关于Linux 内核配置:
有线网卡驱动代码已经合入主线了,并不需要对代码进行修改,只需要配置内核即可。
1. Linux 6.10.3中没有“licheepi_zero_defconfig”,需要先从 Linux 5.2.x 中拷贝过来。
2. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- licheepi_zero_defconfig
3. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig 做如下修改:

关于Linux 设备树配置:
Linux 6.10.3中存在“sun8i-v3s-licheepi-zero.dts”设备树文件,只需要开启 “emac” 即可。
编译 & 烧录, 然后就可以愉快的上网了。

有可能是网线不好或者硬件问题

网线确定没有问题,用在其他设备或者电脑上都稳如老狗, 其他的话,硬件参考的荔枝派的电路图,照理说不应该有问题,布线用的PADS,tx和rx都是设置的差分布线,也没有大的转角,设计布线上应该问题也不大,电源用sy8079,可以输出2A电流,而且以前用在海思上也得到了验证,也不存在供电不足的情况,晕菜了

检查下 EPHY-RTX 引脚的 电阻? 虽然不知道他是干啥的,但是各种开发板上都这样接的,我也这样搞上去了; 还有SZQ引脚,同样不知道是干啥的!
