yocto build for tinkerboard enable bluetooth and wifi
#1
Hi Forum,

I was successfully able to build core-image-weston using yocto. I am now struggling to get the wifi and bluetooth working. I was unable to discover any devices using bluetoothctl and the same with connman. Any inputs will be welcome. 

Regards

Hi aparker,

I think your kernel driver does not match to tinkerboard.
Where is your kernel come from ? which version ?

I am using the upstream kernel 4.12. Let me try to use the rockchip kernel 4.4 and see if that changes anything. I thought the bluetooth and wifi modules are part of the rk-firmware which i was able to install into my file system. please see the link ( https://github.com/rockchip-linux/meta-rockchip/blob/master/recipes-bsp/firmware-rk/firmware-rk_git.bb ) . Let me try your suggestion to use the rockchip kernel.

Hi aparker,

I use this kernel (https://github.com/TinkerBoard/debian_kernel) for TinkerBoard.

This is released for TinkerBoard.   Rockchip kernel might not have bt/wifi driver ...  Undecided

Hi,

The defconfig you need is miniarm-rk3288_defconfig
Please take a refer to this wiki, https://tinkerboarding.co.uk/wiki/index.php?title=Software#Kernel.
