通过串口查看3A5000开机引导CLFS获取的信息

杜比

通过串口获取开机引导信息的方法

使用一根串口线缆，两边各带有一个母头。
一端母头接主板上的串行接口DB9插座
另一端母头接另外一台电脑或者笔记本，Windows环境下可以使用DWN等软件
配置CLFS的grub.cfg文件，

具体配置

// console=ttyS0,115200 loglevel=8 
// 是后加入的配置，配置了启用串口输出和通讯速率，也配置了启动信息输出等级
menuentry 'My GNU/Linux System for LoongArch64' {
echo 'Loading Linux Kernel ...'
linux /vmlinux console=ttyS0,115200 loglevel=8 root=/dev/sda3 rootdelay=5 rw 
initrd /acpi-initrd
boot
}

备注

使用板载7A1000所集成的显卡，可以获得更好的兼容性，实测景嘉微的7201不兼容
grub.cfg配置信息，需要酌情进行修改 root=/dev/sda3 字段，系统多块硬盘会导致驱动分配的设备名发生变化，可是试试sda,sdb,sdc等，后面的数字不用更改，3表示的是第三个分区。

我用咸鱼购买的主板测试了一下，可以抓取到主板信息和 grub 引导信息。 https://github.com/archlinux-loongarch64/docs/blob/master/serial-port.md

测试串口线

安装串口线驱动，如果需要的话。
短接端口
- (TTL) 用一个杜邦线，将 ttl 的 TxD 和 RxD 短接。
- (DB9) 百度找到 db9 母口的针脚定义图，我们发现， 2 TxD 3 RxD。用一根导线插入 2，3 进行短接。
下载打开串口测试工具，我这里选择 putty。
在 putty 中输入信息看是否能输入信息，如果能输入信息，说明 ttl 设备正常。
如果不能输入信息，调整 Data bits Stop bits Parity Flow control 参数，直到能够正常输入信息。
如果还是不行，尝试换一个串口测试工具，或者换一个设备。

接线方法

ttl

ttl RxD => 主板 TxD

ttl TxD => 主板 RxD

ttl GND => 主板 GND
db9 母口接龙芯主板，usb 接另外一台电脑

用 ttl 获取主板调试信息

打开 putty，设置 serial /dev/ttyUSB0 speed 115200 开始抓包，不同主板使用的频率可能不同，如果出现乱码可以优先调整这个参数。
开机，抓取日志信息。

测试 ttl/db9 对应 /dev/tty?

接线，打开 putty
进入 clfs 系统执行 ls /dev/ttyS*，显示的 tty设备挨个按照下面流程测试，以 /dev/ttyS0 为例
1. stty -F /dev/ttyS0 speed 115200 设置串口频率为115200，这里设置的串口频率应该和 putty 中设置的相同。
2. echo "abc" > /dev/ttyS0 如果 putty 中显示了 "abc" 则说明串口是 ttyS0，这个数据为下面 grub 中配置做准备。
