Hi , I am trying to port android 1.5 on IMX27 based platform. But i am blocked in making linux 2.6.27 up.
Its blocking at Freeing init memory . While exploring through the code init/main.c -> rest_init -> kernel_init -> init_post Here it is trying to open the initial consloe sys_open(initial consloe...) is get hanging . ... i could not see any prints after Freeing init memory....... While exploring sys_open -> do_sys_open-> fd_install() --> here after no print statements are coming ..... we have tried ---> console baud rate -- its ok 115200n8 please see the logs below and help me to go forward..... This will help others also. .. . .
