Library not fully initialized when card is inserted

[markregel]

The global variables need to be initialized whenever a new SD card is initialized. To accomplish this task I added the function below and call it whenever a card needs to be initialized. Without doing this a bad card can leave the library in a non-functional state even after a new card is inserted.

//*******************************************************
//*******************************************************
//********** RESET NEW MMC / SD CARD ****************
//*******************************************************
//*******************************************************
//call this function to reset the library
BYTE ffs_reset(void)
{
BYTE b_temp;

ffs_card_ok = 0; //Flag that card not OK

sm_ffs_process = FFS_PROCESS_NO_CARD;
file_system_information_sector = 0;
ffs_no_of_heads = 0;
ffs_no_of_sectors_per_track = 0;
ffs_no_of_partition_sectors = 0;
card_is_high_capacity = 0;
chk_cmd_response_data = 0;

number_of_root_directory_sectors = 0; //Only used by FAT16, 0 for FAT32
ffs_buffer_needs_writing_to_card = 0;
ffs_buffer_contains_lba = 0xffffffff;
fat1_start_sector = 0;
root_directory_start_sector_cluster = 0; //Start sector for FAT16, start clustor for FAT32
data_area_start_sector = 0;
disk_is_fat_32 = 0;
sectors_per_cluster = 0;
last_found_free_cluster = 0;
sectors_per_fat = 0;
active_fat_table_flags = 0;
read_write_directory_last_lba = 0;
read_write_directory_last_entry = 0;
ffs_card_write_protected = 0;

//Reset all file handlers
for (b_temp = 0; b_temp < FFS_FOPEN_MAX; b_temp++)
ffs_file[b_temp].flags.bits.file_is_open = 0;

return 1;
}
