First please find rtconfig_preinc.h
than write the following to the file:

#define RT_USING_LIBC
#define RT_USING_NEWLIBC
#define _POSIX_C_SOURCE 1

Second
There might be some mistakes as follow

RT_SECTION(".irq.uart")

Please send all the'RT_ SECTION'was replaced with'rt_ section'

These methods could solve the problem, but they were not the best way
