Open Source Summit India 2025

This session will be about my current and ongoing experience at Texas Instruments where I have been working on enabling Zephyr for AM243x platform, a multiprocessor heterogeneous evaluation module with both Cortex-R and Cortex-M cores and all the challenges I have faced in the process. This includes adding board support, device trees, device drivers, as well as testing the peripherals to ensure proper function on Zephyr. I will also be walking through the process of writing a device driver and the device driver model for Zephyr, and my experience and the challenges I encountered in doing so. The talk will also include the gaps and challenges involved in booting a heterogeneous SoC, the limitations I faced with MCUBoot as a bootloader for Zephyr, the potential alternatives, and the solution involving TI's RTOS bootloader. The aforementioned topics may serve as a reference guide for enabling more heterogeneous SoCs in the future.
