Takeyoshi, I did some work on the SDMCC driver today, it compiles now and I pushed the code to the branch. I will try it and let you know how it goes. I am still not sure everything is right, for instance why do I have to specify SDMMC0_SIZE? The sama5d2x_memorymap.c file seems to need it. But it should not be operating in memory-mapped mode, so I'm confused.
Here are the config settings I used: # # This file is autogenerated: PLEASE DO NOT EDIT IT. # # You can use "make menuconfig" to make any modifications to the installed .config file. # You can then do "make savedefconfig" to generate a new defconfig file that includes your # modifications. # # CONFIG_AUDIO_FORMAT_MP3 is not set # CONFIG_DISABLE_OS_API is not set # CONFIG_NSH_ARGCAT is not set # CONFIG_NSH_CMDOPT_HEXDUMP is not set # CONFIG_NSH_CMDPARMS is not set # CONFIG_SAMA5_UART0 is not set CONFIG_ARCH="arm" CONFIG_ARCH_BOARD="sama5d2-xult" CONFIG_ARCH_BOARD_SAMA5D2_XULT=y CONFIG_ARCH_BUTTONS=y CONFIG_ARCH_CHIP="sama5" CONFIG_ARCH_CHIP_ATSAMA5D27=y CONFIG_ARCH_CHIP_SAMA5=y CONFIG_ARCH_CHIP_SAMA5D2=y CONFIG_ARCH_INTERRUPTSTACK=2048 CONFIG_ARCH_IRQBUTTONS=y CONFIG_ARCH_LOWVECTORS=y CONFIG_ARCH_STACKDUMP=y CONFIG_AUDIO=y CONFIG_AUDIO_NUM_BUFFERS=8 CONFIG_BOARD_LOOPSPERMSEC=65775 CONFIG_BOOT_RUNFROMSDRAM=y CONFIG_BUILTIN=y CONFIG_DEBUG_FEATURES=y CONFIG_DEBUG_FULLOPT=y CONFIG_DEBUG_SYMBOLS=y CONFIG_DEV_LOOP=y CONFIG_DEV_ZERO=y CONFIG_EXAMPLES_HELLO=y CONFIG_EXAMPLES_PARTITION=y CONFIG_EXAMPLES_TCPBLASTER=y CONFIG_EXAMPLES_TCPECHO=y CONFIG_EXAMPLES_WGET=y CONFIG_EXAMPLES_WGET_URL="http://10.0.0.1/"; CONFIG_FAT_LCNAMES=y CONFIG_FAT_LFN=y CONFIG_FS_FAT=y CONFIG_FS_PROCFS=y CONFIG_FS_PROCFS_EXCLUDE_VERSION=y CONFIG_FS_ROMFS=y CONFIG_HAVE_CXX=y CONFIG_HAVE_CXXINITIALIZE=y CONFIG_HIDKBD_POLLUSEC=80000 CONFIG_I2S=y CONFIG_INTELHEX_BINARY=y CONFIG_IOB_NBUFFERS=72 CONFIG_IOB_THROTTLE=16 CONFIG_MAX_TASKS=16 CONFIG_MAX_WDOGPARMS=2 CONFIG_NETINIT_NETLOCAL=y CONFIG_NETINIT_NOMAC=y CONFIG_NETUTILS_NETLIB_GENERICURLPARSER=y CONFIG_NETUTILS_TELNETC=y CONFIG_NETUTILS_WEBCLIENT=y CONFIG_NET_ARP_IPIN=y CONFIG_NET_ARP_SEND=y CONFIG_NET_BROADCAST=y CONFIG_NET_CDCECM=y CONFIG_NET_ETH_PKTSIZE=1514 CONFIG_NET_ICMP=y CONFIG_NET_ICMP_SOCKET=y CONFIG_NET_ROUTE=y CONFIG_NET_STATISTICS=y CONFIG_NET_TCP=y CONFIG_NET_TCPBACKLOG=y CONFIG_NET_TCP_NOTIFIER=y CONFIG_NET_TCP_WRITE_BUFFERS=y CONFIG_NET_UDP=y CONFIG_NFILE_DESCRIPTORS=8 CONFIG_NFILE_STREAMS=8 CONFIG_NSH_ARCHINIT=y CONFIG_NSH_BUILTIN_APPS=y CONFIG_NSH_FILEIOSIZE=512 CONFIG_NSH_PROMPT_STRING="nsh> " CONFIG_NSH_QUOTE=y CONFIG_NSH_READLINE=y CONFIG_NSH_ROMFSETC=y CONFIG_NXPLAYER_DEFAULT_MEDIADIR="/mnt/sdcard" CONFIG_NXPLAYER_INCLUDE_SYSTEM_RESET=y CONFIG_NXPLAYER_RECURSIVE_MEDIA_SEARCH=y CONFIG_PREALLOC_MQ_MSGS=4 CONFIG_PREALLOC_TIMERS=4 CONFIG_PREALLOC_WDOGS=16 CONFIG_RAMLOG=y CONFIG_RAMLOG_BUFSIZE=16384 CONFIG_RAMLOG_SYSLOG=y CONFIG_RAM_SIZE=268435456 CONFIG_RAM_START=0x20000000 CONFIG_RAM_VSTART=0x20000000 CONFIG_RAW_BINARY=y CONFIG_READLINE_CMD_HISTORY=y CONFIG_READLINE_CMD_HISTORY_LEN=100 CONFIG_READLINE_CMD_HISTORY_LINELEN=120 CONFIG_READLINE_TABCOMPLETION=y CONFIG_RR_INTERVAL=200 CONFIG_SAMA5D2XULT_528MHZ=y CONFIG_SAMA5D2XULT_USBHOST_STACKSIZE=2048 CONFIG_SAMA5_BOOT_SDRAM=y CONFIG_SAMA5_DDRCS_HEAP_END=0x2fa00000 CONFIG_SAMA5_DDRCS_RESERVE=y CONFIG_SAMA5_EHCI=y CONFIG_SAMA5_HSMC=y CONFIG_SAMA5_OHCI=y CONFIG_SAMA5_PIOA_IRQ=y CONFIG_SAMA5_PIOB_IRQ=y CONFIG_SAMA5_PIOC_IRQ=y CONFIG_SAMA5_PIO_IRQ=y CONFIG_SAMA5_RTC=y CONFIG_SAMA5_SDMMC0=y CONFIG_SAMA5_TRNG=y CONFIG_SAMA5_UART1=y CONFIG_SAMA5_UDPHS=y CONFIG_SAMA5_UHPHS=y CONFIG_SCHED_HPWORKPRIORITY=192 CONFIG_SCHED_LPNTHREADS=2 CONFIG_SCHED_LPWORK=y CONFIG_SCHED_WAITPID=y CONFIG_SDCLONE_DISABLE=y CONFIG_SERIAL_TERMIOS=y CONFIG_SIG_DEFAULT=y CONFIG_SIG_EVTHREAD=y CONFIG_START_DAY=31 CONFIG_START_MONTH=7 CONFIG_START_YEAR=2014 CONFIG_SYMTAB_ORDEREDBYNAME=y CONFIG_SYSLOG_TIMESTAMP=y CONFIG_SYSTEM_NSH=y CONFIG_SYSTEM_NSH_CXXINITIALIZE=y CONFIG_SYSTEM_NXPLAYER=y CONFIG_SYSTEM_PING=y CONFIG_SYSTEM_VI=y CONFIG_TTY_SIGINT=y CONFIG_TTY_SIGSTP=y CONFIG_UART1_SERIAL_CONSOLE=y CONFIG_USBDEV=y CONFIG_USBDEV_DMA=y CONFIG_USBDEV_DUALSPEED=y CONFIG_USBDEV_TRACE=y CONFIG_USBDEV_TRACE_NRECORDS=512 CONFIG_USBHOST_HIDKBD=y CONFIG_USBHOST_MSC=y CONFIG_USER_ENTRYPOINT="nsh_main" CONFIG_WDOG_INTRESERVE=2 -adam On Mon, Mar 16, 2020 at 7:33 PM Adam Feuer <a...@starcat.io> wrote: > Takeyoshi, > > I pushed some more files to the SDMMC branch— changing the IMXRT_HSDC to > SAMA5_SDMMC throughout.
