板子上使用xr819,v3s 与 xr819的连接关系为：
PE23 - reset
PE24 - WIRQ
驱动使用 https://github.com/fifteenhex/xradio ，也成功编好了，到v3s insmod xr819.ko
然后在ifconfig -a 里并没有新增加一个网卡
目前有点束手无策，不知道从哪里下手
请大佬帮忙看看可能是什么地方有问题

首先确认硬件有没有问题?
如果硬件没问题, 看下 dts 里面 该 sdc 有没有启用?
硬件问题不太好确认是不是OK的，因为感觉外围电路比较简单就直接打板了，手头也没有成品的xr819模块来对比，头疼
原理图：

dts是启用的，启动日志下看到有
[ 1.282352] sunxi-mmc 1c10000.mmc: allocated mmc-pwrseq
[ 1.415797] sunxi-mmc 1c10000.mmc: base:0xc498b000 irq:24离线
仔细检查了一下，发现使用主板使用该模块的原理图符号画错了，导致信号线连接错误了，令人汗颜，只能另外打板测试了

硬件问题确认方法：
1. 万用表测量供电是否正常
2.wifi都有时钟的，需要看看时钟是否正常，和软件配置的时钟是否一致
3. 如果要测试连接，可以看看接口上是否有对应的波形。
谢谢，学习了
