The kernel 5.5.7 curently used by the test doesn't build with host gcc >= 10 due the gcc default -fno-common. See GCC 10 porting guide [1]. /usr/bin/ld: scripts/dtc/dtc-parser.tab.o:(.bss+0x20): multiple definition of `yylloc'; scripts/dtc/dtc-lexer.lex.o:(.bss+0x0): first defined here But we can't just update this test to the next linux kernel LTS 5.10.y since the minimum gcc version has been updated to gcc 4.9 since 5.8 kernel [2] and the Sourcery CodeBench ARM 2014.05 is used (gcc 4.8 based). Enable arm cortex A9 and VFP support to switch to the ARM arm prebuilt toolchain (the Bootlin toolchain could be used). While at it use the prebuilt buildin kernel for the vexpress target recently updated to 5.10.7.

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.
