Linux/BEAGLEBN: Cannot connect WiFi

Prodigy 200 points

Part Number: BEAGLEBN

Tool/software: Linux

Hi community!

I was following instruction on docs Quick Start Guide (HAP AV7L). I have problem on step "Enable Wifi" I tried to connect to Wifi (Setup on wpa_supplicant.conf) but it's always complain "Could not read interface wlan0 flags: No such device"

P/S: I'm using BeagleBone Black Board

    Hello Son,

    Which Processor SDK version you use? Has the ./load_wlcore.sh script successfully loaded the "wl18xx" and "wlcore_sdio" modules. Do you have physical WiLink8 device attached on your BBB?

    Best regards,
    Kemal

    Hi Kemal!
    I'm using "PROCESSOR-SDK-LINUX-AM335X 03_02_00_05" (64 bit binary)
    I have TP-link USB Wifi adapter, but my beagle bone board does not recognize it.
    By the way: How can I do that "Has the ./load_wlcore.sh script successfully loaded the "wl18xx" and "wlcore_sdio" modules" in the instruction do not have this step

    Best Regard,

    Can you post the output of lsusb command executed from the BBB console while the TP-link USB Wifi adapter is attached?

    Hi Kemal!
    Here is the result (I'm using TP-Link Wifi USB WN725N)

    Please, see this post. For BBB replace the tisdk_am57xx-evm_defconfig with tisdk_am335x-evm_defconfig and am57xx-evm-reva3.dtb with am335x-boneblack.dtb

    Hi Kemal!
    I was following your attached link and I'm having problem at step (8), I cannot find the file "am57xx-evm-reva3.dtb", I think my SDK support for processor am335x so I tried to find file "am335x-evm-reva3.dtb" but it's not available too.

    Find the am335x-boneblack.dtb for BBB (BeagleBone Black).

    I found it.
    By the way, on the "sudo scp" commands, I see the paths "/media/<username>/boot/" or "/media/<username>/rootfs/boot/", when I use software WinSCP try to enter the SD Card folder, but I just see media/ram and not another folders available
    P/S: I copied "am335x-evm-linux-03.02.00.05.img" into SD Card, does it influence to this step?

    Just attach the SD card to your host and transfer the new files into your SD card. You can use whatever software you want to do this cp, scp, rsync, dd or use the GUI tools Ctrl+C, Ctrl+V

    How about the paths "/media/<username>/boot/" & "/media/<username>/rootfs/boot/", I must be copy to these paths or can I create custom folders on SD card and copy to its

    OS on SD Card: am335x-evm-linux-03.02.00.05.img (Arago)
    I downloaded from this link: software-dl.ti.com/.../am335x-evm-linux-03.02.00.05.img.zip

    Right. First complete this step  and create a SD card. You will have 2 partitions on your SD card, then copy the new generated kernel with TP-link USB Wifi adapter support and its modules in proper places into these two partition.

    Hi Kemal!
    I followed the instruction to creat a SD card, then I created these custom folders on SD Card "/media/<username>=root/boot", "/media/<username>=root/rootfs/boot" and "/media/<username>=root/rootfs/lib/modules"

    On step "Copy the needed dtb, kernel and module in a proper places at your SD card.", I used Linux host system to scp folders into SD card through commands

    - sudo scp -r board-support/linux-4.4.32+gitAUTOINC+adde2ca9f8-gadde2ca9f8/arch/arm/boot/zImage root@192.168.7.2:/media/root/boot
    - sudo scp -r board-support/linux-4.4.32+gitAUTOINC+adde2ca9f8-gadde2ca9f8/arch/arm/boot/zImage root@192.168.7.2:/media/root/rootfs/boot
    - sudo scp -r board-support/linux-4.4.32+gitAUTOINC+adde2ca9f8-gadde2ca9f8/arch/arm/boot/dts/am335x-boneblack.dtb root@192.168.7.2:/media/root/boot/
    - sudo scp -r board-support/linux-4.4.32+gitAUTOINC+adde2ca9f8-gadde2ca9f8/arch/arm/boot/dts/am335x-boneblack.dtb root@192.168.7.2:/media/root/rootfs/boot/
    - sudo scp -r targetNFS/lib/modules/4.4.32-gadde2ca9f8 root@192.168.7.2:/media/root/rootfs/lib/modules

    But the last command, scp folder "4.4.32-gadde2ca9f8" into SD Card takes a long time. Should I copy entire folder "4.4.32-gadde2ca9f8" into SD card or can I copy some neccessary folders on folder "4.4.32-gadde2ca9f8"? (And which are neccessary folder for Wifi adapter? )

    Regard,

    These two paths "/media/<username>/boot/" and "/media/<username>/rootfs/" are on your host machine. They are the two partitions of your SD card. Attach the SD card to your host machine these two partitions will be created and mounted automatically, then copy the needed files. Refer to the targetNFS directory hierarchy, the structure on your SD card and lib/modules/4.4.32-gadde2ca9f8 should be the same.

    Hi Kemal!

    On my host machine just display "boot" folder, I do not see folder "rootfs".

    I tried to create custom folder "rootfs" on host machine and use the commands "sudo scp -r..." to copy, but when I do the command "root@am57xx-evm:~# modprobe rtl8192cu" on beagle bone, it's not work and display "modprobe: FATAL: Module rtl8192cu not found in directory /lib/modules/4.4.32-gadde2ca9f8"

    Why your board name is "root@am57xx-evm" it should be "root@am335x-evm" for BBB?

    You do not have the rtl8192cu.ko within /lib/modules/4.4.32-gadde2ca9f8/ directory. Please, revise the steps you have done so far. Probably you have skipped something.

    I'll check the step
    How about the folder "rootfs" on host machine?, I cannot find it

    The "rootfs" on host machine is the second partition of the SD card.

    Hi Kemal!

    I found the "rootfs" folder. Tommorow I always attached SD card on Beagle Bone board then connect the BB board to the host system, now I attached SD card on card reader then connect directedly to the host system, finally folders "boot" and "rootfs" are displayed. And I copied neccesary folder into the SD card.

    But when I run the file "/usr/share/wl18xx/sta_start.sh" on BB board it's still not work.

    Here is the result when I run file "/usr/share/wl18xx/sta_start.sh"

    "Successfully initialized wpa_supplicant
    Could not read interface wlan0 flags: No such device
    nl80211: Driver does not support authentication/association or connect commands
    nl80211: deinit ifname=wlan0 disabled_11b_rates=0
    Could not read interface wlan0 flags: No such device
    wlan0: Failed to initialize driver interface"

    Here is the resule when I excuted command "modprobe rtl8192cu"
