how to setup bitbake environment without rebuilding from scratch about meta-riscv

@pino-kim

1. I think ...you'd better make some bash script to change local.conf in build/conf when set environment.

As you suggested, by commenting the line "rm -f $DIR" works. I was able to setup environment without rebuilding.

-> When you encounter your issue.When set up build environment? or while Running bitbake?
Dmesg log point you something wrong? I guess you attach your system by terminal program(protocal ssh). If true, do you use tmux or screen when set up yocto and run bitbake?

Now everything works fine. Thanks a lot

Hi @sbz-12d

can I join your issue?
At first,I have ask some questoion about your issue.

1. I don't never heard about scratch. So can you give me more information scratch???
   Is a yocto's tool? Or meaniing something? (I understand 'scratch' meanning base. am i right?)

Answer to you question as I known

1. If remove line 11, in setup.sh, build dir will not removed by script.
   

   meta-riscv/setup.sh

   Line 11 in 4157f3e

   rm -rf $DIR

2, 3. I think you should reference auto.conf. when setup.sh run, It well be generated. you can find it /build/conf. Also add meta directory in your bblayer.conf.

your host build system is look fine to build riscv yocto. I mean enough space.
If you have error log, I recommend you to attach it.

Hi @pino-kim

Thanks for your reply.

   Is a yocto's tool? Or meaniing something? (I understand 'scratch' meanning base. am i right?)

1. "From scratch" in this context means from beginning or from starting. I meant to say that running setup.sh again (already built image) starts the building of the image the from the beginning.

1. If remove line 11, in setup.sh, build dir will not removed by script.
   

   meta-riscv/setup.sh

   Line 11 in 4157f3e

   rm -rf $DIR

2. I will remove " rm -rf $DIR " line from setup.sh and will check it. But currently what i'm doing is, once i have built the image i made a copy of local.conf file from build/conf/local.conf and whenever i want to setup environment for bitbake, i'm doing "source openembedded-core/oe-init-build-env " and copying the backup local.conf file to build/conf folder (replacing the file inside it.). I was able to run the bitbake and build the image without any problem.

If you have error log, I recommend you to attach it.

3. There was no error log generated. since system was abruptly logging out by killing all the processes current user owns. i have checked the dmesg as well.
   3.1 please note that the error is getting generated when i tried to setup bitbake environment to already built image by doing "source openembedded-core/oe-init-build-env " only and running "bitbake core-image-full-cmdline" command.
   3.2 I was also getting the same error when i did . ./setup.sh and did "bitbake core-image-lsb-sdk".

Hi @kraj

It is in build directory only. build/sstate-cache
