Generated system.img not running on emulator

Question

I wanted to build a custom ROM for Android TV.

I have followed the steps given on the Android Source Code - AOSP website and downloaded the source using the commands below:

repo init -u https://android.googlesource.com/platform/manifest -b master
repo sync -j16 -c

source build/envsetup.sh
lunch aosp_x86-eng

To build the system image, I am using the following command:

make -j16

It is using the latest Q release to build:

PLATFORM_VERSION_CODENAME=Q
PLATFORM_VERSION=Q
TARGET_PRODUCT=aosp_x86
TARGET_BUILD_VARIANT=eng
TARGET_BUILD_TYPE=release
TARGET_BUILD_APPS=LiveTv
TARGET_ARCH=x86
TARGET_ARCH_VARIANT=x86
HOST_ARCH=x86_64
HOST_2ND_ARCH=x86
HOST_OS=linux
HOST_OS_EXTRA=Linux-4.4.0-130-generic-x86_64-Ubuntu-16.04.4-LTS
HOST_CROSS_OS=windows
HOST_CROSS_ARCH=x86
HOST_CROSS_2ND_ARCH=x86_64
HOST_BUILD_TYPE=release
BUILD_ID=OC-MR1
OUT_DIR=out

The build is always successful. system.img and ramdisk.img are also generated.

I wanted to test the system image on an emulator. I used the command below:

./emulator -avd tvrom -sysdir out/target/product/generic_x86/ -system out/target/product/generic_x86/system.img -ramdisk out/target/product/generic_x86/ramdisk.img -data out/target/product/generic_x86/userdata.img -kernel prebuilts/qemu-kernel/x86/kernel-qemu

The avd name is tvrom and the other parameters are paths to the system images that I have built.

But, after doing this, system.img is not booting in the emulator and it remains a black screen there.

Also, there is an error printing in terminal:

Segmentation fault (core dumped)

I searched for it, but didn't found any solution. Can anyone please help?

EDIT

If someone provides a list of steps to flash and boot the latest AOSP_X86 or AOSP_X86_64 customized ROM on Android Emulator, then it will be useful.

Are you using `repo sync` to download sources? If you are, you need to mention the version as a parameter. — Susmit Agrawal, Jul 16 '18 at 09:59
Sorry, I mean `repo init`. You need to specify the android version here. Check this link for more info: https://source.android.com/setup/build/downloading — Susmit Agrawal, Jul 16 '18 at 13:54
@SusmitAgrawal Please see updated question. I have also put bounty on the question. — krupal.agile, Jul 19 '18 at 09:34
Does the emulator run with other images? Like ones that are provided in Android Studio? — Susmit Agrawal, Jul 19 '18 at 11:13
And if it does, the only thing I can think of right now is using `lunch goldfish` instead of `lunch aosp_x86-eng` — Susmit Agrawal, Jul 19 '18 at 11:15
@SusmitAgrawal What is the difference between two? I am novice in custom roms. — krupal.agile, Jul 19 '18 at 11:34
@SusmitAgrawal Yes, It is only running with provided images in Android studio. — krupal.agile, Jul 19 '18 at 11:36
`goldfish` is the official device code for the Android Emulator. `aosp_x86-eng` is a general image for any x86 based device (eg. Your laptop). Truthfully, I've never been able to get the latter to work in any of my tests. — Susmit Agrawal, Jul 19 '18 at 11:37
@SusmitAgrawal I am getting error running that: build/make/core/product_config.mk:229: error: Can not locate config makefile for product "goldfish". — krupal.agile, Jul 19 '18 at 11:39

Were you able to get a fix ? i am trying to just extract an image and rebuild it and it won't run — Ankit Srivastava, Sep 08 '19 at 20:37
