adb during boot

[Droid]

Iam trying to port android to my embedded board and it restarts surfaceflinger and loops everything after it starts bootnimation. So, to debug this further i am trying to enable adb so that i can look into logcat. But, when i try to list adb devices on my host PC , i am not getting any devices. Below is my Bootlog and init.<hardware>.usb.rc. Any inputs on how to debug further will be really helpful. Thanks in advance.

adbd on the board might not started yet.

Hello Droid,

You are getting some issues and display is not completed. So some services are not run correctly. Abd need to wait for some state to trigger. So if you have console, please run command "logcat" and find out debug messages of your current issue.

Hi Kha,

To my bad, the serial console is printing logs but it stopped taking inputs as and when it starts booting android. Also, the surfaceflinger restart is happening in loop continuously. 

BTW, do you know when does adbd service triggers during boot? I checked the .rc files and i see i set all required props for trigger to happen except ffs.ready.

Is there anyway that i can get adbd starts before bootanimation service starts.?

Thanks

Droid

Hi Droid,

Are you using user build? Is it right?

Please try to build userdebug or eng to get console. With userdebug or eng build, you can easily type your command in console. Please try to lunch your combo as userdebug instead.

Regarding adbd start, I may check and share you my investigation soon if any luck..
Regards,
Kha

[Droid]

Hi Kha,

Really appreciate your response on this.

I am already using eng build but can give a try with userdebug as well. Will try and let you know.

On adbstart yeah, let me know once you have something.

Thanks,

Droid.

Hi Droid,

I have not checked adb trigger yet.
But I want to confirm 1 Point:
You said that you couldn’t control your terminal with eng build.. Which tools did you use to get kernel log?

If you use Minicom, please try to disable hardware control flow. Hope it can help you....

To disable “Hardware control flow”, you can refer instruction here: https://www.acmesystems.it/minicom

Regards,
Kha

[Droid]

Hi Kha,

I use minicom and hardware flow control was disabled but still same behavior, I am getting uart prints but its not taking my inputs from keyboard.

Do i have to do anything in init scripts for the uart to work?

Thanks,

Droid

[Droid]

Hi,

I am still not able to get serial inputs working, I am getting all the output logs on my terminal but its not taking any inputs. 

Any suggestions on how to debug this further?

Thanks.
