Hi,

I just updated the ccimx6sbc to the latest Yocto 2.2-r2, the wireless and bluetooth devices are not working after that. Looking into the kernel booting, I have seen something related to the properties of the mac address:

Unable to update property /wireless:mac-address, err=FDT\_ERR\_NOTFOUND  
Unable to update property /bluetooth:mac-address, err=FDT\_ERR\_NOTFOUND

I have tried to come back to 2.0-r5 which was the Yocto previously installed and did not recognize the devices either.

I there somebody having the same problem to help me out?

Thanks  
Rafael

looks like your board id is not set properly.U-Boot runs the bootscript in order to select the proper DTB. The bootscript uses the U-Boot environment variable $board\_id

As a workaround, you can use the following:  
setenv -f board\_id 129  
boot  
If you want to make the workaround permanent, append that to the bootcmd:  
setenv bootcmd “setenv -f board\_id 129; ${bootcmd}”  
saveenv

Hi,  
Thanks for your answer.  
Actually, I have solved the problem by reset the U-Boot environment to default values:

=\> env default -a

I have performed the firmware installation process from TFTP by following the steps at Digi documentation:

=\> setenv mmcdev 0  
=\> run partition\_mmc\_linux

Then I got the error after the installation is done, the module is now running but I going to test your solution as well.
