Troubleshooting
|
|
===============
|
|
|
|
This document contains common issues related to the balena CLI, and how to fix them.
|
|
|
|
### After burning to an sdcard, my device doesn't boot
|
|
|
|
- The downloaded image is not complete (download was interrupted).
|
|
|
|
Please clean the cache (`%HOME/.balena/cache` or `C:\Users\<user>\_balena\cache`) and run the command again. In the future, the CLI will check that the image is not complete and clean the cache for you.
|
|
|
|
### I get a permission error when burning to an sdcard
|
|
|
|
- The SDCard is locked.
|
|
|
|
### I get EINVAL errors on Cygwin
|
|
|
|
The errors look something like this:
|
|
|
|
```
|
|
net.js:156
|
|
this._handle.open(options.fd);
|
|
^
|
|
Error: EINVAL, invalid argument
|
|
at new Socket (net.js:156:18)
|
|
at process.stdin (node.js:664:19)
|
|
at Object.Interface.createInterface (C:\cygwin\home\Juan Cruz Viotti\Projects\balena-cli\node_modules\inquirer\node_modules\readline2\index.js:31:43)
|
|
at PromptUI.UI (C:\cygwin\home\Juan Cruz Viotti\Projects\balena-cli\node_modules\inquirer\lib\ui\baseUI.js:23:40)
|
|
at new PromptUI (C:\cygwin\home\Juan Cruz Viotti\Projects\balena-cli\node_modules\inquirer\lib\ui\prompt.js:26:8)
|
|
at Object.promptModule [as prompt] (C:\cygwin\home\Juan Cruz Viotti\Projects\balena-cli\node_modules\inquirer\lib\inquirer.js:27:14)
|
|
```
|
|
|
|
- Some interactive widgets don't work on `Cygwin`. If you're running Windows, it's preferrable that you use `cmd.exe`, as `Cygwin` is [not official supported by Node.js](https://github.com/chjj/blessed/issues/56#issuecomment-42671945).

|
|
### I get `Invalid MBR boot signature` when configuring a device
|
|
|
|
This error, accompanied with something like: `Expected 0xAA55, but saw 0x29FE` usually indicates a corrupted device operating system image in the cache, due to bad a internet connection during the download process.
|
|
|
|
Try clearing the cache with the following command and trying again:
|
|
|
|
```sh
|
|
$ rm -rf $HOME/.balena/cache
|
|
```
|
|
|
|
Or in Windows:
|
|
|
|
```sh
|
|
> del /s /q %UserProfile%\_balena\cache
|
|
```
|
|
|
|
### I get `EACCES: permission denied` when logging in
|
|
|
|
The balena CLI stores the session token in `$HOME/.balena` or `C:\Users\<user>\_balena` in UNIX based operating systems and Windows respectively. This error usually indicates that the user doesn't have permissions over that directory, which can happen if you ran the balena CLI as `root`, and thus the directory got owned by him.
|
|
|
|
Try resetting the ownership by running:
|
|
|
|
```sh
|
|
$ sudo chown -R <user> $HOME/.balena
|
|
```
