Compiled Latest Vim2 Source From Scratch - Fails to Boot

byob11 · October 31, 2017, 4:10am

I just downloaded the latest source code and compiled it from scratch on two different machines. I apply the resulting “update.img” on my Vim2 v1.2 hardware using USB Burning Tool v2.1.2. Everything appears to be fine and normal. When I reboot, the Vim2 is stuck on the “KHADAS” bootup bitmap image. It’s stuck here and doesn’t go on to the bootanimation.zip process.

If I download the firmware from your website, everything works fine. What am I missing?

Steps:

Vim2 MAX
v1.2 Hardware
Latest source code:
– repo init -u https://github.com/khadas/android_manifest.git -b Nougat
– repo sync -j4
Compiled Successfully:
– source build/envsetup.sh
– lunch kvim-userdebug-64
– make -j12 otapackage
Copied “update.img” to Windows PC
Applied “update.img” to Vim2 via Amlogic USB Burning Tool v2.1.2
Successful flash
Reboots
Stuck on “Khadas” bootup bitmap image for hours.

It seem that you compile the VIM1, should be kvim2 instead.

Hi,

you also need (I think, so I always do) to build U-boot before main build.

Also you don’t need windows to flash, just copy kvim2-ota-{date}.zip to usb stick (fat32 formated) or micro sdcard if you have it and flash it over recovery console.

I believe if you forget to build uboot first, Android build will fail as there will be image missing when update.img is being generated.

Thanks everyone!! I truly appreciate your help!!! It would appear I followed the directions to the LETTER (which was the wrong thing to do )

First, did I understand this correctly:

lunch kvim-userdebug-64 needs to be lunch kvim2-userdebug-64?

Next, I definitely built the u-boot first. However, I’m starting to doubt that I did that correctly now. Here is what I typed:
make CROSS_COMPILE=aarch64-linux-gnu- kvim_defconfig
make CROSS_COMPILE=aarch64-linux-gnu-

Sounds like this should have been this?
$ make CROSS_COMPILE=aarch64-linux-gnu- kvim2_defconfig
$ make CROSS_COMPILE=aarch64-linux-gnu-

Correct?

BTW - thanks ssehovic for the tip regarding the OTA package. I’m so familiar with modifying the firmware images that I’ve downloaded that I forget there’s an easier way. As you can tell, I’m new to compiling the source code. But, I’m reading and learning.

Finally, I hooked up a serial interface and captured the log. It looks like everything goes pear shape after the Kernel starts “Unpacking initramfs…”. I compared my log to a working firmware log.

I will try all new suggestions now and let you guys know my progress.

Thanks again!!

Hi,

that is why I wrote this little helper script to build vim2 from source.

github.com

ssehovic/utils/blob/Nougat/vim2_N_build.sh

#!/bin/bash

clear

echo -e "\nSimple script to automate build of Android Nougat (7.1.x) for VIM2 on linux box"

Your’e not lazy … you’re working smarter, not harder!!

I’ve followed your script’s instructions. I’m not able to compile the source code now. It fails every time I’ve tried to compile it on two different machines. The latest error:

ERROR: /home/epitirodev/proj/vim2/frameworks/support/compat/kitkat/android/support/v4/os/EnvironmentCompatKitKat.java:0: The type android.view.View cannot be found in source files, imported jack libs or the classpath

ninja: build stopped: subcommand failed.
make: *** [ninja_wrapper] Error 1

make failed to build some targets (06:02 (mm:ss))

Thoughts?

Thanks again!!

Hmm strange I have no problem with it. I am on arch linux.
Maybe you are missing libicui18n lib?

Edit: here

my installclean build.

Thanks again for all of your support. I was finally able to get it to compile this morning. The only thing I did differently is to:

Use 7GB RAM for Jack Server -1GB from 8GB

export JACK_SERVER_VM_ARGUMENTS=“-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx7000m”

Killing…

out/host/linux-x86/bin/jack-admin kill-server

Starting…

out/host/linux-x86/bin/jack-admin start-server

I then did a:

make clean

Command followed by:

make -j4 otapackage

Previously, I was using -j8 and -j12 (which worked for me before).

I’m not sure what’s going on. It appears that the make process for the VIM2 is extremely particular and brittle. Thoughts on something else I could have been doing wrong?

Thanks again!!

I can’t compile Vim2 on my Ubuntu 16.04.3 LTE machine at all. It keeps crashing at the same spot (5%). Thoughts? Here is the error message:

[ 5% 2739/50828] host C++: libart <= art/runtime/gc/accounting/mod_union_table.cc

Maybe you must use older python on your build machine.
As you can see from my screenshoot I am using virtual environment with python 2.7something as with latest python 3 I can’t build.

byob11 · November 3, 2017, 2:23pm

I rebuilt the machine as 14.04 and this fixed my problem. I’m all set. Thanks ssehovic! You were a huge help. I appreciate your time.
