: This file runs on the "Wakeup Domain" (typically an ARM Cortex-R5 core). Because this core is 32-bit, the tiboot3.bin file must be compiled using a 32-bit cross-compiler , even if your main processor is 64-bit.
The file is the primary bootloader image for Texas Instruments (TI) processors based on the K3 Multicore SoC architecture , such as the AM6x and Jacinto 7 (J7) families. It is the first piece of software loaded by the internal ROM code from the boot media (like an SD card or eMMC) and runs on a dedicated 32-bit Cortex-R5F microcontroller core within the SoC's wakeup domain.
