BBGW wlan0 setup: wlan0/softAp0 missing and can't connect

Hi guys,
I’m facing a problem with wlan0. Basically I can’t make it work anymore. I used to connect to my wlan in the past week (https://beagleboard.org/discuss?place=topic%2Fbeagleboard%2Fz7_EdRpFL1M%2Fdiscussion) but I made changes/reflash and I can’t figure why It’s not working now.

It’s easier to list what I’ve done.

Current config:

Image: Debian 8.6 2016-11-06 4GB SD SeeedStudio IoT (bone-debian-8.6-seeed-iot-armhf-2016-11-06-4gb.img)

Kernel: Linux beaglebone 4.4.30-ti-r64 #1 SMP Fri Nov 4 21:23:33 UTC 2016 armv7l GNU/Linux

  • Flash it in a sd card

sudo dd if=/media/gorgo/Windows/bone-debian-8.6-iot-armhf-2016-12-09-4gb.img of=/dev/mmcblk0 bs=4M sudo sync

  • Insert into the board and it boots.

  • ifconfig

Boot: U-Boot SPL 2016.11-rc3-00002-g73df7f7 (Nov 04 2016 - 15:20:36)Trying to boot f - Pastebin.com

I edited /boot/uEnv.txt uncommenting and reboot

dtb=am335x-bonegreen-overlay.dtb

For the BBGW, you don't need to do ^ that, as that "setup" is pretty
much the default.. You just want to disable eMMC, use the new U-Boot
Overlays..

http://elinux.org/Beagleboard:BeagleBone_Debian_Image_Migration#U-Boot_Overlays

enable_uboot_overlays=1

disable_uboot_overlay_emmc=1

Use this latest image:

Hi RobertCNelson,

are you sure about the uEnv.txt?
I put # in front of dtb=am335x-bonegreen-overlay.dtb and uncommented the two lines you told.
I rebooted and:

  • I lost my univ-all slot:

debian@beaglebone:~$ cat /sys/devices/platform/bone_capemgr/slots 0: PF---- -1 1: PF---- -1 2: PF---- -1 3: PF---- -1

  • I’m not able to read P8 gpio anymore.

I had this problem last week (https://forums.adafruit.com/viewtopic.php?f=49&t=111784&p=559590#p559590) and we fixed that uncommented the line I told you.

For the image:
In the second part of the topic I showed you a nightly build test with bone-debian-8.7-iot-armhf-2017-02-19-4gb.img. Is it not the one you told me? Should I try BBB-blank, BBBL-blank or debian-8.7 instead?

Thank you

You can manually add that overlay to /boot/uEnv.txt

Did you mean with adding:
enable_uboot_cape_universal=1 ?

It doesn’t work.
And I have set too:
cmdline=coherent_pool=1M net.ifnames=0 quiet cape_universal=enable

This is my current uEnv.txt: http://pastebin.com/0Jv0qGxM

This is the boot from the debug serial: http://pastebin.com/Bdhq0XvG

The wifi problem is still present though :frowning:
