Hi,everyone. These days, I have been working on android porting. But cannot launch the file of /init in the ramdisk.img.
I have found that the ramdisk.img has been unpacked and mounted to rootfs. In the kernel , I can list the entry of the initial ramdisk by printk function. But when run the first process /init on the rootfs ,Nothing has happened. And I printk the return value of do_execve, the value is correct. The process is executed as follows. start_kernel->rest_init->kernel_init->init_post->run_init_process- >kernel_execve In the kernel_execve ,printk the return value of do_execve. And the value is zero. I think that is right. But why the screen has nothing to export? int kernel_execve(const char *filename, char *const argv[], char *const envp[]) { struct pt_regs regs; int ret; memset(®s, 0, sizeof(struct pt_regs)); ret = do_execve((char *)filename, (char __user * __user *)argv, (char __user * __user *)envp, ®s); if (ret < 0) goto out; / * * Save argc to the register structure for userspace. */ regs.ARM_r0 = ret; printk("ret:%d\n",ret); ... All suggestions will be appreciated. -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
