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

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?

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.

i.MX8M Yocto Project Bitbake Unexpected Termination

This is the same issue as the above site.

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!
