AWS Greengrass does not start on TX2

Hi Ac4289,

Where did you install Greengrass? What are the contents of /greengrass/certs?

Are there any messages in /greengrass/ggc/var/log/crash.log?

Thanks,
Keagen

Hi Keagen,

Thank you for checking!
I install Greengrass under /home/nvidia/greengrass.
Here are the contents in certs folder:

$ ls
6c6e554fbc.cert.pem     6c6e554fbc.public.key  root.ca.pem  6c6e554fbc.private.key  README

And here is the crash.log:

Error occured while generating TLS config: open /greengrass/certs/root.ca.pem: no such file or directory
The Greengrass daemon process with [pid = 6333] died

Hi Ac4289,

You'll need to modify your config.json file to list the correct paths for all your certs. It looks like your certs are in /home/nvidia/greengrass/certs

Thanks,

Yes, this works! Thank you very much!

I had the same issue & I solved it using

"ggHost" : "greengrass-ats.iot.us-east-1.amazonaws.com",

},
"runtime" : {
"cgroup" : {
"useSystemd" : "yes"
}
},
"managedRespawn" : false,
