Hello,

I compiled source of bluetooth drivers for Marvell SDIO bluetooth module. While inserting the module am getting some errors.I am using Linux BSP 2.6.35

root@freescale /home/user$ insmod mbt8xxx.ko

BT FW is active(0)

BT: FW already downloaded!

root@freescale /home/user$ insmod bt8xxx.ko

bt8xxx: Unknown symbol hci_suspend_dev (err 0)

bt8xxx: Unknown symbol hci_free_dev (err 0)

bt8xxx: Unknown symbol hci_resume_dev (err 0)

bt8xxx: Unknown symbol hci_alloc_dev (err 0)

bt8xxx: Unknown symbol hci_unregister_dev (err 0)

bt8xxx: Unknown symbol hci_recv_frame (err 0)

bt8xxx: Unknown symbol hci_register_dev (err 0)

insmod: can't insert 'bt8xxx.ko': unknown symbol in module, or unknown parameter

How can i fix the unknown symbol error.

For iMX28 EVK L2.6.35 Linux, I used followed kernel config to enable both wifi and bluetooth with sd8787 module:

Kernel config:

$ insmod /bt8xxx.ko
$ hciconfig hci0 reset

$ iwconfig mlan0 essid test_ap

$ ifconfig mlan0 192.168.1.100 up

// Scan bluetooth device
$ hcdtool scan

By the way, you should the build your kernel first, then updated the Makefile for your sd8787 source code, change the kernel folder to the iMX28 Linux kernel, then build the sd8787 wifi and bt source code. mbt was not needed for 2.6.35 kernel.

Hello Qiang_FSL raymondwang

i compiled the linux kernel first with the above mentioned config parameters, then compiled ltib again with the new kernel. After that compiled sd8787 source code, burned the new os to memory card and booted up while inserting the module am getting errors like this

root@freescale /home/user/mods$ insmod cfg80211.ko

cfg80211: disagrees about version of symbol wireless_send_event

Hello,

raymondwang Qiang_FSL

After modifying the config am issuing these commands

make uImage

make modules

Then i generate the ltib stream files ones again using the command

./ltib -p boot_stream.spec -f

mbt8xxx.ko driver has no sense on linux bluetooth stack on kernel (it only export a char device with HCI interface) ,you can loading it successfully;

bt8xxx.ko is a legacy linux bluetooth driver based on linux bluetooth stack. Make sure you enable kernel bluetooth and hci config and then loading it once again.
