BBBWL ifconfig...something missing?

Mark7 · December 13, 2016, 12:08am

Hello –

New post as @yahoo spam cluttered up previous.

Per RC Nelson suggestion of booting from different image obtainable at Latest Software Images - BeagleBoard, I made three attempts at resolving lack of wifi on a new BBBWL.

Three images used in these tests:

Debian 8.6 2016-11-06 4GB SD LXQT
https://debian.beagleboard.org/images/bone-debian-8.6-lxqt-4gb-armhf-2016-11-06-4gb.img.xz
Debian 8.6 2016-12-09 4GB SD IoT
https://debian.beagleboard.org/images/bone-debian-8.6-iot-armhf-2016-12-09-4gb.img.xz
NOTE: This image drops my shell connxn after a couple minutes.
BBBW-blank-debian-8.6-lxqt-4gb-armhf-2016-12-05-4gb.img.xz, alluded to by RC Nelson in response to post “Setup Wifi on Beaglebone Black Wireless” this sub-forum.

Below terminal output is consistent across all three images listed above: If anyone has an idea what I am doing incorrectly, assistance will be very much appreciated.
Thank you,
Mark

can you test:

https://rcn-ee.net/rootfs/bb.org/testing/2016-12-12/iot/

made a few more changes to usb0 and wlan0, i'm still chasing down a
new wlcore issue i'm seeing on two of my boards.. (oddly on one, only
when using the microSD)

so, can you also share:

dmesg | grep wlcore

[ 48.035440] wlcore: wl18xx HW: 183x or 180x, PG 2.2 (ROM 0x11)

Hi Robert –

From the most recent 11-06-2016 image just returns…nothing

root@beaglebone:~# cat /etc/dogtag
BeagleBoard.org Debian Image 2016-11-06
root@beaglebone:~# dmesg | grep wlcore

root@beaglebone:~#

BTW, search of an earlier dmesg output (12-05img) showed no results on “wl*”, “wl18*” in the text file. See attached.

Will test your 12-12 IOT and respond back here.

RobertCNelson · December 13, 2016, 2:59am

Uhoh!!

[ 2.351843] bone_capemgr bone_capemgr: Baseboard: 'A335BNLT,'

We have a miss-programmed eeprom!!

Mark, is this a pre-production BeagleBone Black Wireless?

(is the pcb green or black?)

First let's double check the wl1835 works, then i'll walk you thru
re-programing the eeprom..

in /boot/uEnv.txt

add:

dtb=am335x-boneblack-wireless.dtb

and reboot..

Regards,

Mark7 · December 13, 2016, 4:15am

Robert!

Much better. I get WL/BT leds fully lit, which I neglected to mention were previously unresponsive. But USR0 led is kind of in tachycardia. OK, heart rate is down now.

Added your line below line for 1835 which was commented out…

##BeagleBone Black: wl1835
#dtb=am335x-boneblack-wl1835mod.dtb

##Added per RCN
dtb=am335x-boneblack-wireless.dtb

On the reboot, am unable to shell in. So, will reflash your 12-12, swap the comment lines in uEnv.txt and reboot for a looksee.

Thank you for catching that line in the output I attached.
Mark

Mark7 · December 13, 2016, 8:40am

Hi Robert –

Follow up response from earlier.

Board in hand is a production model black received two days ago.

Attached file is result of further testing. In summary, per your suggestion in re add line to uEnv.txt, achieve some success. Ifconfig output is now populated with tether, wlan0, and in one instance softAP0. I can see the MAC address of the BBBWL in my router’s browser window. Connman is functional, without significant errors. Shell connxn is dropped after couple minutes, fairly consistently. Hexdump of eeprom at 0-0050 also included.

Thank you for your assistance,
Mark

Mark7 · December 13, 2016, 12:40pm

Hi Robert –

So yes, success. Although I will still beg your advice on the eeprom problem. I have found that booting from SD card causes some problem with dropping my shell connxn, something not encountered if I just flash the onboard eMMC. I wonder if this is going to be a problem down the road when I want to boot off an 8 or 16 GB card.

Hello,

I am having a problem with getting the USB Ethernet bridge working with the suggestion 12-05-2016 image. When I connect the BBBWL I get the windows partion to show up, which usually means the virutal ethernet port is loaded. Which it does load, but it doesn’t get a 192.168.7.1 address, instead it gets a 169.254.244.251 address. Usually a disconnect and reconnect will fix this problem, but no such luck. I am downloading some of the latest images to try, but I am curious if this is a known issue?

Please note, the driver seems to be working as a my Rev C board is connecting up correctly.

Cheers,

Gregg

Mark7 · December 14, 2016, 8:02pm

Hello Gregg –

Sorry to hear you are having problems with your new board.

What do you get when you type 192.168.7.2 into your web browser? These boards prefer Chrome.

Are you booting from the SD card, or flashing the eMMC and booting from there?

Mark

Gregg_Harrington · December 14, 2016, 8:15pm

Mark,

Thank you. However, I just found at solution. I was trying to SSH into the 192.168.7.2 address which wouldn’t work because the virutal adapter didn’t have an address on the same subnet. However, after reading some other threads I switched to the 12-12-2016 image and everything seems to be working perfectly now. the 12-05-2016 didn’t work after several tries.

I believe it’s probably just an issue with the configuration of that image. The factory image worked as well as the 12-12-2016 image.

To answer your question directly, I was flashing the eMMC and booting from eMMC. The boot seams to work, but I don’t have a serial connector with me to check any settings in the OS.

Thanks,

Gregg

Perhaps I spoke too soon, after rebooting, things seem to be failing again. There appears to be a problem with it providing the IP address to the interface:

Ethernet adapter Ethernet 5:

Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::399c:f19:9a23:f4fb%14
Autoconfiguration IPv4 Address. . : 169.254.244.251
Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . :

Is the USB bridge connection on windows. This is working off of the 12-12-2016 image. The only thing I did with the operating system was log into the connmanctl and connect to a wifi network which required me to turn off the tethering. However, I can SSH into it via the wifi connect that was made. Not sure if this is expected behavior, but I thought I would mention it.

Cheers,

Gregg
