My target is Alchemy DB1200. I use crosstool-ng to build MIPS cross toolchain and ptxdist to build ext2 filesystem. kernel version:linux-2.6.22 I added some printk's linux/init/main.c to see what happens. ############################################################# . . . (void) dup(0); (void) dup(0); /* * We try each of these until one succeeds. * * The Bourne shell can be used instead of init if we are * trying to recover a really broken machine. */ if (execute_command) run_init_process(execute_command); printk("before /sbin/init\n"); run_init_process("/sbin/init"); printk("before /etc/init\n"); run_init_process("/etc/init"); printk("before /bin/init\n"); run_init_process("/bin/init"); printk("before /bin/sh\n"); run_init_process("/bin/sh"); it hangs after /sbin/init What could be the problem? I tried to give init="/sbin/abhi" "abhi" is an executable file with printf statement. but kernel stops after : Waiting 10sec before mounting root device... scsi 0:0:0:0: Direct-Access Ut163 USB2FlashStorage 0.00 PQ: 0 ANSI: 2 sd 0:0:0:0: [sda] 983808 512-byte hardware sectors (504 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Assuming drive cache: write through sd 0:0:0:0: [sda] 983808 512-byte hardware sectors (504 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Assuming drive cache: write through sda:<7>usb-storage: queuecommand called sda1 sd 0:0:0:0: [sda] Attached SCSI removable disk sd 0:0:0:0: Attached scsi generic sg0 type 0 VFS: Mounted root (ext2 filesystem) readonly. mount_block_root: name=/dev/root fs=ext2 flags=32769 Freeing unused kernel memory: 156k freed Warning: unable to open an initial console. ---ag: /sbin/abhi
