In my application I have the Jetson TX1 broadcasting a wireless network for
clients to connect to. On previous releases of L4T, this was accomplised by
doing the following:
-
Adding the file
/etc/modprobe.d/bcmdhd-opmode.conf
with contentoptions bcmdhd op_mode=2
-
Using the create_ap utility to manage
creation of the network (configuration posted below).
After upgrading my Jetson TX1 to the most recent firmware, after enabling the
create_ap service, I get the following errors in my kernel messages:
