Hello,
The SDK for the RUTXnn devices contains precompiled files for a specific gcc/glibc version, depending on the Linux distribution version one uses they can generate link/execution errors.
The five files are in scripts/config: conf mconf conf.o mconf.o zconf.tab.o.
For example, "./scripts/config/conf: /usr/lib64/libc.so.6: version `GLIBC_2.27' not found (required by ./scripts/config/conf)
A missing make clean maybe when building the SDK ?
Regards,
