Dear Leo,
Thanks for this replaying.
After keying two commands, I got these information.
Thanks.!!! BRs, Eric

Dears,
I am trying to get the data, but still failed. (orz..) If you have any suggestion or possible solutions, please tell me.
Based on your yersterday shared log, seems ETM has not been initialized properly. So suggest to firstly check if CoreSight devices have been initialized or not.
Could you check below folder?
# ls /sys/bus/coresight/devices/ etm0 etm2 etm4 funnel0 funnel2 funnel4 stm0 tmc_etf1 tpiu0 etm1 etm3 etm5 funnel1 funnel3 replicator0 tmc_etf0 tmc_etr0
And please confirm if ETM/ETR/ETF has been initialized or not, a simple way is to use below command:
# dmesg | grep -i coresight [ 5.390787] coresight-tmc 20070000.etr: Adding to iommu group 1 [ 5.400714] coresight etm2: CPU2: ETM v4.0 initialized [ 5.407232] coresight etm3: CPU3: ETM v4.0 initialized [ 5.412955] coresight etm4: CPU4: ETM v4.0 initialized [ 5.418689] coresight etm5: CPU5: ETM v4.0 initialized [ 5.425828] coresight etm1: CPU1: ETM v4.0 initialized [ 5.431517] coresight stm0: STM500 initialized [ 5.436390] coresight etm0: CPU0: ETM v4.0 initialized

Dear AI,
Big Thank for your replaying.
