[bluetooth-dev] Kernel Compilation for Axis Devboard_LX
Hi, I'm trying to compile the Bluetooth stack as part of the kernel for
the Axis Devboard LX. These are the steps I followed as stated in a
* Put the include/linux/bluetooth and
drivers/char/bluetooth directories into the same
locations in your kernel tree.
* Add 'source drivers/char/bluetooth/Config.in' to
the end of drivers/char/Config.in (after the endmenu).
* Add the following to drivers/char/Makefile at some
subdir-$(CONFIG_BLUETOOTH) += bluetooth
obj-$(CONFIG_BLUETOOTH) += bluetooth/bt.o
* Add the following to the end of tty_init() in
(you may need to use bt_init_module() instead of bt_init()).
* Reconfigure the kernel (e.g., make menuconfig), and
configure Bluetooth from the new menu alternative.
* Rebuild the kernel.
I seem to be able to run make kernel, make install, and make images
successfully, but when I download it to the board with ktest, it seems
to crash. I did a sermon on the serial port to check the activity as it
is being downloaded. This is what I get the following. Can someone
help me figure out why this happens? Thanks.
