Is there a workaround for automatically logging out when building Yocto BSP?

[bskimaaa]

Create an Ubuntu VM environment to build Yocto BSP 

If I did the same as above site,
When I ran the "bitbake fsl-image-qt5-validation-imx" command,
Only when BB_NUMBER_THREADS = "1" in conf / local.conf,
The build could be completed.

BSP : L4.14.98_2.0.0 for Linux Yocto BSP

BOARD : MCIMX8M-EVKB

I've tried OS ubuntu 16.04, ubuntu 14.04, ubuntu 18.04
Etc. are all the same result.

If BB_NUMBER_THREADS is greater than 1,
vmware Linux will be logged out automatically.

I used up to 32GB of memory and used up to 16 cores.

The build will complete successfully only if BB_NUMBER_THREADS is 1.

The build takes about 9 hours.

It takes too long to use this.

Is there any way to solve this?

I have experienced the same symptoms.
You have successfully built yocto by connecting to the network, not logging main screen.

Hi Byung,

    I often use 4 cores to compile yocto bsp, I also tested 6 cores, which is also no problem.

Have a nice day!

Hello Byung,

   

Since your PC has 16 cores, you can set CPU number to be 8 cores here.

Then when you start to build yocto BSP,  8 tasks will be performed at the same time.

Have a nice day!

Thank you for your reply.

As you said, If you configure as above and build, 8 tasks build approximately 4000 jobs at the same time

and log out automatically.

I tried using 2, 3, 4, 8, 16 cores.
After building everything, ubuntu linux will automatically log out.

FYI my PC has 16 cores.
