I have an older Raspberry Pi 2 that I'd like to put the latest compatible OS on. The specs of my Raspberry Pi: Raspberry Pi 2 Model B 1 GB from Canakit.com It came with a 8 GB SD card. I bought it about June, 2015.
My understanding is that I can download the latest compatible OS version onto an SD card on my Windows 10 machine. I'm getting this idea from: https://www.raspberrypi.org/documentation/installation/installing-images/
However, from the mentioned document, I have no idea which OS version I should be looking for. Surely some run on Raspberry Pi 4 an not 2? Also, other documents have mentioned that the firmware might need updating. How is this done?
P.S. I know I'm not suppose to mentioned more than one issue/question, but I can't resist saying that I'm doing all this to (1) learn more about Raspberry/Linux and (2) I'm taking an algorithms course through Coursera.org. I'm hoping I can put a JAVA development environment (Eclipse?) on my Pi 2 and not put it on my work computer.
