我尝试加载Linux驱动程序,并收到以下消息:
# modprobe hci_uart
hci_uart: Unknown symbol hci_free_dev (err 0)

modprobe: can't load module hci_uart (kernel/drivers/bluetooth/bluetooth_uart_driver/hci_uart.ko): unknown symbol in module, or unknown parameter
该模块已在linux-menuconfig
中检入(我使用buildroot
),我试图加载其他Linux驱动程序,但未收到此消息。
任何想法。 非常感谢。

我发现有麻烦的依赖项,因此从linux-menuconfig我添加了所需的依赖项。我检查了makefile,以了解必须添加哪个文件。
