I’d wanted to build a headless PlexAmp setup on my old Pi for a long time but didn’t have access to it (long story). I recently got my hands back on it and was bummed to see the zeroth step is “have a 64-bit capable Raspberry Pi”. I’m glad I double-checked the forum to find this thread that says it does work on 32-bit models too. Well, there have been a lot of Pis since I got my Model B Rev 2, and ARMv6 doesn’t seem to be supported by much anymore. I was able to (slowly) build Node v12.22.12 from source but I only get “Illegal instruction” when I try to run PlexAmp. Is it possible for me to get an ARMv6 compatible version, or is there a step I can take to make it compatible?
Here are the steps I took. Also documenting it as a reference for others.
# I'm using the Raspberry Pi Model B Rev 2
# I used the Raspberry Pi Imager to set up Raspberry Pi OS Lite (32-bit)
# I increased the virtual memory from 100MB to 1GB. Not sure if it's necessary, but I only have 512MB RAM, it doesn't hurt, and I have plenty of space on this 8GB card.
