BB-W1-P9.12-00A0.dtbo, uboot overlay did not work correct

[ASbetebe]

Hi,
i have a problem with my DS18b20 temperature Sensor.

Wired:
Black = GND
Red = 3,3V with resistor 4,7k to Data
Yellow = Data = Pin9.12

My System
Beaglebone Black
Static hostname: beaglebone
Icon name: computer
Machine ID: 206cba11664750b7d62ec81d5cd92719
Boot ID: 26e3097bb8794bdc99f4fefb772370aa
Operating System: Debian GNU/Linux 9 (stretch)
Kernel: Linux 4.14.108-ti-r104
Architecture: arm
BeagleBoard.org Debian Image 2018-10-07

I have made the following changes in the uEnv.txt
uboot_overlay_addr4=/lib/firmware/BB-W1-P9.12-00A0.dtbo

disable_uboot_overlay_video=1
disable_uboot_overlay_audio=1
disable_uboot_overlay_wireless=1_

If I list all the devices now.
/sys/bus/w1/devices$ ls
Then always different bus addresses are listed there but none with a correct address.
Example
00-140000000000
00-540000000000
00-940000000000
w1_bus_master1 --> This is always listed identically

What am I doing wrong?
Thanks in advance

@ASbetebe i've had reports that 4.19.x fixes the issue:

cd /opt/scripts/
git pull
sudo /opt/scripts/tools/update_kernel.sh --ti-channel --lts-4_19
sudo reboot

Regards,

[ASbetebe]

Good morning,

thank you Robert.
I did the update but unfortunately I still have the same problem.

Are there any othe solutions ?

I'm having problems too and also using 4.14.71. My BBB stopped connecting to the Internet via USB and I have not been able to get it to connect again no matter what. I've used different cables, different computers, etc. No luck. So no luck getting 4.19 yet.

[WalterCEden]

I was able to get my BBB with a hardwired Ethernet cable (still can't get there via USB) and updated to 4.19 using the information above. I have the same sensor configuration as mentioned in the initial post. I checked in /sys/bus/w1/devices and don't see anything other than the w1_bus_master1 directory. Is there something else I can try?

I ran dmsg and found this at the very end of the listing.

gpio-60 (P9_12): enforced open drain please flag it properly in DT/ACPI DSDT/board file

I do not have a microSD card inserted

uname --all gives this output

Latest update! I see the sensor in the directory tree! Apparently, I had a bad connection that I fixed when I rewired the board today. Woohoo! It's always a hardware problem right? Now I can get on to writing my C code to read the temp!
