Everyone a great god, the younger brother recently contact Linux system, the small white one, a board, recently will be compiled Ubuntu mirror onto/demo board, all OK, the rise of the can, but in the demo board based on another bat (company control demo principle diagram design, reduced part unused device, but the main components are) after burn, ifconfig only see lo information (boards to eliminate the Ethernet interface, so the eth0 find is normal), but why not find wlan0? Look from the log, rfkill on the electricity in the wlan power supply is normal, but couldn't find equipment, think through a serial port ifconfig wlan0 start up, got wlan0: ERROR while getting interface flags (no to device), online about this problem, the answer is very few, is there a great god answers on the BBS?
