I have a board(nanopi r4s with rk3399 and 4g ram) and I want to run a minecraft server on it. (with adoptopenjdk arm64)

After flashing  the SD image I have the following problems:

• I can't find the IP address of my board through the IP finding tool. (unable to ssh to my system)

• # This happened on many OSes, including Debian OS in my VM
  
  $ ls ./
  . .. java (many other files)
  $ ./java
  bash: ./java: No such file or directory

  Something must went wrong...

• How to plug the network cable? There are 2 ETH ports on the board. The first one has a "WAN" on it. Another one has a "LAN" on it. (scroll down)

 

 

 

                                                   |=                                                          | WAN

internet ---------WAN- router -|= LAN ======= ?? ========                          Nanopi r4s   

                                                   |=                                                          | LAN

Check your router interface. Armbian sets ethernet interface/s by default to DHCP.

./java

Install openjdk

Does not matter. Both are GBe PHY. One is directly from the SoC. The other is connected internally via PCIe.

Install openjdk

 

# my console output, using Adoptium JDK package

-bash: ./java: No such file or directory

When I'm running "ls " command the java shows up;

But when I execute it, the file can't be executed.

Never heard of Adoptium JDK. Make sure you have arm64 binary. x86 or amd64 will not work.

 

Install openjdk17-jre from apt and it will work.
