[HELP] How to get the more cpu status when NuttX is running

[lzc1001]

Description

Hi everyone,
I have boot NuttX on FVP multi-core, and those cores are armv8a arch, but I don't know how to get the status of each core.
I found "coredump" command in NuttX documentation, but I don't know how to use it on FVP. It seem that this command isn't support FVP
Thank you every much!

which state do you want to get?

[lzc1001]

@xiaoxiang781216 I want to get each core ID by /proc/cpuinfo on FVP A510, But the related code isn't implemented for ARMV8A. I want get these information to verify multi-core are both active. I am also trying to write a simple multi-task code for verifing this.

@xiaoxiang781216 hhh, I have run apps/testing/smp_main.c to verify each core is activity. Thank you very much, I wonder if there's another way to check or prove this?😄

ps could also show multiple idle thread, and testing/cpuload could simulate the loading on the specific cpu core.
