按照仓库内文档安装蓝牙支持后，蓝牙并不能正常驱动 发现#1513 有同样问题，并且无法运行rtk_hciattach程序，提示 -bash: /usr/bin/rtk_hciattach: No such file or directory 接着

root@armbian:~# file /usr/bin/rtk_hciattach 
/usr/bin/rtk_hciattach: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=cd4b77500233e9a17c422c673c8984451b72e99b, not stripped

发现是个32位程序，然后到lib目录看，没有/lib/ld-linux-armhf.so.3这个文件 然后apt-get install libc6-armhf-cross， 安装后的文件默认就在/usr/arm-linux-gnueaibhf/lib，该文件夹内有ld-linux-armhf.so.3 在lib目录下将其软链接 root@armbian:/lib# ln -s /usr/arm-linux-gnueabihf/lib/ld-linux-armhf.so.3 /lib/ld-linux-armhf.so.3 再次运行 root@armbian:/lib# /usr/bin/rtk_hciattach /usr/bin/rtk_hciattach: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory 提示缺少libc.so.6，刚好系统的lib目录里没有这个，但是/usr/arm-linux-gnueaibhf/lib这有，并且这个文件也是个链接 通过ls -l libc.so.6，发现该文件夹内的libc.so.6是链接到libc-2.31.so

root@armbian:/usr/arm-linux-gnueabihf/lib# ls -l libc.so.6 
lrwxrwxrwx 1 root root 12 Mar  3  2021 libc.so.6 -> libc-2.31.so

因此可以 ln -s /usr/arm-linux-gnueabihf/lib/libc.so.6 /lib/libc.so.6或者 ln -s /usr/arm-linux-gnueabihf/lib/libc-2.31.so /lib/libc.so.6

经过如此操作，rtk_hciattach可以运行了.

命令行运行/usr/bin/rtk_hciattach -n -s 115200 ttyAML1 rtk_h5 & 后

root@armbian:~# /usr/bin/rtk_hciattach -n -s 115200 ttyAML1 rtk_h5 &

Realtek Bluetooth ERROR: Can't access firmware /lib/firmware/rtlbt/rtl8761a_fw, No such file or directory
Realtek Bluetooth ERROR: Get BT firmware error

最后几行提示找不到/lib/firmware/rtlbt/rtl8761a_config和/lib/firmware/rtlbt/rtl8761a_fw 我直接把/lib/firmware/rtlbt/目录下文件名进行修改。 rtl8761b_config改成rtl8761a_config，rtl8761b_fw改成rtl8761a_fw 结果就tm的驱动了，hciconfig也有输出

我不知道是是哪个文件设定了使用rtl8761a_fw和rtl8761a_config，大佬能否改回之前的？或者固件里面用rtl8761a这个名字？ 可以将相应的解释器ld-linux-armhf.so.3和libc.so.6内置在固件

安装在usr/arm-linux-gnueaibhf/lib，文件夹内有ld-linux-armhf.so.3 小白一个，请问这个如何操作？

默认就在这个文件夹里面，不需要操作什么。继续后续的软链接操作就行

上面文章链接里写的名字是rtl8761b_config，所以我在 https://github.com/ophub/firmware/commit/352e08648d3bdd39feaaba68064cf7629986b847 里添加了一样的名字。你测试叫a，可以是芯片不同但可以共用一个驱动，那就再加一个a吧，这样ab两个都兼顾了。

嗯嗯，一番操作后，有蓝牙了

说来也奇怪，同样的盒子，在之前版本的固件中（大概半年内吧），按照网上一些论坛上传的b驱动，传上去确实是可以用的，我还用了好久的homeassistant蓝牙连接设备。这两天重刷新版就发现不对劲
