Since version 21.3.0 of mesa3d, the generic broadcom infrastructure (which is called v3d but is used also for VC4) started using NEON instructions. This leads to assembler failures when VC4 is built for 32-bit ARM without NEON: FAILED: src/broadcom/libv3d_neon.a.p/common_v3d_tiling.c.o /home/buildroot/autobuild/instance-2/output-1/host/bin/arm-linux-gcc [...] -c ../src/broadcom/common/v3d_tiling.c /tmp/ccAvufNv.s: Assembler messages: /tmp/ccAvufNv.s:602: Error: selected processor does not support `vldm r7,{q0,q1,q2,q3}' in ARM mode [...] /tmp/ccAvufNv.s:686: Error: selected processor does not support `vstm r7,{q0,q1,q2,q3}' in ARM mode Let the VC4 driver depend on NEON for 32-bit ARM. Aarch64 always has NEON, so no condition is needed there.

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
