@yuzukitsuru 我又尝试了cat ,但是不能读。
root@TinaLinux:~# cat /sys/class/net/eth0/speed
cat: read error: Invalid argument

@yuzukitsuru 插拔网线是可以看到，但是运行过程中怎么查那？想看看运行过程中它有没有自动降速之类的？

TinaLinux请教如何查询网卡当前是百兆还是千兆？用ethtool eth0 显示
Settings for eth0:
Link detected: yes
不显示speed等参数，请教一下，还有没有其他办法查询网卡当前是百兆还是千兆？？

@allwinnertech 是的就是想在uboot 中配置好，但是没有成功。

@yuzukitsuru 现在就是logo 显示的有些慢，大约上电4s左右到kernel 启动后才能显示出来。

@yuzukitsuru 您好，我把vi lichee/brandy-2.0/u-boot-2018/configs/sun8iw20p1_defconfig 中的CONFIG_AW_PHY=y 注释掉了。试了一下，还是不行。我看
执行了show_bmp_on_fb

硬件平台r528 ，tina 系统，u-boot-2018。用spi1 驱动一个st7789v的240*240的小屏。
kernel现在已经可以显示logo.但是uboot 阶段一直不显示？请教一下具体怎么配置？
还有请教uboot阶段系统运行开机logo的步骤？现在不知道怎么跟踪，不清楚问题出在那里？
修改了一下内容，还是没有显示：
1、tina-r528/lichee/brandy-2.0/u-boot-2018/include/configs$ vi sun20iw1p1.h
增加了头文件

  #define CONFIG_VIDEO_LOGO
 #define CONFIG_VIDEO_BMP_LOGO

2、tina-r528/device/config/chips/r528/configs/evb1$ vi uboot-board.dts
设备树修改

};

3、tina-r528/lichee/brandy-2.0/u-boot-2018/arch/arm/dts$ vi sun8iw20p1-soc-system.dts
增加SPi1 节点

4、tina-r528/lichee/brandy-2.0/u-boot-2018/drivers/video/sunxi/disp2/disp/lcd$ vi st7789v.c
修改驱动初始化

5、menuconfig 选择st7789v。
