I've been struggling to get wifi working on my BBB for the better part of a week now. I sort of succeeded at one point, but I couldn't tell how I did it. Anyway, long story short, I noticed this morning that when I start a fresh debian image with my Edimax usb wifi installed, it defaults to AP mode and is broadcasting a SSID called "Beaglebone-710C". This makes sense with my problems because I could see the wifi dongle and see it was recognized, but I couldn't scan or connect. Does anyone know why it would default to AP mode? I think it might have something to do with me accessing the beaglebone via command line over USB? Thoughts? thanks!
Try the following after logging in your BBB via SSH on the USB connection:

I went through the setup procedures from the Doc and was able to get the device up and running but when I try to connect to the device the next day no devices show up.
Below are the steps I try:
I connected the usb type c power port and the OTG data port.
I ran mdt devices and fastboot devices, both commands show no device
Then I try to went through the whole procedure again and I got the same result as discuss in this post.
Any help would be appreciated. Thank you
For those who have experienced the same problem:
make sure that the TPU is connected to the board. If it is not connected when you power up the board the LED will not light up.
I accidentally disconnect it when I try to put the board in a 3D printed case.
I was able to fix this issue by making sure that the board is connected to the TPU.
Following this setup guide: https://developer.android.com/things/hardware/imx7d.html
I am using USB Type-C cable to connect the board and the computer. The computer is using MacOS.
I am unable to flash a default image into the device and throwing the below error:
Looking for devices... This can take up to 3 minutes.
No device has been detected. Is your device correctly plugged in?
If it is already connected, try disconnecting it, then reconnecting it again.
Error: could not prepare device: no device was found: timed out
Stopping adb server...
Stopped adb server..
Can someone help in providing details for the reason it is failing to detect?
I went through the same problem . I disconnected the touch screen , rainbow hat etc and then tried it worked for me. Also it is sometimes like the cable is not connected properly which may cause the issue . Once the cable is connected you will get a green light on the board . Also in case of windows 7 you may have some missing drivers .
Disconnect all your add on devices including LCD Screen/Touch Screen, camera, rainbow hat everything.
and then redo the process
It will Work !!
FYI I just had this problem, it was the USB hub! :)
My laptop has windows 10 but suddenly I encountered Wifi range issue that means my wifi is detecting wifi about one meter but not above that.I also reinstalled windows 10 but still problem exist.
what should I do?
Well the first thing to try would be to open up your laptop. From there you can take a look at the wifi card. It is possible that there is something obstructing it or its not fully in or anything.
The second option which is likely the one you will have to take is to purchase a cheap usb wifi adapter. They can be had for around $10 on Amazon usually. You can get them pretty much anywhere you can buy computers and tech products though.
I met a problem to connect an ios device to the hotspot driven by hostapd which runs on my arm board.
IOS device will take a long time to connect, at last, the wifi signal is shown on status bar, and also got the ip address, but the circle, by the ssid side, won't disappear, it always turns round. This will make user think that the wifi doesn't connected yet, but it really connected.
I have tried some devices to connect the hotsopt, such as android cell phones, windows laptop, they all work correctly.
PS. My English is not good, I hope you could understand what I mean.
if the "circle by the ssid side" keeps showing ，i think your device is still trying to get ip address.
could you please provide us with more detail messages? such as your hostapd configure file and your dhcpd configure file.
I am pretty new to Linux so I apologize if I will ask some really simple stuff.
I am working on a custom board with SAM9G25 and Angstrom distribution as operating system.
The board as to act as a USB Device (Mass storage device), when will be connected to a Host computer. Right now I am simply enabling and removing the g_mass_storage module and the things are working fine.
In the final version, I need to manage the g_mass_storage module according to the connection and disconnection of a USB cable. I tought to use VBUS as an interrupt (also polling will be fine).
Here it comes my problem.
Since the VBUS GPIO is handled by the USB driver i cannot read it's status from userspace. I only see an interrupt count in /proc/interrupt.
I am asking if there is a way to get an interrupt (from the Driver) or to be able to read the VBUS GPIO value when the usb cable is connected/disconnected from the system.
I apreciate any kind of help.
I know this is a bit old, but I found the same problem, and found from userspace you can view the connection status from the udc sys class device. For example, on my architecture the status of USB can be viewed from:
/sys/class/udc/ci_hdrc.0/status
PC connection: configured
Power adapter: powered
Disconnected: not attached
I've read the AM335x architecture can be observed from:
/sys/class/udc/musb-hdrc.0.auto/current_speed
Best of luck
