About edgex version and architecture

[diablo-1973]

Hi! I'm a newbie starting to learn the use of yurt-edgex-manager these days. I have some questions during the use and your kind help would be highly appreciated. The questions are listed below.

1. I followed the tutorial here (https://github.com/openyurtio/yurt-edgex-manager/blob/main/Documentation/getting_start.md) to deploy EdgeX. Mostly, it relates to the section Create EdgeX. But my pool consists of just one node which is RaspberryPi. In this case, I think only docker image with arm64 could be successfully run on this node. Is yurt-edgex-manager smart enough to get arm version docker image for this or it will get amd version docker image by default?
2. The EdgeX deployment actually is not successful in my environment. Every component of EdgeX can run for a couple of minutes, then it will stop for some reason showing CrashLoopBackOff. It could re-run later, but will fail again. Do you have any experience about this phenomenon? Any comment is helpful since we have no idea about this for now.
3. We have made modification to some component of EdgeX, for instance, edgex-core-command. In practice, for example, we'd like to use version levski but the component edgex-core-command could be from ours. Is this possible for yurt-edgex-manager? I made some study about the configuration, for example, this one https://github.com/openyurtio/yurt-edgex-manager/blob/main/EdgeXConfig/config-nosecty.json. But I'm not sure if it is ok to change the image in the config. so that it will try to fetch image from other places. Any comment for this?
