I am having problems with wifi dongles with the pocketbeagle.

I have two dongles:

1) Edimax EW-7811Un:

EDIMAX - Wireless Adapters - N150 - N150 Wi-Fi Nano USB Adapter, Ideal for Raspberry Pi

2) tp-link TL-WN725N V3

TL-WN725N | 150Mbps Wireless N Nano USB Adapter | TP-Link

I have tried them in two configurations:

1) I cut a usb-a female cable and wired it to the PB in accordance with:

https://i1.wp.com/www.teachmemicro.com/wp-content/uploads/2018/03/pocketbeagle-usb-type-a.jpg?w=590&ssl=1

2) 2-port usb hub from tindie

2/4-port USB 2.0 HUB Cape for PocketBeagle from microwavemont on Tindie

Voltage Readings

Pin Function USB Power 5V 0.8A HUB 5V 8A power supply

P1-5 Vbus 0 0 0

P1-7 VIN 4.97 5.152 5.163

P1-14 3.3V 3.422 3.422 3.422

P 1.24 Vout 4.925 5.108 5.118

Set up:

1) Image: https://debian.beagleboard.org/images/bone-debian-10.3-iot-armhf-2020-04-06-4gb.img.xz

2) apt update

3) apt upgrade

4) init 6

5) cd /opt/scripts/tools / git pull || true

6) /opt/scripts/tools/update_kernel.sh

7) init 6

8) /opt/scripts/tools/version.sh

9) init 6

10) apt update

11) apt upgrade

12) init 6

ThingsI've tried:

1) Edimax driver update:

How to resolve EW-7811Un built-in driver issues in Linux kernel v3.10 or higher : EDiMAX (freshdesk.com)

2) tp-link driver update

Download for TL-WN725N | TP-Link

3) Installing Wifi dongle (rtl8192cu) on BeagleBone Black (google.com)

4) Overview | Setting up WiFi with BeagleBone Black | Adafruit Learning System

5) PocketBeagle Quick Start Guide and Connecting t... | element14 | BeagleBoard

6) Error using connmanctl> enable wifi BBBW (google.com)

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

7) Derek Molloy's book ch12 pg 565

apt-cache search RTL8188

- nothing found

Things I have not tried:

1) Compiling my own kernel per Derek Molloy:

How are you powering the Beagle and hub? Note that USB 2.0 standard is
that only 0.5A is available (and often needs a powered hub to get that). If
the beagle is being powered from a USB connection, you will have much less
current available for any devices connected to it, as the Beagle itself
requires some fraction of the available power (it's why Beagle Bone Black
is recommended to use a barrel connector rather than USB when flashing the
eMMC). A 5V 8A supply is not doing much unless you've wired directly to the
hub 5V source (or P1-1

Since the WiFi adapter runs a micro-radio, you likely need a higher
current just for it, so powering from the USB into the Beagle may not be
viable. I know R-Pi boards with WiFi operate off a USB connection, but that
is not a data connection -- just a specialized power mode which modern hubs
can recognize and provide a touch more current.

Pardon, but why the "init 6" (especially as Debian has adopted the
systemd start up, deprecating "init" mode).

Okay -- you've probably read the referenced PDF then, as the downloads
are source needing to be compiled. But I note
"4. This is a beta version; unknown bugs may still exist. The formal
version is coming soon."
and that was three years ago... Only the Mac version has seen updates newer
than the Linux beta. The beta is also only "tested" up to kernel 4.4.3, and
recent Beagle images are on what, 4.19.x

1. Update: sudo apt-get update && apt-get upgrade && && apt-get
dist-upgrade and reboot if you updated the kernel
2. Connect the device. lsusb should show 2357:0107
3. Install required packages: sudo apt-get install gcc-6 git

git clone https://github.com/jeremyb31/rtl8192eu-linux-driver.git
cd rtl8192eu-linux-driver
sudo make
sudo make install
5. Reboot and check that the kernel module is loaded by running: lsmod
6. Use your network-interface to connect to the WLAN. You could use the
pre-installed NetworkManager for that.
(7.) Edit NetworkManager.conf as root: sudo kate

Those might be of concern. Some error in the bus voltage level? You
reported 0V? But if you were jumpered to the 5V supply (next pin over), you
should not be seeing 0V at all. Recheck your cable -- do you have
continuity between those pins (with the cable off the Beagle)?

I'm not sure what the problem is other than the board isn't recognizing the device.

I do know I am tired of copying and pasting

/sbin/route add default gw 192.168.7.1

echo "nameserver 8.8.8.8" >> /etc/resolv.conf

ping www.google.com

and would like to simply connect to the device living on my network like I do for my BBB-by hardline ethernet, BBB-wifi through wifi, and BBB-AI by hardline ethernet. I did have issues with the BBB-AI connection being troublesome by wifi.

I've worked through about a dozen and half different web pages describing how to fix the wifi dongle without success.

The wifi router is less than 5 feet away so at this stage of the game, wifi range doesn't matter.

I've been using init 6 and init 0 for reboot and shutdown since first reading Derek Molloy's book. Does this cause a problem? I can start using shutdown -h now and reboot.

I did come across the debian wifi wiki, but missed the "Guide". Thank you for pointing it out. PB no usb.jpg

Those might be of concern. Some error in the bus voltage level? You
reported 0V? But if you were jumpered to the 5V supply (next pin over), you
should not be seeing 0V at all. Recheck your cable -- do you have
continuity between those pins (with the cable off the Beagle)?

Measurements were with nothing connected. There is continuity when connected.

I started the "Guide" on the pb mounted on 2/4-port USB 2.0 HUB Cape for PocketBeagle from microwavemont on Tindie.

Did not get lsusb to show 2357:0107. After step 2. Abandoned process on that one in case the two usb hub cape was problematic, and restarted on a PB with only headers connected.

1. Update: sudo apt-get update &&

apt-get upgrade

The following packages have been kept back:

c9-core-installer

0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

apt-get dist-upgrade

The following packages have been kept back:

c9-core-installer

0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

and reboot if you updated the kernel

2. Connect the device. lsusb should show 2357:0107
3. Install required packages: sudo apt-get install gcc-6 git build-essential
4. Get the latest driver from ?GitHub and install it:
git clone https://github.com/jeremyb31/rtl8192eu-linux-driver.git
cd rtl8192eu-linux-driver
sudo make
sudo make install
5. Reboot and check that the kernel module is loaded by running: lsmod
6. Use your network-interface to connect to the WLAN. You could use the
pre-installed NetworkManager for that.
(7.) Edit NetworkManager.conf as root: sudo kate
/etc/NetworkManager/NetworkManager.conf
Append the following:
[device]
wifi.scan-rand-mac-address=no
Save and run: /etc/init.d/network-manager restart

I can not possibly be the unique case of these problems. I'm certainly not that special and it's rather frustrating.

This morning, I setup a brand spanking new pocketbeagle straight out of the package and have very concerning errors on installation of the most recent image. Nothing whatsoever is connected other than the USB cable to my PC. And the device is sitting on a grounded anti-static pad.

[ 443.396338] usb usb2-port1: over-current condition

[ 443.440703] musb-hdrc musb-hdrc.1: VBUS_ERROR in a_wait_vrise (81, <SessEnd), retry #1, port1 0000010c

full dmesg below

It is very concerning to have an overcurrent situation right out of the box.

Additional research indicates that these errors may be related to a malfunctioning 25Mhz crystal oscillator used for USB timing. At least that's what I founnd on a TI site discussing their usb controllers related to these errors.

This is beyond my understanding of device construction, but can I be burning up my usb timing crystal immediately on 1st plug in?

Is this a typical subcomponent of a USB hub?

Or is this simply the confirmation of the lack of any RTC on the PB?

I proceeded with the usual set up:

Set up:

1) Image: https://debian.beagleboard.org/images/bone-debian-10.3-iot-armhf-2020-04-06-4gb.img.xz

2) apt update

3) apt upgrade

4) reboot <--- I didn't use init 6 lol

The above errors were not present after upgrade, but the following errors remain:

[ 0.001560] timer_probe: no matching timers found

[ 0.159609] l4_wkup_cm:clk:0010:0: failed to disable

[ 1.708436] musb-hdrc musb-hdrc.1: VBUS_ERROR in a_wait_vrise (80, <SessEnd), retry #3, port1 0008010c

5) cd /opt/scripts/tools / git pull || true

6) /opt/scripts/tools/update_kernel.sh

7) reboot

same dmesg as after upgrade

8) /opt/scripts/tools/version.sh

9) reboot

10) apt update

11) apt upgrade

12) reboot

Do you have standoffs on that board...Sitting on an anti-static pad
could be making contact with some underside circuitry, causing unexpected
voltages on some pins.

I do not have a standoff on a pocket beagle.

But the problem is recurring on all models right side up, upside down with and without 2/4-port USB 2.0 HUB Cape for PocketBeagle from microwavemont on Tindie installed or a female pin block that keeps any pins or pads from contacting the static pad.

lsusb -v & udevadm trigger --> dmesg below

I simply can not believe that the random selection process of purchasing 4 pb's over a course of a year yielded four defective devices in my possession.

OK, I'll admit it: I purchased 6 and burned up 2 pulling too much power from a gpio. That's my simple attempt at humor.

Have you tried connecting a Powered USB HUB to the USB board attached to the PocketBeagle so the WiFi module is not drawing current directly from the PB?

It seems there is an over-current condition being reported:

126.004560] usb usb2-port1: over-current condition

Cheers,

Jon

Yes.

These are the voltage readings with nothing connected on several power supplies options I have:

Voltage Readings

Pin Function USB Power 5V 0.8A HUB 5V 8A power supply

P1-5 Vbus 0 0 0

P1-7 VIN 4.97 5.152 5.163

P1-14 3.3V 3.422 3.422 3.422

P 1.24 Vout 4.925 5.108 5.118

I can not talk to the pb when its on the 5V 8A, but nothing shows up in either on usb power or on a usb power hub.

I just connected it to see if it had any voltage impact.

Thank you.

Pat

My apologies, the 5V 0.8A hub is mislabeled.

It is 5V 3A output. The 0.8A was the input 120VAC rating.

Well I was hopeful the kernel update today would help with the issues, but no such luck.

I powered the board at VIN with a 5VDC 8A power suppy with the 4-usb port version of 2/4-port USB 2.0 HUB Cape for PocketBeagle from microwavemont on Tindie

Have additional over-current errors.

If I am not supplying the information that is helpful for solving the problem, please let me know.

Well I was hopeful the kernel update today would help with the issues, but no such luck.

I powered the board at VIN with a 5VDC 8A power suppy with the 4-usb port version of 2/4-port USB 2.0 HUB Cape for PocketBeagle from microwavemont on Tindie

Have additional over-current errors.

If I am not supplying the information that is helpful for solving the problem, please let me know.

How exactly do you have the usb port wired?

Yes, I tried it exactly per that same image with a variety of power supplies.

I have also been using the hubs from tindie, just in case I'm being simple minded, but I've quadruple confirmed. Measure twice cut once.

I have also connected 5 8A potential supply power directly to P1.01 and have the usb connected.

reconnected again.

Problem fixed!

Power into P1.01 from 5VDC 8A max supply & the usb-pc tether, of course.

Female USB socket tied in per above image.

With nothing connected:

Well I have no idea what the problem was.

I have now disconnected the power to P1.01 and it is working fine with only power through micro-usb port without PC tether.

Perhaps Im just a rambling lunatic.

Again thank you.

The 2/4-port USB 2.0 HUB Cape for PocketBeagle from microwavemont on Tindie works well, but I must not have been getting full continuity by only friction fitting the posts onto the PB.

Once I soldered a header onto the PB and then used that to connect to the hub, it worked well.

I don't have any financial interest in this product, but without PB interconnects/cases/shields readily available on the market, I would recommend them. Please don't reply recommending an altoids can.

Note of caution: connman seems to be particular about which of the usb hubs the dongle is plugged into. Would find services plugged in one side, but did not on the other.

Note also that neither the edimax dongle nor the tplink dongle required additional power beyond the micro usb tether. Nor did either require any driver updates.

Cheers!
