Tool/software: Linux
Hi All,
Our system is based on the TI_SDK am335x-evm-01.00.00.03 + wilink driver R8.6_SP1.
(linux kernel 3.14)
We encounter a problem about wifi driver: there is no value in /proc/net/wireless.
We following the below steps to setup our system:
1. build image from TI_SDK am335x-evm-01.00.00.03 and install on the sd-card
2. build wifi driver and install to sd-card (update to R8.6_SP1,following this page:
processors.wiki.ti.com/.../WL18xx_System_Build_Scripts)
We want to know why it's empty in the /proc/net/wireless. Besides,
the iwlist can't use in our system either.
