Drivers (Zephyr RTOS)
Note: If you are using a Windows or MacOS, there are also drivers available on the Download page. Simply click on the executable or package to install the drivers on the respective operating system.
We'll need some J-Link software so we can communicate with the Segger J-Link OB on the RED-V. Head to Segger to download the software under "J-Link Software and Documentation pack for Linux, DEB installer, 64-bit." Read through the license agreement before accepting the terms and hit the "Download software" button. We used version 6.56a on Ubuntu v18.04.3 when writing this tutorial.
We should still be in the Downloads folder, so installing the software is as simple as running the below command. Depending on the software package, you may need to update the version name.
language:bash
sudo apt install ./JLink_Linux_V646a_x86_64.deb
