Connect RTL8723bu wifi + bluetooth dongle driver to Galileo

Hi,

I am trying to setup wifi capability on Galileo. I am using EDIMAX EW-7611ULB dongle. I am using 3.8.7 Yocto. Upon submitting the make command, I get the following error.

I appreciate your help.

Thanks,

Udaya

Hi,

1. Copied the file rtl8723BU_WiFi_linux_v4.3.16_14189.20150519_BTCOEX20150119-5844.tar.gz on the SD card

2. Booted Galileo with SD card

3. Used command tar xvf to unzip the file.

Couldn't make anything work with the above steps.

Then,

1. cloned file rtl8723BU_WiFi_linux_v4.3.6.11_12942.20141204_BTCOEX20140507-4E40.tar.gz from github

2. unzipped it in folder /home/root/rtl8723bu

3. executed the 'make' command as mentioned before.

Thanks,

Udaya

Hi,

I was finally able to execute the install.sh script that came on the CD of the dongle. However, the install.sh script also errored with the above error statements related to make.

Thanks,

Udaya

Hi Udaya,

 

 

Thanks for the information provided. We have found that this particular error is related to the Kernel headers package necessary to compile an external module. Please take a look at this link: https://github.com/lwfinger/rtl8723bu/issues/30 https://github.com/lwfinger/rtl8723bu/issues/30. We recommend you to post this question in the issues tab, since Lwfinger is the developer he could give you a more accurate answer.

Hi,

Lwfinger gave the following response:

You have not installed the kernel headers. As the exact steps are distro dependent, I cannot tell you what you need to do. Check with your distro.

I am not sure what this means.

Thanks,

Udaya

Hello,

I looked at the error message given above and the feedback from lwfinger and tried to tie them together. The makefile is looking for object modules in the path /lib/modules/3.8.7-yocto-standard/build. However there are none. The kernel source code is in the path /lib/modules/3.8.7-yocto-standard/kernel.

The makefile has the following:

KVER := $(shell uname -r)

KSRC := /lib/modules/$(KVER)/build

MODDESTDIR := /lib/modules/$(KVER)/kernel/drivers/net/wireless/

and

modules:

$(MAKE) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) -C $(KSRC) M=$(shell pwd) modules

How should I change the KSRC statement?

Thank you.

Udaya

Hi Udaya,

 

 

Kernel modifications are out of our support scope, however we would recommend you to check the http://www.yoctoproject.org/docs/1.8/mega-manual/mega-manual.html# bsp-filelayout-kernel Yocto Project Mega-Manual, in the chapter 4 you can find the "Modifying the Kernel" section that could help you in order to reach it. Also, please take a look at the http://alextgalileo.altervista.org/blog/reconfiguring-linux-kernel-adding-drivers-galileos-linux-ima... Reconfiguring Linux kernel and adding drivers into Galileo's Linux image, it could interest you too.
