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:
