Hi Alan,
fopen will not work, it is a posix call which is not fully implemented in the c library (newlib).
Newlib requires an external implementation of system call open (a stub), which it is not provided since we do not know on which media you want to open a file.
I would recommend you to use the FatFS on the SDMMC (sdcard).
