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
