commit edbc03e40a3acea0be2dfa992c42a5a251fce412 Author: Alan Carvalho de Assis <[email protected]> AuthorDate: Tue Jul 28 05:11:51 2026 -0300 boards: stm32f4discovery: add toybox defconfig Same shape as boards/sim/sim/sim/configs/toybox: CONFIG_SYSTEM_TOYBOX=y with CONFIG_INIT_ENTRYPOINT="toybox_main", built on top of the existing stm32f4discovery:nsh defconfig's board/console setup. Needs several options nsh's defconfig doesn't, since Toybox's library code references more of NuttX's libc unconditionally than NSH does: CONFIG_ALLOW_MIT_COMPONENTS (gates CONFIG_LIBC_REGEX -- grep/sed/etc), CONFIG_ARCH_SETJMP_H (sigjmp_buf; the REPL's rebound trap uses sigsetjmp/siglongjmp), CONFIG_LIBC_EXECFUNCS, CONFIG_LIBC_LOCALE, CONFIG_LIBC_LOCALTIME, CONFIG_PIPES, CONFIG_PSEUDOFS_SOFTLINKS, CONFIG_FS_NOTIFY (tail -f), CONFIG_SCHED_HAVE_PARENT (waitpid()).
