hi, To build cross toolchain for MIPS, should I choose shared library option. My kernel hangs after : Warning: unable to open an initial console. /sbin/init The function is in init/main.c. static int noinline init_post(void) { .. .. .. if (sys_open((const char __user *) "/dev/console", O_RDWR, 0) < 0) printk(KERN_WARNING "Warning: unable to open an initial console. \n"); (void) sys_dup(0); (void) sys_dup(0); if (ramdisk_execute_command) { run_init_process(ramdisk_execute_command); printk(KERN_WARNING "Failed to execute %s\n", ramdisk_execute_command); } .. .. printk(KERN_WARNING "-- ag. sbin init\n"); run_init_process("/sbin/init"); printk(KERN_WARNING "-- ag. etc init\n"); run_init_process("/etc/init"); printk(KERN_WARNING "-- ag. bin init\n"); run_init_process("/bin/init"); printk(KERN_WARNING "-- ag. bin sh\n"); run_init_process("/bin/sh"); panic("No init found. Try passing init= option to kernel."); }
