硬件：T5000 + 自研载板 + AX210模块（wifi+bluetooth）

软件：R39.2.0 + 定制内核 + 解压AX210对应微码文件

问题现象：开机后，lsusb可见蓝牙设备，hciconfig可见hci0；执行命令hciconfig hci0 up失败，然后hci0就消失了。请帮忙指点一下如何处理？系统usb日志如下：

Are you able to put this AX210 to NV devkit USB port and see if you could reproduce on NV devkit too?

AX210在Thor Devkit上工作正常。bluetooth可以正常打开并连接蓝牙设备。

补充一些信息。M2E接口上的I2S，LED和SDIO引脚（PCM\_XX\_I2S\_XX，LEDx，SDIO\_XX ）都没有接，就是悬空的。这个有关系吗？

Which port are you using on Thor devkit? Is that also M.2 key E?

是的。在Thor devkit上，AX210也是接在M.2 key E接口上的，替换原装的wifi+bt模块。

我们的自研载板这部分电路，也是参照devkit设计的。

It has nothing to do with SDIO pin. If issue could not reproduce on NV devkit, please check signal integrity.

问题解决了，根源在于加载的微码文件错误。AX210的蓝牙应该用ibt-0041-0041.sfi，误用了ibt-0040-0041.sfi。更正文件后打开AX210蓝牙成功。
