Hi TI teams:
I downloaded the SDK file "ti-processor-sdk-linux-am62xx-evm-10.01.10.04-Linux-x86-Install. bin" from the TI website, and after installation, I obtained the "k3r5-devkit" as shown in the following figure
I want to generate "k3r5-devkit" myself through Yocto. How do I do it? conud you please provide detailed steps.

If you build the `meta-toolchain-arago-tisdk` target as per https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/11_00_09_04/exports/docs/linux/Overview_Building_the_SDK.html#build-options both the regular and the k3r5 devkit will get generated.

I executed 'bitbake meta toolchain argo tisdk' and the result is shown in the following figure：

and executed 'arago-2023.10-aarch64-linux-tisdk.sh', the results are shown in the following figure:

Hi Kevin,

ah ok I see now where the issue is. Having a quick look at the source tree the `k3r5-devkit` seems to only get generated when building the entire TI SDK installer bundle (image target for this is `tisdk-core-bundle`) which however is a very large/massive build as it builds everything. You can try this but it will likely take a long time.

I'm checking with the team if there's a better/quicker way to build this.

Apparently the proper build target to build that devkit/toolchain is `mc:k3r5:meta-toolchain-arago`, can you please try this:

$ MACHINE=am62xx-evm bitbake -k mc:k3r5:meta-toolchain-arago

It is actually documented in the AM68x SDK documentation at https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-am68/10_01_08_01/exports/docs/linux/Overview_Building_the_SDK.html#build-options but missing in the AM62x documentation. I'll file an internal ticket to have this updated.

Regards, Andreas
