shell 信息可以出现在 kmsg 里面是什么原理？

还有他的WIFI网卡，既可以自己做热点，又可以同时连接别的热点，不知道怎么做到的。

目前还不能通过WIFI桥接上网，虽然在串口终端ping qq.com 正常。

以前的buildroot可以构建arm linux下的gcc，现在新版本已经删除了。

如果把 debian 怼上去，可以通过apt安装gcc。

TSC2007 I2C触摸驱动有个地方没搞明白，
为什么IRQ引脚和GPIO检测PEN引脚状态可以是同一个，
这样在 IRQ/GPIO 两种复用之间要来回切换吗？
可是驱动代码里面并没有出现这种切换。

多谢大佬指点，哪里可以设置关闭LCD，是在uboot设置里面，还是需要改代码？
哇酷小二说：
有没有可能PD10/11 的 UART1复用被LCD初始化覆盖了?

如果修改设备树没用的话， make menuconfig 禁用这个 CONFIG_VIDEO_SUNXI

弄了一下午,终于解决这个编译错误了

https://git.busybox.net/buildroot/commit/?id=d3f576d2f37a05275c0d25f855dc24935ff5de5c

修改: ./output/build/mesa3d-19.3.4/src/mesa/drivers/dri/meson.build

libmegadriver_stub, libdricommon, libglapi,

改为:
libdricommon, libmegadriver_stub, libglapi,

即交换编译顺序.

第一，不能直接用ttl电平，不然这么多很容易出问题。
第二，modbus通讯比较慢，即使提高波特率也会存在3.5char的问题。

请教应该使用什么电平呢,用什么电平转换芯片?
3.5char是什么问题呢?

估计解压姿势错误，要在Linux(Ubuntu)用tar 解压, 这样才能保证软链接和执行属性没问题.

把卡插入系统看下文件出了什么问题。

拉轰的脚踏车说：

用 devmem 去读 PB_CFG0 寄存器

看是否处于中断复用？

查了一下, PB_CFG0 地址应该是 0x01C20824

insmod hello.ko 之前:
devmem 0x01C20824: 0x77477733

insmod hello.ko 之后:
devmem 0x01C20824: 0x77447733

看来这个PB4的复用应该没有错误，只能检查别的问题了。

看来还是去 Icenowy 的仓库围观一下:

还有展开的结果应该是PINCTRL_PIN(PB_BASE + 4, “PB4”)

看起来应该是这样了，感谢大佬。

ubuntu · VMWare/Linux/Ubuntu/Fedora/CentOS/U-BOOT

https://github.com/torvalds/linux/blob/master/drivers/pinctrl/sunxi/pinctrl-sunxi.h#L32

#define SUNXI_PINCTRL_PIN(bank, pin)		\
	PINCTRL_PIN(P ## bank ## _BASE + (pin), "P" #bank #pin)

所以这个宏函数：
SUNXI_PINCTRL_PIN(B, 4)

展开应该是:
PINCTRL_PIN(PB_BASE + 4, PB4)

那么问题来了，请教一个#, 和两个#有什么区别呢？

v3s如何？看着最近在涨价啊

估计疫情导致供应链紧张吧，后面应该慢慢缓解，目前好几家芯片都开始炒作涨价了。

谢谢！已经解决。

请问是如何解决的？

ubuntu · 全志 SOC

这个文件 include/configs/suniv.h 还得加上:

#define CONFIG_CONS_INDEX 1 //UART0
#define CONFIG_CONS_INDEX 2 //UART1
#define CONFIG_CONS_INDEX 3 //UART2

已经解决了，就是因为分区的原因，之前分区的时候将GPT 搞坏了，重新全部分区之后解决的（diskgenius重新格式化）

原来如此!

别怕，有可能一年后价格更便宜，而已云服务器数据迁移很容易。

到时候再建一个新账号，

反正阿里云的新账号又不绑定手机号码，手机号只用安全验证只用，一个手机号可以注册多个新账号。

克隆u-boot并恢复到 v2017.11 的 tag:

git clone https://github.com/u-boot/u-boot

8. mobaxterm 登陆进去，克隆一个Linux:

mkdir ~/A33/
cd ~/A33
git clone https://gitee.com/mirrors/linux

9. 编译A33, 参考 https://whycan.cn/t_3643.html#p33345

#克隆
git clone https://gitee.com/mirrors/linux
cd linux
#默认配置
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make sunxi_defconfig
#手动配置
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make menuconfig
#编译
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j3

下面这两个就是你需要的文件了:

arch/arm/boot/zImage
arch/arm/boot/dts/sun8i-a33-sinlinx-sina33.dtb

69元阿里云服务器购买参考这里: https://whycan.cn/t_3969.html

1. 添加用户: sudo useradd ren

2. 重设ren密码: sudo passwd ren

3. 建立用户目录:

sudo mkdir /home/ren/ -p
sudo mkdir /home/ren/.ssh -p
sudo chown -R ren:ren /home/ren/

4. 生成秘钥: ssh-keygen -t rsa -b 4096 -C "10000@vip.qq.com"
私钥: id_rsa
公钥: id_rsa.pub

5. 公钥拷贝到目录: sudo cp /home/ren/.ssh/id_rsa.pub /home/ren/.ssh/authorized_keys

6. 用私钥 ssh 连接服务器，推荐 mobaxterm:

7. 现在新用户可以为所欲为了。
