Hello,
I need to use RTL8188CE Wireless NIC in my BPI-R2. I build the following modules in EMMC image.
- kmod-cfg80211… cfg80211 - wireless configuration API
- kmod-mac80211… Linux 802.11 Wireless Networking Stack
- kmod-rtl8192ce… Realtek RTL8192CE/RTL8188CE support
But this error occurred in the system startup log
[ 23.592788] cfg80211: exports duplicate symbol __cfg80211_alloc_reply_skb (owned by kernel)
And I use insmod to load rtl8192ce module. The kernel log output lots of “Unknown symbol” messages.

I try to change some source code, but it doesn’t work.
