Tool/software:

Hi,
do we have any boot time benchmarks for a bare metal or freeRTOS example on A53?

Regards, Holger

    Hello Holger,

    Could you please confirm who the customer is?
    Is the customer planning to use FreeRTOS on the A53 core?

    At present, we do not have a benchmark for FreeRTOS boot time.

    However, the AM62L boot flow is different from AM62x/A/P/D and AM64x/AM243 family devices.

    The AM62L supports a two-stage bootloader:
    • First stage: Initializes DDR
    • Second stage: Directly loads the application

    As a result, AM62L is expected to have lower boot time compared to other AM62x/A/P/D and AM64x/AM243 SoCs.

    Notably, AM62L does not require an SBL because the ROM itself loads the application in the second stage.
    We typically require an SBL when using A53 cores in AMP mode, but AMP mode has cache limitations that may degrade performance.

    For real-time use cases, the recommendation is to use SMP mode on A53, in which case no SBL is needed.

    Please clarify why the customer is requesting boot-time details. If boot timing is a key requirement, we can work closely to get these details or measure internally .

    Regards,

    Anil.
