Installation on Linux odroid 4.14.180-176 armv7l

1. Install the jdk

$ sudo apt update
$ sudo apt install default-jdk

Edit /etc/environment. Append the following line.

JAVA_HOME=/usr/lib/jvm/default-java

Source the /etc/environment file to apply this environment variable.

$ source /etc/environment

2. Create a new user

$ sudo adduser --system --home /home/ghidra --group --disabled-password --disabled-login ghidra

3. Create a new directory for repositories

$ sudo mkdir /home/ghidra/repositories
$ sudo chown ghidra:ghidra /home/ghidra/repositories

4. Unzip ghidra_version.zip in /home/ghidra

$ cd /home/ghidra
$ sudo unzip /path/to/ghidra_version.zip
$ chown -R ghidra:ghidra ghidra_version

5. Set server config

Edit /home/ghidra/ghidra_version/server/server.conf. Set the following values.

wrapper.app.account=ghidra
ghidra.repositories.dir=/home/ghidra/repositories

6. Remove 64-bit jvm check

Ghidra checks if the jvm version installed is a 64bit version. Since the odroid does not support 64-bit, this check needs to be disabled.
