Jan Procházka 683da6b46d fatfs: Implementation of disk_status nad disk_initialize for SD/MMC card ... FATFS provides a disk status and disk initialize callback which were not implemented. Implementation has very low impact on SD/MMC speed and fixes issues, when trying to open file when SD card was removed from slot and not deinited. If disk_status returns STA_NOINIT, it will always continue with disk_initialize. If that returns 0, it will continue like everything is working normally. So there has to be the same check as in disk_status. Return of disk_initialize is always checked like this for STA_NOINIT or STA_PROTECT so if command fails, we return the STA_NOINIT. stat = disk_initialize(pdrv); if (stat & STA_NOINIT) return FR_NOT_READY; if (stat & STA_PROTECT) return FR_WRITE_PROTECTED; Closes IDF-4125		2021-11-09 20:17:03 +08:00
