Other Parts Discussed in Thread: SYSBIOS

Hi experts,

Is it possible to use AM5728 with non-SMP?　

There is the following sentence in TRM. Can non-SMP also be used?

Best regards,

Sasaki,

In the AM572x the A15 cores are part of a single cluster, with shared L2 cache, MMU, etc, and designed based on SMP architecture as pointed out in the TRM as highlighted. If you are looking to run separate applications on each cores there are mechanisms to do so depending on your requirements.

If looking to run Linux (or HLOS) on one core and RTOS on an other, you can use a hypervisor to carve out resources for the second core to run it's own application. See http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components/Virtualization/Jailhouse.html.

If looking to run RTOS on both cores, there is a good discussion on https://e2e.ti.com/support/processors/f/791/t/678860 along with reference pointers discussing SMP support in SYSBIOS that is a good reference point to review.

Best regards,

Dave
