[SOLVED] Realtek rtl8712u wifi support
« on: October 31, 2013, 02:12:14 AM »
I am trying to get an ASUS N10 USB WiFi adapter to work.  It shows up as a new USB device with VendorID 0B05 and ProductID 1786.  In dmesg, it fails when requesting "rtlwifi/rtl8712u.bin".  I find that this firmware exists in the x86 repo as "http://repo.tinycorelinux.net/5.x/x86/tcz/firmware-rtlwifi.tcz".  I believed the firmware to be portable across hardware platforms (designed for the USB WiFi adapter).  I attempted to load firmware-rtlwifi.tcz local, extract to a temp mount point, and copy the relevant .bin files to /usr/local/lib/firmware/rtlwifi.  I updated .filetool.lst to make sure the firmware was preserved over reboots.  Unfortunately, it appears that there are some complaints about "staging area", perhaps a corrupt unsquash and perhaps more than the rtl8712u.bin file is required. 

Is it possible to take the x86 firmware-rtlwifi.tcz package and repackage for the Pi platform? 

Relevant output from dmesg:

The "staging directory" warning refers to the kernel tree, not to any local issue ;)
