wireless cape bricks the beaglebone

Yes I have tried doing this without the uEnv.txt edits. The wifi cape lights do not even turn on and

worst part is when I get the turned on, I can not log into the beagleboard

Try changing the dtb line from:

dtb=am335x-boneblack-overlay.dtb

TO

dtb=am335x-boneblack-wl1835mod.dtb

I came across a lot of frustration from this discussion, from 2016, 2017, attached to the wireless cape readme file:

BBONE-GATEWAY-CAPE_README_11292016_v0 1.pdf

  (the discussion shows up below the pdf rendering)

M_Hudson points out the the cape enable line in uEnv.txt says to use "BB-BONE-WL183"

While the technical details for the wireless cape say on this page:

Wireless Connectivity Cape for BeagleBone Black

that it uses "WL1837MOD"

Is there a  dtb=am335x-boneblack-wl1837mod.dtb that would work???  Of course, you'd need that dtb file, and I don't see that the instructions say where the file would come from. I see on my BBB-Wireless (not the cape, but the BBB with wireless on the main board), that I have the file mentioned above by Jon Morss,  am335x-boneblack-wl1835mod.dtb  but no wl183 or wl1837.  This is with the debian 9.5 verson (October 2018) .  Maybe an older version of debian had the correct dtb?

Hi thanks for the reply Allen.

The am335x-boneblack-wl1837mod.dtb file is there in the directory /boot/dtbs/4.14.71-ti-r80

All you have to do is use it, and I have tired it with the uboot_overlay_addr0=/lib/firmware/BB-GATEWAY-1837-00A0.dtbo

and without.

Both fail to allow me to Putty back into the Beagle.

When I use am335x-boneblack-wl1837mod.dtb the wifi unit light up (which seems operational ?) and I can no longer putty to the Beagle.

Its a brick.

Can not see video output either.  It becomes useless. I have reloaded the OS about 4 times so far today onto the SD card because the

wrong combination just stops access to the board altogether.

I need help..
