AM62A7-Q1: Get the falcon mode file using Yocto project

Hi Yuwei,

YuWei Wu said:

We hope to integrate the files required by falcon mode into the YOCTO project recently.

Falcon mode requires multiple files, which are compiled by MCU+SDK.

Can TI provide a Yocto build target to complete the falcon mode file build process?

We don't have this all integrated at the moment; as you stated some artifacts (initial SBL bootloader) part of our official Falcon boot solution (https://software-dl.ti.com/mcu-plus-sdk/esd/AM62AX/09_02_00_38/exports/docs/api_guide_am62ax/TOOLS_BOOT.html#LINUX_APPIMAGE_GEN_TOOL) are based on the MCU+ SDK which is a completely different/independent build environment.

Still of course your ask for some level of integration is a valid request. What I would do for now is to create an overall build environment, performing both Yocto and MCU+ SDK based builds and wrapping them using a top-level Makefile-based approach, which is then combining the output artifacts into your final image for example. All this of course will be heavily dependent what you are trying to build, what boot mode support you need (final output image file format), etc. If you do decide on following this scheme and need help with specific integration aspects let me know.

HI Andreas

We currently want to use falcon mode to reduce startup time, and this is done with the MCU+SDK package.

But we had trouble trying to save the work to Yocto, TI didn't provide a reference for the Falcon mode.

Can TI provide a Yocto reference project for FALCON mode?

Thanks,

Yuwei

Hi Yuwei,

as per my earlier comment we don't have this at the moment in an integrated fashion. However the AM62A Linux/Yocto SDK User's Guide actually has a section on boot time optimization as well and how MCU+ SDK-based SBL bootloader is integrated and used in this context:
