uClibc currently supports RISC-V with a soft-float or 64-bit
hard-float ABI, but not 32-bit hard-float. Selecting
BR2_RISCV_ABI_LP64F results in a build failure:
./include/sys/asm.h:42:4: error: #error unsupported FLEN
42 | # error unsupported FLEN
| ^~~~~
Change the conditions for BR2_PACKAGE_UCLIBC_ARCH_SUPPORTS
accordingly.

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.
