=== `fastboot oem getlog`
|
|
|
|
This is the first device, and possibly the only device, known to ship with the
|
|
`oem getlog` fastboot command.
|
|
|
|
This is not a trivial command to use, but it is extremely useful as it allows
|
|
side-stepping the need to boot in a known working system to use the ramoops
|
|
console.
|
|
|
|
The output of the command is a jumble, but is still usable for figuring out
|
|
early boot issues. It is much better than having to rely on a booted system to
|
|
get the information, but still not as good as having a dedicated serial access.
|
|
|
|
Example usage follows.
|
|
|
|
```
|
|
$ fastboot oem getlog 2>&1
|
|

|
[...]
|
|
```
|
|
|
|
As the output of the command is on stderr, here's how to output to a file.
|
|
|
|
```
|
|
$ fastboot oem getlog > log.txt 2>&1
|
|
```
|
|
|
|
It is unknown if there are ways to make the output better.
