Part Number: SK-AM62A-LP

Hello Team,

I am facing the issue in "Building the SDK with Yocto" using the below-mentioned command and the following link for RT-Linux (PROCESSOR-SDK-LINUX-RT-AM62A — RT-Linux SDK for edge AI applications on AM62A). (Build target "tisdk-edgeai-image")

TI-Link Yocto-Link:-

1) https://software-dl.ti.com/processor-sdk-linux-rt/esd/AM62AX/09_01_00/exports/docs/linux/Overview_Building_the_SDK.html

2) https://www.ti.com/tool/SK-AM62A-LP#included

Command:-

1) git clone git.ti.com/.../oe-layersetup.git yocto-build

2) cd yocto-build
3) ./oe-layertool-setup.sh -f configs/processor-sdk-analytics/processor-sdk-analytics-09.01.00-config.txt
4) cd build
5) . conf/setenv
6) echo 'ARAGO_BRAND = "edgeai"' >> conf/local.conf
7) MACHINE=am62axx-evm bitbake -k tisdk-edgeai-image

Debugging:- 

Why is this "asn1_derive-0.8.7.crate" creating an issue in the "python3-cryptography_36.0.2.bb" recipe file during unpacking. Please check and provide a solution/fix on this issue.

Thanks,

    Your setup steps look good. So this could be a transient build issue, or some build environment issue.

    First, please confirm you are running this on Ubuntu 22.04. Then, are you using Docker or some other virtualization tool like that?

    Second, try completely cleaning out the Yocto build tree by doing a `rm -rf build/*` and re-start the build.

    Third, please try this on a different PC.

    Hi Andreas,

    I am using a higher configuration of Ubuntu 22.0.4 Virtual Machine (VM) for source code setup and build environments.

    From the error logs, it seems that issue with the "python3-cryptography_36.0.2.bb" recipe file during unpacking.

    Please check the above details. 

    I will try your suggestion below and update you.

    `rm -rf build/*` and re-start the build.

    Thanks,

    Nisarg

    Hi Nisarg,

    Your machine poses a similar "problem" for Yocto that I saw on my own machine, which is the number of cores is very high compared to the available memory. With the default Yocto algorithm to determine the number of parallel build and make threads this can lead to an over commitment of memory/RAM use, and result in very strange issues, with the build hanging (bitbake server process).  What you should do is the following:

    You can then also try our Docker-based build process which we'll be supporting officially starting with SDK v9.2. Would appreciate any feedback you can provide us. See https://github.com/TexasInstruments/ti-docker-images/pkgs/container/ubuntu-distro  This usually helps very much to eliminate any host-machine related setup and dependency issues.

    Regards, Andreas
