I tried fixing it but I gave up hacking on buildroot and went ahead and made a tiny busybox+dropbear linux root image builder. Caveat: it requires sudo as it loop mounts an ext4 filesystem - https://github.com/michaeljclark/busybear-linux There is obviously some buildroot patches I must be missing or I'm on the wrong branch. When I run it a third time, the build log is shorter, but I get the same error. $ make qemu make -C /home/mclark/src/sifive/freedom-u-sdk/buildroot RISCV=/opt/riscv/toolchain PATH=/opt/riscv/toolchain/bin:/home/mclark/bin:/home/mclark/.local/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/opt/riscv/toolchain/bin:/opt/riscv/qemu/bin:/opt/riscv/musl-riscv-toolchain-7.2.0-7/bin O=/home/mclark/src/sifive/freedom-u-sdk/work/buildroot_initramfs make[1]: Entering directory '/home/mclark/src/sifive/freedom-u-sdk/buildroot' >>> toolchain-external undefined Configuring Incorrect selection of kernel headers: expected 4.6.x, got 4.13.x package/pkg-generic.mk:185: recipe for target '/home/mclark/src/sifive/freedom-u-sdk/work/buildroot_initramfs/build/toolchain-external-undefined/.stamp_configured' failed make[1]: *** [/home/mclark/src/sifive/freedom-u-sdk/work/buildroot_initramfs/build/toolchain-external-undefined/.stamp_configured] Error 1 make[1]: Leaving directory '/home/mclark/src/sifive/freedom-u-sdk/buildroot' Makefile:87: recipe for target '/home/mclark/src/sifive/freedom-u-sdk/work/buildroot_initramfs/images/rootfs.tar' failed make: *** [/home/mclark/src/sifive/freedom-u-sdk/work/buildroot_initramfs/images/rootfs.tar] Error 2 It's possibly my linux toolchain version.
