Developer Mode installs other debug/development tools such as tcpdump?

HI.
I didn’t understand DeveloperMode on the website. How do I install tcpdump? I don’t quite understand what it means?

https://docs.legato.io/latest/basicTargetDevMode.html

find / -name tcpdump
/legato/apps/9c276d65dca7b6c46a72f5f9a0a8cbaa/read-only/sbin/tcpdump
/legato/systems/current/appsWriteable/devMode/sbin/tcpdump
/mnt/flash/legato/apps/9c276d65dca7b6c46a72f5f9a0a8cbaa/read-only/sbin/tcpdump
/mnt/flash/legato/systems/current/appsWriteable/devMode/sbin/tcpdump

Didn’t tcpdump already appear there?

Need to add a long path in front of it, is there any other way?

You can create a link to it or you can copy the binary to tmp folder

This is a method, thank you

Can anyone provide a step by step solution on how this is done?
