Hi All,
I was trying to configure wifi on beaglebone black board. But i am facing below problems.
I am using TP-LINK TL-WN823N adaptor.
Beaglebone black wifi setup steps :
1) Downloaded the stable kernel 4.4.2 from git.
2) Compiled the kernel and loaded new kernel to beaglebone black.
3) Downloaded the rlt8192eu ( TL-WN823N ) driver code from git.
4) Compiled the driver code for beaglebone black and inserted the module to new kernel.
5) Inserted TL-WN823N adapter to beaglebone black.
Problems :
1) I am getting below messages, i don't know what exactly that message indicates.
