raspberry pi 4 (rpi4) webOS image building ( pre-built image )

webos raspberry pi 4 image download



여러분 대부분은 webOS 이미지를 구하거나, 빌드를 시도하다가 왔을 겁니다.
i'm sure you came here while LF pre-built img or got failure on building img for rpi3, rpi4.

http://build.webos-ports.org/webosose/

404... you have to build your own img for rpi4.

and if you get

ERROR: Task (/home/user/build-webos/meta-qt6/recipes-qt/qt6/qtbase_git.bb:do_install_ptest_base) failed with exit code '1'

간단히 요약하면 가상머신 쓰지 말고,
리눅스용 윈도우 하위 시스템 쓰지마세요.
그냥 500기가정도 파티션 잡아서 듀얼부팅을 하던 해주세요..
아 근데 노트북 일부 기종은 윈도우만 부팅되게 되어있어서 안되더라구요.

글구 듀얼부팅 한다 쳐도... 안됩니다... 왜 인지는 모르겠어요.

데탑 쓰세요... 진짜 미칩니다. 그냥 데탑이 짱입니다.

try on ubuntu desktop. 20.04.

do not try on virtual machine, wsl , wsl2
18.04, 20.04, 22.04 i tried all that version. and all failed.
i lost more than 100Hrs.

 

 

AND!  

PLZ UPDATE BIOS LASTEST VERSION IF YOU ARE USING AMD's CPU!!!!

STUTTERING WILL BOTHER YOU!!!

bake install USB and set Partition at least 400GB. it takes more than 300GB while building ver . 2.19 devel now.

i recommend

at least 6 core CPU,
400GB + SSD partition, good condition internet network ,

at least 16GB RAM

16GB+ micro sd card.

 

 

 

then check something else,

 

 

$ sudo apt update

//i recommend set mirror link.

$ sudo apt-get update

$ sudo apt-get install python3-distutils

// my teammate said it needed, idk y. XD


$ git clone https://github.com/webosose/build-webos.git
$ cd build-webos
$ git fetch origin 2.19
$ git checkout 2.19


$ sudo scripts/prerequisites.sh




check your cpu cores.

$ cat /proc/cpuinfo | grep "physical id" | sort | uniq | wc -l

$ cat /proc/cpuinfo | grep "cpu cores" | uniq



then,     remember (num of cpu) * ( num of cores ) / 2

$ ./mcf -p <number of physical CPU cores / 2> -b <number of physical CPU cores / 2> <target-device-name>



// cf )

$ ./mcf -p 2 -b 2 raspberrypi4

$ ./mcf -p 2 -b 2 raspberrypi4-64


$ ./mcf -p 2 -b 2 raspberrypi3

$ ./mcf -p 2 -b 2 raspberrypi3-64

//for emulator

$ ./mcf -p 2 -b 2 qemux86  

$ ./mcf -p 2 -b 2 qemux86-64





$ source oe-init-build-env

// turn off all other tasks  before next task


// for  device img 

$ bitbake webos-image


// to clean, 

$ rm -rf BUILD
$ ./mcf.status


//to build dev img 

$ bitbake webos-image-devel


// to clean, 

$ rm -rf BUILD

$ ./mcf.status

my build machine spec
- CPU : amd rizen 2600x
- RAM : 16GB ( 8GB X 2 ) DDR4 3000 MHz
- GPU : NVIDIA GTX 950 2GB
- Storage : Samsung M.2 1TB
- <num of CPUs> for mcf : 3


Device Type : rpi4-64,
Image Type : webos-image-devel
Time : about 15H ~ 16H

for rpi4, u need to unzip " ~.wic.bz2" to "~.wic" first.


then, flash webOS OSE.
https://www.webosose.org/docs/guides/setup/flashing-webos-ose/

Flashing webOS OSE

then, you have to connect display that has same or bigger than 1920*1080 resolution.

( becuz default resoltion setting is 1920*1080 and you might not able to set network setting with smaller one.)

https://www.webosose.org/docs/guides/setup/setting-up-network/

then use putty or mobexterm for ssh connection,

defalt name is "root" .



if you gonna use dual display,


root@raspberrypi4# config="[{\"device\":\"/dev/dri/card0\",\"hwcursor\":false,\"outputs\":[{\"name\":\"HDMI1\",\"geometry\":\"SIZE+0+0r0s1\",\"mode\":\"SIZE\"},{\"name\":\"HDMI2\",\"geometry\":\"SIZE+0+0r0s1\",\"mode\":\"SIZE\"}]}]"; luna-send -n 1 -f luna://com.webos.service.config/setConfigs "{\"configs\":{\"com.webos.surfacemanager.displayConfig\": $config}}"

root@raspberrypi4# config="[{\"device\":\"/dev/dri/card0\",\"hwcursor\":false,\"outputs\":[{\"name\":\"HDMI1\",\"geometry\":\"SIZE+0+0r0s1\",\"mode\":\"SIZE\"},{\"name\":\"HDMI2\",\"geometry\":\"SIZE+0+0r0s1\",\"mode\":\"SIZE\"}]}]"; luna-send -n 1 -f luna://com.webos.service.config/setConfigs "{\"configs\":{\"com.webos.surfacemanager.displayConfig\": $config}}"

cf )
root@raspberrypi4# config="[{\"device\":\"/dev/dri/card0\",\"hwcursor\":false,\"outputs\":[{\"name\":\"HDMI1\",\"geometry\":\"1024x600+0+0r0s1\",\"mode\":\"1024x600\"},{\"name\":\"HDMI2\",\"geometry\":\"1024x600+0+0r0s1\",\"mode\":\"1024x600\"}]}]"; luna-send -n 1 -f luna://com.webos.service.config/setConfigs "{\"configs\":{\"com.webos.surfacemanager.displayConfig\": $config}}"

or just one,


root@raspberrypi4# config="[{\"device\":\"/dev/dri/card0\",\"hwcursor\":false,\"outputs\":[{\"name\":\"HDMI1\",\"geometry\":\"SIZE+0+0r0s1\",\"mode\":\"SIZE\"}]}]"; luna-send -n 1 -f luna://com.webos.service.config/setConfigs "{\"configs\":{\"com.webos.surfacemanager.displayConfig\": $config}}"




cf )

root@raspberrypi4# config="[{\"device\":\"/dev/dri/card0\",\"hwcursor\":false,\"outputs\":[{\"name\":\"HDMI1\",\"geometry\":\"1024x600+0+0r0s1\",\"mode\":\"1024x600\"}]}]"; luna-send -n 1 -f luna://com.webos.service.config/setConfigs "{\"configs\":{\"com.webos.surfacemanager.displayConfig\": $config}}"



then reboot your rpi4

reboot -f

 

 

 

editted date 2023-01-24

OR!

 

You can set display option by editting config.txt in your SD card /root folder.
