We can debate that once we get there. We support uclibc-ng and glibc. 1. For uclibc-ng, linux-4.20 could run with it. 2. For glibc, Maybe we could support 32-bit + 64-bit time_t with KERNEL_VERSION, or just only 64-bit then linux-4.20 couldn't work with the csky first glibc release. Best Regards Guo Ren
