rpi-open-firmware: open-source VPU side bootloader for Raspberry Pi
&gt;It&#x27;s not being developed but it&#x27;s not dead.<p>The bigger problem is that the pi is a solution waiting for a problem, and until it sees more purchase outside everyones desk drawer there is very little impetus to clean up the ARM&#x2F;Microsoft dumpster fire that virtualizes a guest OS on the device.  The only people pedaling it are FAANG, war-drumming furiously for kids to learn to code for the love of god so they can stop paying programmers a reasonable wage.<p>everything the pi is touted to do, you can either accomplish with existing general computing or something like an arduino (and as a benefit, learn some electrical theory as well.)
