Unable to get WiFi working on BBBW using the latest Debian image

Hey All,

I’m a newb on Linux and having issues getting WiFi to work using the latest Debain image Debian 9.1 2017-08-31 4GB SD LXQT (Stretch). When I try to see the the network interfaces using ifconfig I get only the following 4 and no wlan-

eth0: flags=-28669<UP,BROADCAST,MULTICAST,DYNAMIC> mtu 1500

lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536

usb0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

usb1: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500

I don’t know if this will help but the eprom from my version.sh file is -

eprom:[A335BNLTBBWG0491

Any thoughts on how to fix this or should I start all over again with a new image flash? Any tips/resources on Bluetooth communication on BBBW will also be appreciated.

another case of mis-programed:

GND TP1 then run as root:

dd if=/opt/scripts/device/bone/bbbw-eeprom.dump
of=/sys/devices/platform/ocp/44e0b000.i2c/i2c-0/0-0050/eeprom

reboot and everything will be okay..

Hi Robert,

I have a BBB wireless that also seems to have the same problem as Hamze.
How do I confirm whether or not I also have a faulty eprom version?
Here are some details relating to my installation …

sudo /opt/scripts/tools/version.sh

Hi All,
Same problem here. Which is TP1. I could not find it on the header information .

Look at the pcb, it's on the silkscreen..

Still no luck .

debian@beaglebone:~$ sudo /opt/scripts/tools/version.sh

What do you mean? "you" ^^^ have a BeagleBone Black, NOT the
BeagleBone Black Wireless

The "BeagleBone Black Wireless" is a new model:

Chiming in, this combined with updating to the latest provided release of debian stretch fixed the wireless issues.

GND TP1 then run as root:

dd if=/opt/scripts/device/bone/bbbw-eeprom.dump
of=/sys/devices/platform/ocp/44e0b000.i2c/i2c-0/0-0050/eeprom

Hello, this is what I have done, no result for now:

1. Flashed BBBW with last image Debian 9.2 2017-10-10 4GB SD IoT

2. Grounded TP1

3.

dd if=/opt/scripts/device/bone/bbbw-eeprom.dump

4.
of=/sys/devices/platform/ocp/44e0b000.i2c/i2c-0/0-0050/eeprom

6. Reboot

After reboot:

root@beaglebone:~# cat /proc/device-tree/model TI AM335x BeagleBone Black

`
root@beaglebone:~# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

usb0 no wireless extensions.

usb1 no wireless extensions.

can0 no wireless extensions.
`

It seems that no wireless interface is detected. Am I missing something?

11

are you using beagle bone black or beagle bone black wireless .wireless works only on beaglebone wireless

12

I am using a BB wireless from element14.

^^^ so you just forced it to be a BeagleBone Black here...

YOU need to use:

https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#U-Boot_Overlays

This will give you what you want:

enable_uboot_overlays=1
disable_uboot_overlay_video=1

Regards,

Added
enable_uboot_overlays=1
disable_uboot_overlay_video=1

to /boot/uEnv.txt

Now it does not boot, leds for BT, WL and USR0 stay on.

`

beaglebone login: [ 64.841141] Error: Driver ‘ecap’ is already registered, aborting…

This is last messages on debug pins.

15

“login” yes ‘clearly’ it did not boot… end sarcasm…

What’s your real issue, as it did boot.

Regards,

16

Ok, my mistake, I ‘appreciate’ your sarcasm, but still cannot see any wifi interface.
How can I find the real issue since I cannot ssh connect to BB?
I only have debug messages and a stuck BB.

Okay, now with your /boot/uEnv.txt changes, let's see version.sh again:

sudo /opt/scripts/tools/version.sh

BB is completely freeze with those leds on.
Tried to re-flash, same issue.
I am not able to run any script.

19

How are you powering it?

Use a 5volt DC barrel connector.

Grab this image:

use etcher.io

it'll flash the eMMC..

Regards,

I always use a 5V power supply.
Got the image, flashed SD with Etcher, flashed the BBBW.
Same result as before: it runs until “beaglebone login:”, then freezes.

It can be a problem with my board? I have only one to test.

Thank you for your support.
