Here's how to use logcat:
There are two main ways to do a logcat, within android, and through adb.
Logcat within android can be done one of two ways, through a Logcat app:
Here are two good examples are either: aLogcat or Catlog
I prefer catlog, because in my opinion it has a little bit nicer UI. Both of these programs can dump their logs to a txt file, which is very useful for debugging. Or, you can do it in terminal emulator (same rules as running through adb(see below))

Remember, Logcat will run till you end the session. And it won't always create the file till you do so. It's possible you may not see the logfile for a minute or so.
Edit: For phones/tablets with internal storage & external sd:
(note that the location naming convention may be different depending on device)
Open your terminal app;
Type: logcat > /sdcard/logcat.txt (this should create it in internal memory on the tablet)
To send to ext sd card: logcat > /mnt/external_sd/logcat.txt
I use a tablet for example Phones may have a different naming convention.

On the other hand, using adb to run logcat, in my opinion is much more useful, because you can start using it when android boots (i.e. once the boot animation appears.)
The code for logcat to output to a file is
Code:
adb logcat > name of problem.txt
you can also do
Code:
adb logcat -f name of problem.txt
how I prefer to do it is this way:
Code:
adb logcat -v long > name of problem.txt
with the -v flag & the long argument, it changes output to long style, which means every line of logcat will be on its own line (makes it a little neater, imo)
Note: When outputting to a file, you will see a newline, but nothing printed, this is normal. To stop logcat from writting to a file, you need to press ctrl+c.
Here's where using logcat (via adb makes life really easy)
Lets say you find a problem you're having after looking at a logcat.
For example:
When I was trying to use a different ramdisk, wifi wouldn't work so I got a logcat that's almost 1300 lines long (a lot of stuff happens in the background)
So if you are searching for an error in the logcat file (it's always e/ for error, f/ for fatal. Those are the two main things that will break a system.)

(mind you, that's 29 lines out of 1300ish, just for example)
I then could do the following with logcat:
Code:
adb logcat WifiStateMachine:E *:S -v long > name of problem.txt
and this will only print out any errors associated with WifiStateMachine, and anything which is fatal, which makes it about a million times easier to figure out what's going on!
In WifiStateMachine:E, the :E = to look for Errors, the full list of options is as follows:
V — Verbose (lowest priority)
D — Debug
I — Info (default priority)
W — Warning
E — Error
F — Fatal
S — Silent (highest priority, on which nothing is ever printed)
You can replace the :E with any other letter from above to get more info.
In order to filter out anything other than what you are looking for (in this case, WifiStateMachine) you must put a *:S after your last command (i.e. WifiStateMachine:E ThemeChoose:V ... ... AndroidRuntime:E *:S)

Very nice, but I do have a question (and I started programming for Android recently): What do you do when the system reboots while debugging (in my case musb_hdrc.ko)? I tried catlog, but the logs are empty... Is there another way to do that?
Thank you in advance

Use adb instead of an in-android method to capture the logs, you can start when the boot animation starts (note: Not when the kernel splash screen appears) and when it reboots, it'll automatically end. (i.e. run the following in command prompt:
Code:
adb logcat *:E > oh_nos_it_crashed.txt
)
If you're not getting to the boot animation (keeps cycling on the Kernel splash screen) then you have kernel issues, and you need a kernel that has integrated last_kmsg (a whole different ball of wax that I'm still learning about) to figure out what's going on. (kmesg's are direct kernel output)
Maybe if someone like AdamOutler (or any other Dev who has a much better handle on them than myself) were to explain them, it'd help

Hey man regarding your guide .
I was testing a built of cm9 from my htc one v and it wasnt booting so the dev told me to do a logcat for it .
Just wondering what the process and commands would be?
Thanks.

Remember, Logcat will run till you end the session. And it won't always create the file till you do so. It's possible you may not see the logfile for a minute or so.

What you'll wanna do is run the following,
Code:
adb logcat *:E > crash.txt
And look at the output file specifically for lines that say 0x0deadbaad (if you see that, that means there's a problem with the Java libraries it references above it) otherwise look for other F/ lines, that'll point you in the right direction.
If you're having issues where and is not accessible for to buy having USB debugging turned off because of doing a /data wipe (factory data reset) first install a similar Rom (in your case, a prior, stable CM9, boot into it, turn on usb debugging, reboot into recovery & only write /cache & dalvik cache before installing the offending Rom & getting your logcat (sorry if I rambled, just got done working a double )

The problem is when you can't access terminal (bootloops, fc'ing like it's going out of style, etc.) that adb is really useful. Sometimes to trick the system into working, you can (esp with AOSP based roms) install a same version of android (I.e. 4.0.4) & not wipe /data (after turning on usb debugging) & still have an access (I learned this after spending about 2-3 months crack flashing my own builds & getting tired of titanium restoring all my apps)

Why would you want to do that?
To my knowledge, the only way logcat is reset is if you reboot your phone.
That's why filtering your results is very helpful, because no matter how long it's been running, you can get the info that you want without extraneous information
Pax
Thanks for the clarifications
Man thank you so much for the awesome guide!
Now I can actually filter out my logcat results instead of searching through the entire log.

FIXED HUGE ISSUE CAUSING EMPTY FILES
DOWNLOAD
PM or post here if you run into any issues. They WILL be addressed.
I have made a tool to simplify Logcat creation for people. The creation of this tool was inspired, and guided, by the thread started HERE by paxChristos.
UPDATE 4.1
Corrected an issue causing empty files.
apparently, if the process id contained a space ( 1234) the file would parse correctly, but if the numbers came up to the parenthesis (12345) it would output an empty file named ACTIVITY(12345) with no extension.
This was a huge issue, and i apologize for not seeing it sooner. It has been corrected, and the logcat tool works better than ever. I just ran through a 20,000 line logcat without any empty files appearing.
a couple more things to help with stability.
Underscores (_) will be replaced by dashes (-)
Brackets ([]) and arrows (<>) will be replaced with paranthesis(())
-------------------------------------------------------------------------------------------------------------
HUGE UPDATE
Added the ability to "SUPER PARSE" Files, which separates files into folders by log level and creates a TXT file for each activity
Super parse DOES NOT Work with LONG format Logs.
SUPER PARSE is in its infancy I do expect errors, please let me know if you run into anything.
OLD STUFF
EDIT V3.6 DONE
Added ability to filter logcats by activity name. (logcat -s "FILTER")
Fixed Log Level Setting
EDIT V3.5 DONE
NOW PROPERLY PARSES "LONG" FORMAT LOGCATS.
Thank you to Senior Member jes0411 for pointing out the issues that lead me to create V3.4 and 3.5. If any of you have an issue please let me know. It could be hours before i get to it or weeks, but i will get to fixing it.
EDIT V3.4 DONE
Changed the way the date variable was handled to hopefully fix issues experienced by users of non-English versions of windows.
EDIT V3.3 DONE
EDIT V 3.2 Finished
Google code won't allow any new uploads, so i uploaded the new update to XDA in a ZIP file.
Fixed ADB Location settings, some users were having trouble if they input the ADB folder with any quotation marks in the path name, it will now automatically remove quotation marks to ensure correct syntax.
Fixed issue with ADB Location setting not exiting to previous menu.
Fixed issue with Log Level setting not exiting to previous menu.
Capitalized some stuff
Added a feature that will automatically create the selected folder if no output folder exists and the user attempts to run a log.
Added a check when selecting an output folder that will ask if you want the folder created if it does not exist
EDIT V3.1 DONE
FIXED OPTIONS 7 & 8, URLS WERE MISSING A "?"
CHANGELOG EDITS
SAVES AND PARSES FILES IN TO DIFFERENT OUPUT FILES BASED ON LOG LEVEL (E , I , D , W , ETC)

It took me about one week to port cwm recovery to coolpad 5310, which build on msm8610 according to the default.prop.
I'd like to share my experience and code here if anybody need it.
First, I began with this guide:
http://xda-university.com/as-a-developer/porting-clockworkmod-recovery-to-a-new-device
It's very clear, but with a error. I should type
Code:
lunch cm_<device name>-eng
instead of
Code:
lunch full_<device name>-eng
. I guess that the information needed being updated.
It was definitely worth notice that I pull the cm-10.2 instead of cm-11 for my phone coming with Android 4.3.1. I think with same version the CWM recovery may be easier to port.
Then I flashed the img file to my device with fastboot. But when I reboot device into recovery, the phone did it but reboot again to android. It's tough because I have no idea how to debug.
Luckily, when I try
Code:
fastboot boot <recovery img>
by accident, I find following information:
Code:
FAILED (remote: dtb not found)
After a google, I find mkbootimg_tools and repack the recovery I compiled with the img.dt from stock recovery. The kernel and adbd boot!
But there was nothing on my screen. I found the recovery program exited with segmentation fault. So I explore the /tmp/recovery.log and compare it with log file from stock recovery. I found following info in my recovery.log:
Code:
ERROR: failed to mmap framebuffer
and there was no framebuffer info in my recovery.log.
After reading code, adding debug info in code and googling information about msm8610, I almost got the reason. Qualcomm do something strange and we could no operate /dev/graphics/fb0 directly. I have no idea how to resolve it.
Then I find this discussion, and cover it. The problem is so alike, but I cannot still resolve my problem until I found there is no file named graphics_overly.c in my code tree. Finally, I found it in code tree of cm-11.0, then I checkout to cm-11.0 and built it. The recovery program run well.
There is two thing worth noticing. Firstly, I'm sure the only variable taking effect is TARGET_USES_QCOM_BSP := true after reading the code. Then, adding --dt dt.img to BOARD_MKBOOTIMG_ARGS could avoid repack the recovery.img any more.
The final problem is that my /sdcard is symlinked to /sdcard so I could not mount sdcard on it. I have fix the bug and now I'm trying to post the patch to upstream(Cyanogenmod): http://review.cyanogenmod.org/#/c/80390/
There is some files:
The project on my github.
The recovery.img, it's fast in China, but maybe slow in other countries, so I also upload it as an attachment.
Has anybody figured out how to get rid of the Bootloader Unlocked warning when booting this phone? It certainly slows down the booting process.
I haven't figured it out yet. To be honest I've been trying to figure out what apps are safe to uninstall and a custom ROM or how to update to Android 12. But I'll definitely let you know if I figure a way out.

So the --dtb should be --recovery_dtbo I believe. Not sure where this command is being generated in order to fix it.
I was running into problems like that I factor rest it and turned it off. Where did you compile the boot.img from? And ya it would work better if it was trying to go to the right path. I had to find a boot.img from one of the over seas ones I kept getting it were it would root but the screen did respond.

I could be wrong but the recovery I'm using (orange fox) does use a kernel_dtb. So it seems your recovery image kernel doesn't have the right path to the dtb binary it needs. Try searching the build directory for any _dtb/.dtb and rename accordingly. I'd you need to alter the dtb from a related SoC there are tools for unpacking and modifying those.
The recovery and boot ones would be similar I imagine since those files are a map of the device's hardware.

I used the same one to create my magisk boot.img as well. I used dumpyara to build the device tree using the above file for my source which seemed to work properly. No errors in other words.

I just recently had to deal with all this crap because I didn't know GPD changed which revision of the mediatek SoC they used in the GPD XD while keeping the serial numbers the same. Flashed my old one's backup on it and half the cores were stuck offlined when it booted up. Ended up having to get ahold of the stock kernel for that board revision and patch in the correct dtb for that SoC.
I don't have links but some of the sites that delve into generic Linux kernel porting have tools for decompiling kernel_dtb files to an editable form that you can then recompile if you do have device/driver issues. Also the magisk module for enabling TWRP sdcard storage backups has some Android arm64 native binaries in it that can help with tearing apart kernel/recovery images. (They both are technically kernel images, just one boots a minimal OS).
Edit: I think any dtbo files would be individual compiled object files that get linked into the final dtb image.
Edit 2: I just saw your other comment above. Congrats, that sounds like a viable (and probably long term stable) way you found.
On another topic, I have been trying to mount /system as r/w (thru adb). It appears /system is not actually a mount point but under a different mount point. Any idea what that might be? Doing a cat on /proc/mounts yeilds a crapload of mounts, with many belonging to magisk, but no /system.
I know its been 4 month since last activity, but has there been any progress on this?
There does not seem to have been much progress on this, but I read somewhere recently that the G Stylus (2021) was either the most popular or best-selling Moto phone in 2021. Who knows if that is exactly true, but if it is indeed so popular, here's to hoping that some capable developers will take an interest in it eventually!
Several folks have mentioned that loading a GSI (Generic System Image) should be possible, but I have not had any extended downtime myself to be able to try this. But if you do, you can find some guidance for the 2020 version of the G Stylus at:
https://forum.xda-developers.com/t/...ic-system-image-on-the-moto-g-stylus.4131199/

Am I supposed to check out the sources from Google or Lineage and merge them into Evo?
Trying to build AOSP from Google results in a bunch of timeouts and the odd 404.
Lineage wants to pull the blobs from a running phone on Lineage or pull them from a build.zip but that doens't work either.
Python 2 is depreciated for years, but somehow Android still "needs" it? Why?!?!?!
There is no target for python2 in the repos anymore, but I have the last build installed anyway - still no love.
Suggestions?

Seemingly no matter what repo I try to build from, it's never successful.
Here's the output trying to build Evo:

You are missing at least one repo, if not more, I don't know anything about Evo. I'll provide some input to what's quoted above though, first, this is your current issue:
hardware/google/pixel/touch/device.mk: No such file or directory
Check where that repo is coming from, if it's AOSP, change it
Has anyone successfully built Android on Arch?
The distro used to build isn't relevant, as long as all dependencies are there
Lineage wants to pull the blobs from a running phone on Lineage or pull them from a build.zip but that doens't work either.
My guess is you're doing it wrong, or it's back to making sure you have all the dependencies required, because it does in fact work.
Suggestions?
If you've done this before, like "Back in the day" or whatever, then you'll need to catch up with how things are done "Today".
This was all a lot easier just a few years ago...
Ok so I finally made some progress.
I have a working build environment on Arch for AOSP however trying to build Evolution-X fails because
Code:
. build/envsetup.sh
doesn't work correctly - the path doesn't change for the build aborts because it can't find yaml.h since the build paths don't get set up.
The exact same repo builds on Ubuntu 23.04 though.
Main differences are Ubuntu is using bash, I'm using zsh in Arch (EndeavourOS) but I've tried running it in bash and the same issue is present.
Weird is AOSP's envsetup.sh works properly for AOSP.
Any ideas?
I don't like Ubuntu anywhere near as much as Arch and it's derivatives...
My next idea is to make a new user account with stock config vs my well worked in zsh setup and environment.
EDIT: that didn't work, either.
Another difference is my EndeavousOS install is in French, Ubuntu is installed in English. Would that cause an issue?
