各位大佬,我手头有个RK3568的开发板,但是镜像比较简单,库里面缺好多东西,安装过程中发现缺失systemd,然后就开始使用buildroot折腾一下,现在有个问题,在编译到libusb时,出现
2022-11-14T14:43:19 checking for library containing clock_gettime... none required
2022-11-14T14:43:19 checking libudev.h usability... no
2022-11-14T14:43:19 checking libudev.h presence... no
2022-11-14T14:43:19 checking for libudev.h... no
2022-11-14T14:43:19 configure: error: "udev support requested but libudev not installed"
然后我检查了配置,找到libgudev,发现已经选中。不知道各位有什么方案或者思路吗?
硬件上要把GD32的四个串口引脚断开, 从AP6210B的串口飞线, 接USB的FT232R, 挂载到VMWARE+UBUNTU上
执行Broadcom 蓝牙初始化程序:

这个最后一张图片不是手机串口助手吗??
