如题，在Bluetoothctl的终端交互中提示No default controller available。
这是个什么原因呢

已经解决了
wlan_regon是这个引脚我给他配置成了低电平有效导致的

大佬是否解决了 我也遇到这样的问题

现在打印信息是这样了

@shuaige 在 t113i启动异常 中说：

@yyh5961 之前在其他平台遇到过，是编译出来的kernel镜像有问题

对的 是我改动的地方错了，我是在device/product/configs/xxx/这个下面修改的，然后实际上得在xxx/buildroot/这下面修改才有效果 这下面优先级更高

老哥们 为什么这个这个sdio被移除了啊

@lipeitong 问题解决了吗 大佬

回复: 全志芯片Tina Linux 修改 UART 引脚、UART端口

照这个帖子修改了，现在板子上电后只打印这么点内容，uboot也只有在烧写的时候才打印，内核都没有打印信息，有没有大哥知道这是什么情况呢

你这最后咋改的
