板子焊完一直没有时间调试驱动，目前先把屏幕点亮了。另外原理图奉上a589b620-6361-47c4-a1c4-ae4480327eaf-Schematic_SnialPI_2_2022-10-21.pdf
（个人玩具谨慎使用）。

经过断断续续一个多月的查找资料，参考了芒果大佬、韦东山大佬开源的相关原理图吗，(感谢大佬们的无私奉献)，终于将Snail Pi 2.0 (V1.0点这里)板子画了出来，暂时上个图占个位置（尚未打板验证，先准备仔细检查一下原理图和布线）后续有必要也会开源出来。

汇报一下目前的项目状态，目前已经完成打样，焊接，使用测试镜像跑成功了一半

系统

为什么说跑成功了一半呢，是因为板子的串口使用的是UART3(PB6、PB7)，使用芒果大佬镜像改串口发现无效，还要去研究一下，最后使用了100ASK_T113_Pro开发板 的镜像，顺利进入的内核，但可能是因为本身板子存在差异，最后在内核层挂了，启动日志如下：

慢慢调试吧。

关于硬件

另外硬件部分有个问题，

如图在LCD屏幕背光电路中，使用了两颗1N5819二极管我使用的是SOD-323封装的S4

但是都会出现电压倒灌的问题，不知为啥，后来换了SS14封装的二极管就没问题

开源

对于开源的话会在调试的差不多的时候，至少保证大部分功能没问题的时候放出。

@evler 在 MangoPi Dual T113 主线内核编译记录 中说：

sudo dd if=awboot.bin of=/dev/sdd bs=1024 seek=8
神奇，使用百问网的t113 pro开发板，不管改不改内核设备树里面的 uart接口，都是boot启动不了 内核，明天再排查排查

看看这个，希望能用到

Linux主线适配完毕，基于Linux-6.0.1

那只熟悉的蜗牛回来了

通过Evlers大佬的帖子：
https://bbs.aw-ol.com/topic/2338/mangopi-dual-t113-主线内核编译记录
成功移植了awboot

原版使用uart5，我使用uart3 ,需要修改一下代码：

当然除此之外还需要修改一下设备树，增加uart3的相关节点。

主线，主线

我这使用的是TF卡启动，所以不太清楚SPI nor怎么搞

@ftwtwzy fe8.1的hub芯片有驱动么？

好像不需要驱动

@ftwtwzy 将R3改为0R估计就不会有倒灌问题了。

我换成 B5819w/SL 的二极管就没问题

板子焊完一直没有时间调试驱动，目前先把屏幕点亮了。另外原理图奉上a589b620-6361-47c4-a1c4-ae4480327eaf-Schematic_SnialPI_2_2022-10-21.pdf
