Beaglebone black wireless and wl18xx ...

Hi,
I'm using Beaglebone black wireless with Debian 9.13 and kernel 4.19.135-bone54,
The wl1835 doesn't work on LiPo battery when DC 5v is disconnected,
I read about diode D2 on the board ...
I would like to know if this diode is the solution ?
Thanks.

it is, at least according to the bbbw schematic
at https://github.com/beagleboard/beaglebone-black-wireless/blob/master/BeagleBone_Black_Wireless_SCH.pdf
(top left corner of the 'wifi module' section).

for unknown reasons the bbbw designers have marked it 'dnp' (do not populate)
on the schematic.

regards
az

Hi,
Yes, I saw ...
D2 is not present on the board, I will do the test with D2 ...
The BBBW doesn't shutdown correctly without wifi, some process block ...
I have also a problem with ADC power,
The ADC power (P9.32) doesn't fall to 0v and I use this signal (With BBB) to disconnect my LiPo ...
I try to find another way,
Thanks.

Hi,
With diode D2 the shutdown process works,
And wifi is available on battery ...
