Ok, maybe I shouldn’t have but I bough t a BBB wireless on ebay. I have it up and running but I see no wlan0 interface but I do see an eth0. Could someone have changed the eprom so this board thinks it is a regular BBB?

version.sh shows this:

eprom:[A335BNLTO
model:[TI_AM335x_BeagleBone_Black]
dogtag:[BeagleBoard.org Debian Image 2019-08-03

Any help would be appreciated.

GND TP1 and run this "one" line command:

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

^that's "one" line...

then run:

sudo /opt/scripts/tools/version.sh | grep eeprom

Thank you Robert, I hope you receive this, as I must admit I’m having issues with the forums and can’t seem to find where my post is located there.

After much searching, I was able to get the board functional using an overlay but would very much prefer to set it so that the it detects the correct configuration by default.

I used this in the uEnv.txt file.
enable_uboot_overlays=1
dtb_overlay=/lib/firmware/BB-BBBW-WL1835-00A0.dtbo

Do you know how I can get it to detect the board as above without having to use the overlay?

Thank you again.

This should fix it back to the correct stock setting:

I may have mistakenly assumed those commands you provided were to view what was in eeprom and not change it. I will run those commands as soon as I can. Sorry for the misunderstanding.

Here is the output, is this what was expected?

fpp@FPP:~$ sudo dd if=/opt/scripts/device/bone/bbbw-eeprom.dump of=/sys/devices/platform/ocp/44e0b000.i2c/i2c-0/0-0050/eeprom

Double check your gnd wire, eeprom has a write protect.. i forget
where TP1 is located, but it should be labeled and you tie a gnd wire
from the header to it..

You can reboot, but if it fails to boot, you can use this special
blank image that'll boot any blank eeprom board:

Is this better?

fpp@FPP:~$ sudo dd if=/opt/scripts/device/bone/bbbw-eeprom.dump of=/sys/devices/platform/ocp/44e0b000.i2c/i2c-0/0-0050/eeprom
