[beagleboard] Linux-firmware for Realtek rtl8192cu wifi dongle
Dear I'm using buildroot to build a custom root file system for Beaglebone. My application uses a wifi dongle (Realtek 8192 chipset). I rebuilt kernel image (ver 3.2.0) and the image and wifi dongle work well with Debian root file system. My problem is : the built buildroot root file system get firmware error when modprobe rtl8192cu: # modprobe rtl8192cu [ 194.077442] cfg80211: Calling CRDA to update world regulatory domain Feb 15 08:01:23 beaglebone kern.info kernel: [ 194.077442] cfg80211: Calling CRDA to update world regulatory domain [ 194.171603] rtl8192cu: MAC address: 00:0f:13:59:0f:e1 [ 194.176981] rtl8192cu: Board Type 0 Feb 15 08:01:23 beaglebone kern.info kernel: [ 194.171603] rtl8192cu: MAC address: 00:0f:13:59:0f:e1 Feb 15 08:01:23 beaglebone kern.info kernel: [ 194.176981] rtl8192cu: Board Type 0 [ 255.203972] usbcore: registered new interface driver rtl8192cu # Feb 15 08:02:24 beaglebone kern.debug kernel: [ 255.203643] rtl8192cu:rtl92cu_init_sw_vars():0-0 Failed to request firmware!
