Posted March 10, 2020 09:12:25In Part 1, we covered the basics of how to fix the mount/nameline error in Android.
In Part 2, we’ll dive deeper into some of the common problems that mount/nomeline can cause.
This article should help you diagnose mount/nonmount issues in Android (and other Android devices) and make them a lot easier to fix.
We’re going to use the Android NDK as an example.
If you’re using a different NDK, you’ll see that our example code doesn’t work at all.
If you want to learn how to write a properly working Android NDk, you can download the source code from Github.
It includes a few example applications that you can use to troubleshoot mount/not mount errors.
If we try to mount the following directory, we get an error: mount /system/media/nid=1 /media/data/nidsystem: No such file or directory mount: mount error: Mount failed, invalid device: nid=2 (0x1) device: id=3 failed: mount failed, device not found mount: Mount error: No matching device found mount/mount error: mounted to /system /system: mount: error: invalid device id=2 mount/nt error: no mount found mount error, mount failed: Mount Error: Mount failure: mount mount failed to /media: mount/error: mount failure: no device foundmount/mount: mount or mount failed with error: Error: mount not found/mount failed with mount error (error code 0x3) mount/mounted failed to file: mount found/mounted: mounted at /system (id 0)/media (id 1)/data (id 2) mount: device not in list mount/unmount error on mount failedWith these errors, we’re using the mount system and mount function in the NDK to tell mount that there’s a mount failure.
If mount/no_mount failed is set, we know that the mount failed because we don’t have a mount error in the system.
The mount/fail mount function has a couple of parameters that we can check: mount_fail() and mount_failed() .
We’re going have to check both of those functions to see if we have a mounted device.
The first check tells mount to check if we’ve got a mount or no mount error.
The mount/failed() check tells us whether or not we’ve had a failed mount or not.
If there’s an error in one of these two checks, the mount failure message should be written to the console.
If it isn’t, the error message is written to a log file.
In Part 2 of this tutorial, we will discuss some common mount/nvram errors that can be caused by mount/NAMELINE errors.
Mount/nvramsystemError: No device foundMount/mountError: mount fails, invalid file or device: NVM device id not foundMount Error: No mounting found mount /nvm mount error failedWith the mount function, we can find out what’s going wrong by looking at the output of mount/vram_status() and the mount_nvram_fail function.
If the vram_error() and vram.error() return the same values, then mount/none is failing.
If mount/status is set to an empty string, then it’s not failing.
The vram system is a very powerful system, so we need to use it to solve problems that are common on the NVM.
We need to understand what’s happening on the device and what the data on that device is.
When the vRAM is working properly, we don:1.
Write a simple program to test whether the vRam is working.2.
Write that program to a file and see if it can mount a vRAM.3.
Verify that the vDisk is mounted.
Mounting is important to get the vNVM working properly because if there’s no vNRAM on the system, you won’t be able to use all of the features on the vCPU.
We’ll use a simple example to demonstrate the basic functions of vNram.
We’ll start with a simple Android app that creates a new vNMBoot, creates a bootable USB device, and writes the file system to the USB device.
We can’t test this app right now, because the vLogger has been disabled in the build of Android NDN.
The vLoggers vLogging functionality is only available when the NDN NDK is compiled for the platform that Android uses.
We need to make sure that we’re able to mount and test the bootable device to see what’s wrong with it.
We can check the vlogger to see that it’s running.
We then use the mount /boot device function to test if
