Building Marlin For Nexus 5X -- Cannot Flash Build Product To Device.

[American Justice Corp]

Target Device: Nexus 5X

Development Host: Linux, Slackware 14.2, 64-Bit, x86_64 Desktop Hardware.

This posting is regarding installing, (flashing) a "userdebug" build of marlin, (repo sync'd on 21 Sept. 2018), to a Nexus 5X Device, 

that is built unmodified via the "repo" commands, "lunch" and "make droid".

Android Studio, and Platform Tools are installed and up to date. Android Studio has been used successfully to build sample Apps, push them to device,

and run them on device.

The repo folder on the Development Host is sync'd, (as of 21 September 2018). 

After a "repo init" and "repo sync", the lunch menu has 37 items. Item #19 is "aosp_marlin-userdebug"

After selecting "aosp_marlin-userdebug", (#19), from the Lunch Menu, "make "adb" and "make fastboot" work.   

adb and fastboot command line programs,  (whether from Platform Tools,  or after "make adb" or "make fast boot"), work fine for shell access to the device, push, pull, bootloader unlock, and flashing with files obtained from here:

https://developers.google.com/android/images

The commands in flash-all.sh all work fine to successfully flash device with its latest "Factory" image, (Bullhead),  ID: 8.1.0 (OPM6.171019.030.K1, Sep 2018)

Then, running "make droid", (for aosp-marlin-userdebug"), successfully builds the various Target Device Image Files, for Marlin, and puts them in $OUT. (After a Glacial Epoch of Time).

Prior to flashing the device with the Image Files created from "make droid", I tried to flash the device with a Marlin System Image, ID: image-marlin-njh34c.zip from  marlin-njh34c-factory-be914eaa.zip

)

The error message I get is:

fastboot -w update image-marlin-njh34c.zip

--------------------------------------------       

Bootloader Version...: BHZ31b

Baseband Version.....: M8994F-2.6.41.5.01

Serial Number........: 0255046c4c403d85

--------------------------------------------       

extracting android-info.txt (0 MB) to RAM...

Checking 'product'                                 FAILED

Device product is 'bullhead'.

Update requires 'marlin' or 'sailfish'.

So, as far as I can tell, the "build" process works fine, but if the "stock" Marlin image cannot be installed on the device, how can one built

from source be flashed onto the device?

I picked an earlier release, Major Version "7" Because I thought it should work. I will update this post after I try the latest "marlin" and "sailfish" Updates in version "8" and "9"

marlin images are for the Pixel XL, they are not compatible with the Nexus 5x (bullhead).

I understand this now. Thanks. I misunderstood the codename as referring to an Android build, not the device itself. 

This topic can be closed.

Thanks.
