how to use wireless in ubuntu on omap5432-evm

Hi, 

what version of the glsdk are you using?

Is your interface up? if yes fund information about WiLink and wpa_suplicant how to  install them on your system.

Regards,

Boyko

my glsdk version is ti-glsdk_omap5-uevm_6_00_00_07. And I also check the website of wilink. I found all the software of wireless is for the host of AM335X, I am not quite what kind of software is suitable or where can I find a suitable software

Can you use the latest version of the GLSDK, the wilink specifics are part  of the system and don’t need to be  compiled separately

According to your recommendation, I downloaded the latest version of GLSDK: 6.03.00.01. But when I finished installing, I found it was not ubuntu any more instead of a arago project. so is there some other method to make the wireless work on the previous version of GLSDK or make the latest GLSDK to support ubuntu? Btw, do you know whether the omap5432 evm board has a wireless adapter, because according to the information: Interface doesn't support scanning, I guess no, but I am not sure.

Hi,

unfortunetly support for the ubuntu like glsdk was dropped and the new glsdk is using arago project. 

Yes wireless is available. Did you check if your interface is up before executing the command? ( ifconfig wlan0 up )

Yes, I tried this command, but the result is: wlan0: Error while getting interface flags: No such device

Does it means I should add a wireless into my kernel?

Thank you very much

Yes you have to.  you must check if you have  driver for the wifi chip for this particular release.

hello:

These tried some method, finally, I got three files: wl18xx.ko, wlcore.ko and wlcore_sdio.ko then I put it into sd card and start the board used command: modprobe -l. The list:

kernel/drivers/wireless/wl18xx.ko                                               
kernel/drivers/wireless/wlcore.ko                                               
kernel/drivers/wireless/wlcore_sdio.ko

I think it means I can use these three module, then I went to the path: lib/modules/´uname -r´/kernel/driver/wireless, and used command ls to check whether these three files exist or not. It listed three files then I used command: modprobe wl18xx.ko and enter, it shown: FATAL: Module wl18xx.ko not found. So I fell very strange is there something wrong with this step? or is there some other method to install wl18xx.ko file I can try?

thank you very much

best regards

Hi,

maybe the modprobe module database isn't updated on your target system, hence modprobe fails to locate the modules. Try to load the modules w/ absolute path and insmod, according to their dependency on each other.

Hello

Yes thank you very much, by using your method, I succeeded to install these modules on the board, but the problem is when I use command ifconfig wlan0 up, the result is still wlan0: ERROR while getting interface flags: No such device. Do you know why? Thank you very much

Best regards
