fetch error during demo-image-sato build, kirkstone branch

[hutcruchi]

Hi,
I'm trying to build demo-image-sato and getting a fetch error during bitbake execution (I followed the instructions in the tegra-demo-distro README)

terminal.log:
terminal.log

error.log:
log.do_fetch.907290.log

Thanks

From the do_fetch log:

Resolving deltas:  80% (5377655/6694800)
error: index-pack died of signal 9
fatal: index-pack failed

Signal 9 is SIGKILL, so something killed one of the git subprocesses.

I don't know who and why but I noticed my Ubuntu hanged sometimes. Maybe the OS killed one of the processes?

1. Can I limit the resources used by bitbake build in order to prevent system hang? (build slower)
2. Can I build again without building everything from start, just what is missing? (to build faster)

Thanks

There are some variables you can set to limit parallelism if your build host is short on resources. This section of the Yocto Project documentation mentions them. By default, the bitbake sets the parallelism variables based on the number CPU cores/threads available. It's generally recommended to have at least 1GiB RAM available per core/thread, IIRC.

The build system already has built-in mechanisms for avoiding unneeded rebuilds of packages. I'd really recommend visiting the Yocto Project web site for more information about the build system, host requirements, etc. The on-line documentation is well-maintained, and you'll also find links there to books, presentations, and training.

Thank you for your answer.
I verified with dmesg it was indeed a memory issue , hence the SIGKILL.
I used the variables you mentioned.
Regarding reading all the learnning sources - I'll do it. I try to "quick start" with the tegra demo and than I'll dive deeper.
If you have any recommendation regarding specific practical tutorial it will be much helpful (there is a lot information out there).

hlo @hutcruchi how did you solved the problem ? I am also fasing the same issue like you got.
I am new to this Yocto project could you tell the steps for building the images for orin devkit board ?
where to find the .sdcard image ?
That would be great help to me .

Thanks and regards

See https://github.com/OE4T/tegra-demo-distro for step by step build instructions with a demo distribution and https://github.com/OE4T/meta-tegra/wiki/Flashing-the-Jetson-Dev-Kit for flashing instructions.
