![]() So what are those files? Below is applicable for the Pi Zero…other models have differing requirements (which leads to the complexity). ![]() What Is A Raspberry Pi Bootable Image?Īt its most basic, it is a boot partition with a FAT32 filesystem containing a few binary and text configuration files. Having all the necessary pieces self-contained within the plugin reduces friction. That way, one could code embedded apps without having to re-burn a new image to the CD card each time. I wanted deployment to occur without having to alter the bootable image each time, and I wanted the plugin to be able to construct a bootable image for the Pi with a simple serial bootloader to facilitate. The reason for my project is to bundle up all the necessary assembler, Java VM, class loader, and boot minutiae in one place, so that all one had to do is write Java code, build, and deploy. It has always seemed to me that there is a bit of “voodoo” involved in getting this right. One of my requirements, and one of my gripes with the Pi, is the opaque “image” that has to be written to the SD card to boot the Pi. ![]() ![]() I was in the process of building a Gradle plugin for my bare-metal embedded Java on Raspberry Pi project.
