Hi ，ti expert

Dose ADB(Android debug bridge) full functions(Client, Service, Deamon) supported in SDK 7_0_1?

If not, could you help to support ADB functions?

thanks

Hello,

As the definition says adb is for android and not for Linux sdk(the daemon and client tools are all on Android os eco system).

1. Can you provide more information on the purpose and usage of such capability on linux?.

2. What is the target device.

If you are looking for debug capability, you can get the serial log from the evm.

Adb underlying uses USB gadget mode. Such USB functionality as gadget mode should be present in Linux sdk.

If the purpose of adb is something else, please provide more details.

Hi,

We'll disable serial port when product release. ADB is need for debug(logcat..etc) and many other operations.

Hi Difei Ding,

I understand your requirement but unfortunately ADB is not going to be supported on Linux SDK. You will have to add this by yourself if this is needed for your project.

Hi Difei Ding,

We haven't worked on adding adb support on the Linux SDK so far, it has never been a requirement.

This is a long shot and it hasn't been tried on the TISDK, you can start with rebuilding the Yocto filesystem by including the "android-tools" recipes. It is located under "./meta-openembedded/meta-oe/recipes-devtools/android-tools/android-tools_5.1.1.r37.bb"

This may be the starting point for you to explore further.

Hi Karthik,

ADB host is work now. But adbd no function.

I think we shoud add usb_composit_driver for adbd in kernel, right?

Could you help to provide any documents or comments for how to use configfs and usb_composit_driver?

Hi Difei Ding,

We don't have any document for USB configfs steps.

For reference you can look at Google (Android) kernel config options to see what they enable in kernel for configfs functionfs
https://android.googlesource.com/kernel/configs/+/refs/heads/master/android-5.4/android-base.config

And on the user space side, below files can be looked for reference
* android.googlesource.com/.../init.beagle_x15board.usb.rc
* https://android.googlesource.com/platform/system/core/+/refs/heads/android10-dev/rootdir/init.usb.configfs.rc

Vishal
