Hi, guys , I have one Atmel sam4s-xplained-pro board, when I using the nuttx os find some issues. the built-in   MMCSD can't work. following is my testing steps. ```sh ~$ tools/configure.sh sam4s-xplained-pro:nsh ~$ make && openocd -f board/atmel_sam4s_xplained_pro.cfg -c init -c "reset halt" -c "flash write_image erase nuttx.bin 0x00400000" -c "reset" Open On-Chip Debugger 0.10.0+dev-01447-g91c4c83f4-dirty (2020-11-04-12:11) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html Info : auto-selecting first available session transport "swd".

Then I review the .config find content like a s below: ```sh ~$ grep "WDT" .config CONFIG_SAM34_WDT=y CONFIG_WDT_ENABLED_ON_RESET=y # CONFIG_WDT_DISABLE_ON_RESET is not set CONFIG_WDT_TIMEOUT=5000 CONFIG_WDT_MINTIME=2500 CONFIG_WDT_THREAD=y CONFIG_WDT_THREAD_NAME="wdog" CONFIG_WDT_THREAD_INTERVAL=2500 CONFIG_WDT_THREAD_PRIORITY=200 CONFIG_WDT_THREAD_STACKSIZE=512 ``` And, I changed the config and then rebuild it. ```sh grep "WDT" .config CONFIG_SAM34_WDT=y CONFIG_WDT_ENABLED_ON_RESET=y CONFIG_WDT_DISABLE_ON_RESET=y ``` reset problem is disappeared. If reset before had have insert the SD Card, the system likely to stuck or freeze, nsh shell can't allow input anything. ``` BD Registering CDC/ACM serial driver initializing HSMCI sam_waitresponse: ERROR: cmd: 00008101 events: 009b0001 SR: 0410c0e4 mmcsd_sendcmdpoll: ERROR: Wait for response to cmd: 00008101 failed: -116 mmcsd_cardidentify: ERROR: CMD1 RECVR3: -22 sam_waitresponse: ERROR: cmd: 00000208 events: 009b0001 SR: 0410c0e4 mmcsd_sendcmdpoll: ERROR: Wait for response to cmd: 00000208 failed: -116 mmsd_recv_r1: ERROR: R1=00400120 mmcsd_cardidentify: ERROR: mmsd_recv_r1(CMD55) failed: -5 BD Registering CDC/ACM serial driver initializing HSMCI sam_waitresponse: ERROR: cmd: 00008101 events: 009b0001 SR: 0410c0e4 mmcsd_sendcmdpoll: ERROR: Wait for response to cmd: 00008101 failed: -116 mmcsd_cardidentify: ERROR: CMD1 RECVR3: -22 sam_waitresponse: ERROR: cmd: 00000208 events: 009b0001 SR: 0410c0e4 mmcsd_sendcmdpoll: ERROR: Wait for response to cmd: 00000208 failed: -116 mmsd_recv_r1: ERROR: R1=00400120 mmcsd_cardidentify: ERROR: mmsd_recv_r1(CMD55) failed: -5 ``` reset board before not have insert SD Card. ```sh nsh> BD Registering CDC/ACM serial driver initializing HSMCI Mounting procfs to /proc Mounting /dev/mmcsd0 to /fat nx_mount: ERROR: Bind method failed: -19 ERROR: Failed to mount the FAT filesystem: -1 (19) NuttShell (NSH) NuttX-9.1.0 nsh> BD Registering CDC/ACM serial driver initializing HSMCI Mounting procfs to /proc Mounting /dev/mmcsd0 to /fat nx_mount: ERROR: Bind method failed: -19 ERROR: Failed to mount the FAT filesystem: -1 (19) NuttShell (NSH) NuttX-9.1.0 nsh> ``` following is more detail debug output. reset board before not have insert SD Card. when `nsh shell` has ready and then insert a SD card . ```sh BD Registering CDC/ACM serial driver initializing HSMCI sam_hsmci_initialize: Initializing SDIO mmcsd_slotinitialize: minor: 0 mmcsd_hwinitialize: DMA supported: 1 mmcsd_hwinitialize: Attached MMC/SD interrupts mmcsd_slotinitialize: MMC/SD slot is empty sam_cardinserted: Slot 0 inserted: NO Mounting procfs to /proc Mounting /dev/mmcsd0 to /fat find_blockdriver: pathname="/dev/mmcsd0" mmcsd_open: Entry mmcsd_geometry: Entry mmcsd_geometry: IS_EMPTY nx_mount: ERROR: Bind method failed: -19 ERROR: Failed to mount the FAT filesystem: -1 (19) NuttShell (NSH) NuttX-9.1.0 nsh> sam_cardinserted: Slot 0 inserted: YES sam_cardinserted: Slot 0 inserted: YES mmcsd_mediachange: arg: 0x200051c0 mmcsd_probe: type: 0 probed: 0 mmcsd_removed: type: 0 present: 1 sam_waitresponse: ERROR: cmd: 00008101 events: 009b0001 SR: 0410c0e4 mmcsd_sendcmdpoll: ERROR: Wait for response to cmd: 00008101 failed: -116 mmcsd_cardidentify: ERROR: CMD1 RECVR3: -22 mmcsd_cardidentify: SD V2.x card mmcsd_cardidentify: R3: 00ff8000 [.... a lot of repeat here .....] mmcsd_cardidentify: R3: 00ff8000 mmcsd_cardidentify: R3: c0ff8000 mmcsd_cardidentify: SD V2.x card with block addressing mmcsd_decode_cid: mid: 02 oid: 544d pnm: SA08G prv: 7 psn: 1107393314 mdt: c6 crc: 7e mmcsd_sdinitialize: RCA: 1234 mmcsd_decode_csd: CSD: mmcsd_decode_csd: CSD_STRUCTURE: 1 SPEC_VERS: 0 (MMC) mmcsd_decode_csd: TAAC {TIME_UNIT: 6 TIME_VALUE: 1} NSAC: 0 mmcsd_decode_csd: TRAN_SPEED {TRANSFER_RATE_UNIT: 2 TIME_VALUE: 6} mmcsd_decode_csd: CCC: 1461 mmcsd_decode_csd: READ_BL_LEN: 9 READ_BL_PARTIAL: 0 mmcsd_decode_csd: WRITE_BLK_MISALIGN: 0 READ_BLK_MISALIGN: 0 mmcsd_decode_csd: DSR_IMP: 0 mmcsd_decode_csd: SD Block Addressing: mmcsd_decode_csd: C_SIZE: 15199 SD_ER_BLK_EN: 1 mmcsd_decode_csd: SD_SECTOR_SIZE: 127 SD_WP_GRP_SIZE: 0 mmcsd_decode_csd: WP_GRP_EN: 0 MMC DFLT_ECC: 0 (MMC) R2W_FACTOR: 2 mmcsd_decode_csd: WRITE_BL_LEN: 9 WRITE_BL_PARTIAL: 0 mmcsd_decode_csd: FILE_FORMAT_GROUP: 0 COPY: 0 mmcsd_decode_csd: PERM_WRITE_PROTECT: 0 TMP_WRITE_PROTECT: 0 mmcsd_decode_csd: FILE_FORMAT: 0 ECC: 0 (MMC) CRC: 58 mmcsd_decode_csd: Capacity: 7782400Kb, Block size: 512b, nblocks: 15564800 wrprotect: 0 mmsd_decode_scr: SCR: mmsd_decode_scr: SCR_STRUCTURE: 0 SD_VERSION: 2 mmsd_decode_scr: DATA_STATE_AFTER_ERASE: 0 SD_SECURITY: 3 SD_BUS_WIDTHS: 5 mmsd_decode_scr: Manufacturing data: 00000001 mmcsd_widebus: Wide bus operation selected nsh> ls /dev/mmcsd0 mmcsd_geometry: Entry # freeze here , can't response any input unless reset it. ``` now , when I access the device name of `mmcsd0` which will be freeze unless reset.
