The VideoCore blobs for the Raspberry Pi 1, 2, 3, Zero, Zero W and Zero 2 W are differents from the ones for the Raspberry Pi 4 and the Compute Module 4. The VideoCore blobs for the Raspberry Pi 4 are named with a 4[1] (i.e. start4.elf, start4x.elf, start4db.elf and start4cd.elf). This precises which VideoCore firmware blob files are present on the Raspberry Pi 1, 2, 3, Zero W, Zero 2 W and which files are present on the the Rapsberry Pi 4 and the Compute Module 4. Note: The VideoCore blobs for the Raspberry Pi 5 are self-contained in its bootloader EEPROM[1][2]; there is no additional files for pi5.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
