Okay. Does this mean I need not modify get_board_mach_type() and get_system_type()? >> I used to get my code tested from Domink but I could not reach him for >> quite some time.

Seems Jiaxun is interested in the board and is willing to help. I have been told that Ingenic is focusing on IoT market and X1000 is intended for IoT segment. I think that they would be selling several 100Ks of chip over the coming years. But I feel Ingenic spends time only on maintaining their Linux port which is usually based on very old kernel version. > Cheers > James Thanks and regards, PrasannaKumar
