS 模块出现的问题是一样的。刚重新用 19.07 源码编译了，下午看看。。

Iron 说：

可能还是驱动问题，感觉坑越来越深。。。十一全在搬家了，东西都找不到了，感觉要弃坑了。

别啊，好不容易找到个一起玩V3S的OP的，我这个就是用的自带的MT7601u驱动，一开始报的信息和你截出来的一模一样，无线里面80211bgn没有信号强度，显示设备未激活，但是能搜到其他热点。后来把master禁用掉就好了。

你是要当AP热点？

你需要外接32K有源信号，内部的不OK

sy373466062 说：

LPO这个接地了，使用的是内部32K clk

你的LPO管脚是否提供了32.768Khz的时钟？这个非常重要

方便飞线的话，可以淘宝买个lan8720模块怼上去看疗效。

R19,R20,R10,R24四个49.9的上拉电阻去掉试一试。

画的板子 启动不了了  后面边学边搞吧 
tf卡插上CMD一直是0V   emmc的CMD一直是3.3V
怀疑系统从emmc启动  可是里面没系统  估计是电路哪块有问题 
我再慢慢排查吧

下面是文件 直接下载即可
share.zip

89元的链接呢

这样问题就不大了

前几天找了一下这款BeagleBone Black开发板，找着找着找到这玩意，买了2块回来，一块70元（带电源、原理图、补焊了USB），一块25元（缺usb外围原件）

CPU：AM3352
内存：256M
ROM： 256M NAND
百兆网口

跟中国版BeagleBone Black有什么区别？
1、阉割HDMI，保留RGB；
2、eMMC改为NAND，GPMC挂着NAND，GPMC挂并口设备爽啊！

我的用处：GPMC接口挂NAND和2片CH438 8串口芯片，一共16串口。
目标：
刷回原来的uboot以及内核，官方的SDK
挂上2片ch438，实现外挂16串口。

Touchgfx designer能跨平台就好了，lib库既然做了linux版，macOS也顺带能编译一份出来就更好了。

底部电源画错了，不过好在大神的帮助下改了线，能用TF卡启动了。
