SK-AM62-LP: Sysconfig for A53 on AM62x MCU SDK

Part Number: SK-AM62-LP
Other Parts Discussed in Thread: SYSCONFIG

Hello,

I am developing a FreeRTOS application for the A53 core on AM62x. I have noticed that support for this scenario is available in the AM64x MCU SDK. However, when I use SysConfig from the AM62x, I am unable to select the A53 core (for example for this driver porting layer). Is there a way to enable this core for the MCU SDK on the AM62x?

BR

    Hello,

    Thank you for reaching out to Texas Instruments E2E support forum.

     A53 FreeRTOS/NoRTOS development on AM64x SOC are experimental and is not supported by TI.

    Currently there are no A53 FreeRTOS/NoRTOS examples for AM62x MCU+SDK.

    You can expect A53 examples for FreeRTOS/NoRTOS in the upcoming release of MCU+SDK.

    Hello,

    Thank you for your replay. Until now I managed to copy armv8 specific files from AM64x and I got a booting image. However, after invoking the first delay, the cpu is stuck in an idle task.

    The board is flashed with null sbl and I loaded the binary via CCS on core 0. I noticed that I am not getting any tick interrupts.

    For a system tick I am using TIMER6 and it seems to work (counter is incrementing...). As far as I know it is IRQ 158.

    When I stoped the target I was able to check GICD module:

    • CTLR = 0x12
    • ISENABLER4 = 0x40000000
    • ICENABLER4 = 0x40000000
    • ISPENDR4 = 0x40000000
    • ICPENDR4 = 0x40000000
    • IPRIORITYR39 = 0x20902020

    Is there any obvious difference between AM64x and AM62x in terms of interrupts? What should I check next?

    You can check the interrupt connection details in the AM62x TRM. Please refer "section 10.1.7/8/9/10/11 Interrupt connection" for more details.

    As A53 RTOS/NoRTOS is an experimental feature on AM62x/AM243x devices and is not supported by TI. We will not be able to support queries related to A53 RTOS/NoRTOS implementation.
