Thanks.  That worked well...

Next dumb question is how do you enable CYGSEM_FILEIO_BLOCK_USAGE for the ecos build?
If that isn't enabled, the FS_INFO_BLOCK_USAGE key is not defined, so I can't get any info on CF card free space, etc :-P

#if defined(CYGSEM_FILEIO_BLOCK_USAGE)
    struct cyg_fs_block_usage usage;
    int err = cyg_fs_getinfo(path, FS_INFO_BLOCK_USAGE, &usage, sizeof(usage));
    if ( err >= 0 ) {
        uint64_t blksize, totalblocks, freeblks;
        totalblocks = usage.total_blocks;
        freeblks = usage.free_blocks;
        blksize = usage.block_size;
        diskSize = totalblocks*blksize;
        freeSpace = freeblks*blksize;
        usedSpace = diskSize - freeSpace;
        return true;
    }
#endif
