I have a problem with RTL_ARM using flash file system. I can not use functions in stdio.h. When I use whatever function in stdio.h, program jum to an enless loop in Retarget.c immediately. After that, i installed RLARM library and use some functions as fs_fopen, fs_fwrite,... but they has many errors. I can not repair it. Please help me!! Thanks very much
Retarget means that there are stub functions that you should implement. For example, exactly what is stdout in an embedded system?
