Hi
I am woking on J721E EVM Jailhouse Hypervisor, i am getting kernel panic while creating cell, running below the script file /usr/share/ti/util-scripts/demo/cockpit-demo-cluster-VM.sh
the script consists below commands
#!/bin/bash
#Utility to run integrated cockpit on DRA8xx devices
#This script needs to be run on the root cell (cluster VM)
monitor_ivi_vm() {
sleep 100
ti-heartbeat-are-you-there
}
