You might want to look into the file image created, and even untar it with your host to see what it produces.
Here are the commands I use from an old repo (with CVS and SVN vc), after placing the files in a directory called "files" cd files tar -cvf ../FileSystemImage --exclude CVS --exclude .cvsignore --exclude .svn . cd .. rtems-bin2c FileSystemImage FileSystemImage This creates the .c and .h files I need so that I can use in my init(): Untar_FromMemory(FileSystemImage, FileSystemImage_size) I also used #define CONFIGURE_USE_IMFS_AS_BASE_FILESYSTEM #define CONFIGURE_LIBIO_MAXIMUM_FILE_DESCRIPTORS 40 #define CONFIGURE_IMFS_MEMFILE_BYTES_PER_BLOCK 512 All of this was awhile ago, but maybe these pointers will help you. -Gedare >> where TARFILE_START is the macro with the name of the array , TARFILE_SIZE >> is the size of the array. >> >> But when I run the program, I get errors of the form >> >> "Untar: failed to create file <folder>/<filename>" >> >> for all the files in the tar archive (there are about 10 files, 10 errors). >> >> There are no build errors, and since my application recognizes files >> present in the tar archive, I think possibly I am missing to initialize >> something. >> >> Help would be really appreciated. >> >> Thanks and Regards, >> Sujay Raj >> _______________________________________________ >> devel mailing list >> devel@rtems.org >> http://lists.rtems.org/mailman/listinfo/devel > > > _______________________________________________ > devel mailing list > devel@rtems.org > http://lists.rtems.org/mailman/listinfo/devel _______________________________________________ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
