You have to install these binaries from busybox's menuconfig in order to use them. I think by selecting applets. @Seonghun94

Thanks @kllbrd the busybox menuconfig setting list is...

CONFIG_STATIC=y, listed as "Build BusyBox as a static binary (no shared libs)" in BusyBox Settings → Build Options CONFIG_CROSS_COMPILER_PREFIX=riscv64-unknown-linux-gnu-, listed as "Cross Compiler prefix" in BusyBox Settings → Build Options CONFIG_FEATURE_INSTALLER=y, listed as "Support --install [-s] to install applet links at runtime" in BusyBox Settings → General Configuration CONFIG_INIT=y, listed as "init" in Init utilities CONFIG_ASH=y, listed as "ash" in Shells CONFIG_ASH_JOB_CONTROL=n, listed as "Ash → Job control" in Shells CONFIG_MOUNT=y, listed as "mount" in Linux System Utilities CONFIG_FEATURE_USE_INITTAB=y, listed as "Support reading an inittab file" in Init Utilities

is that right? then, I already done

[ghost]

Yes, this is right. But in order to run binaries via busybox you have to open menuconfig, go to the applets section and select from there which binaries you want. ---Applets Coreutils ---> ls (for example) ...etc. @Seonghun94
