Hi , we are porting linux 2.6.27 on imx27 based platform. we did all the platform dependent changes . With this linux is booting till a point and stopping there .. stopping at (VFS) Mounting file system Freeing init memory While debugging through printk we could go till rest_init() -> kernel _init() -> init_post() ---> Going for opening initial console . .... using sys_open() .... After that no prints ....... Can any body help us to go forward ? Thanks in advance , vels Please see the following logs ..
