环境描述：从i.MX6到TI蓝牙设备CC2640r2 通过UART3进行数据通讯，CC2640r2f已经烧录固件host test app（simplelink_cc2640r2_sdk_3_40_00_10），在/lib/fireware/下也有固件TIInit_6.12.26.bts，已经确定串口通讯正常，bluez移植成功，现进行如下操作
root@DESBase:/# hciconfig hci0 up
Can't get device info: No such device
/root@DESBase:/# hciattach -t 30 -s 115200 /dev/ttymxc2 texas 3000000 flow
Initialization timed out.
请教大神：
1、蓝牙模块为什么没有被识别到
2、需要进行哪方面的修改
系统开机有关蓝牙打印信息如下
