I want to do some automated unit testing of my firmware modules. I'm using Sput Unit Testing Framework and want to save the results in a text file via Semihosting. For this purpose I need fopen() and fprintf() to open a file and write text to it. At the moment I'm able to output my reults to the console via printf (I changed all fprintf() to printf() in Sput Framework). But I was not able to get working fopen() and fprintf(). In the EWL C reference manual is a chapter about the configuration of the library. I set "_EWL_OS_DISK_FILE_SUPPORT" macro to "1" in the "ansi_prefix.ARM.h" header file to enable supoort of the functions, but it didn't work.
How can I enable the file support?
