AM62A7-Q1: How to load and run its firmware during MCU R5 SPL startup phase?

Part Number: AM62A7-Q1
Other Parts Discussed in Thread: SK-AM62A-LP

Tool/software:

Hi, TI expert

I would like to inquire about the spL startup related issues of AM62A.The current development environment is as follows.
SDK version: V10.01.00
Board: sk-am62a-lp
Startup method: SPL
Storage: only eMMC

I found in the SDK manual https://software-dl.ti.com/processor-sdk-linux/esd/AM62AX/10_01_00/exports/docs/linux/Foundational_Components/U-Boot/UG-General-Info.html .The SPL of MCU R5, mean R5 u-boot-spl.bin can load and execute the firmware of MCU R5?is it right?

But when I checked the code of MCU R5 SPL, I found that the firmware was not loaded by default.

I would like to ask if this code is missing, right?  I want to load and run the firmware of MCU R5F during the R5 SPL bootting.Do you have any relevant patches or guide?

    Hi Wood,

    The R5 firmware mentioned in the bootflow diagram is the DM firmware, which does the resource management and power management for any other software running on the processor, such as Linux on A53. The R5 SPL doesn't load any applications on other R5 cores.
