PROCESSOR-SDK-AM62X: Regarding common use of PSDK

TO

Part Number: PROCESSOR-SDK-AM62X
Other Parts Discussed in Thread: AM62L

Tool/software:

Hi support,

I am currently using AM62, AM64, and AM62L devices.

I would like to build a Yocto system for these devices with one PSDK. 

Can I build a Yocto environment for these devices with *1)PSDK11.00.09.04 ?

*1) PSDK11.00.09.04 is the latest PSDK for AM62 and AM64.

Please let me know if there are any concerns.

Regards,

TO

    Do you mean you want to use one single Yocto source setup (Yocto layers / versions) for all of AM62, AM64, and AM62L?

    For the current SDK v11.0 since the same configuration file for Yocto setup is used (processor-sdk-scarthgap-11.00.09.04-config.txt) for AM62 and AM64 the very same Yocto source tree will allow you building for both platforms. However for AM62L a different configuration file is used (processor-sdk-11.00.05.02-am62lxx-config.txt), which means the source tree setup will be different (actually all layers will point to different commits except meta-arm), and you cannot share this with AM62/AM64, and you should keep this separate. You'd always want to use the exact Yocto configuration referenced in our SDK documentation since this is what we release-tested and what we support.

    Note that you can share the Yocto download and shared state cache folders for better efficiency and space use between different builds setup on the same build machine. You just need to configure those common locations in your conf/local.conf file using the DL_DIR and SSTATE_DIR variables.
