Upon reception of a valid read command the card will respond with a response token followed by a data token (refer to Figure 7-3). In case of Standard Capacity Card, the One great thing about MMC is the Boot Operation Mode. This is a very simple protocol that allows the host to easily address and clock in the specially configured boot partition off the card. As far as I can tell this is only available on eMMC parts though which normally come in BGAs. 读一块使用的命令是cmd17,第多块使用的命令是cmd18。 trnmod寄存器,设置传输模式。 第五位:mul1sin0 ,多块操作使能。对于读一块,设置为0。对于读多块,要设置为1。每读取一块数据,blkcnt寄存器会减一,当减到0的时候,读取结束。 読込み手順(MMC.asm) 1) チップ選択オン 2) CMD17出力 (コマンド、アドレス、CRC。 全6バイト) 3) R1チェックとDATA TOKENチェック 4) データを1バイト読出す毎にホスト(MMC.exe)へ送信。 eMMC 目前支持 1Bit / 4Bit /8Bit Command classes: Class 0 (basic) Class 2 (block read) A. CMD17 单个 block 读. B. CMD18 表示多个 block 读。 如果 Media <=2GB 则 Data address 32Bit byte address. 如果 Media > 2GB,则 Data address 32Bit Sector address. Class 3 (block write) A. CMD24 表示单个 Block 写。 In the non protected mode the CRC bits of t h e SPI mode supports single block read operation only command, response and data tokens are still (MultiMediaCard CMD17). Upon reception of a required in the tokens however, they are defined valid read command the card will respond with a as “don’t cares” for the transmitters and ignored response token followed by a data token in t h e by the receivers. eMMC Size: 4GB Number of days used: 365 Hours per day: 8 Max P/E cycles: 3000 Number of blocks per cycle: 20 Size of block: 4KB Number of writes per second: 1. I calculated 14.9 years endurance by taking the total number of bytes written per year and dividing it by (eMMC size x Max P/E cycles). I calculate endurance at the end of the file. 一つはarasanのipであるsdhci(emmc)で、もうひとつがsdhostです。 raspberry pi 3ではsdhostがsdカードスロット、sdhci(emmc)がwi-fiチップに接続されています。 sdカードを読み書きする場合はsdhostの方が性能が良いらしいです。 One great thing about MMC is the Boot Operation Mode.

Hi. I see from the specs for SD and MMC cards that the time from a read block command is sent and the response is received until data actual is ready for reading, named Nac in timing constant definitions table, must be calculated from the TAAC and NSAC fields in the CSD register to ensure proper readback of data. emmc/sd read error, cmd17, status=0x1df20df retry read, count: 5 info->magic = info->version_major = 1 info->version_minor = 0 info->slots[0].priority = 15 Computer-On-Modules - COM COM Express Mini Type10 module with Intel Atom x7-E3950 quad core processor with 1.6GHz core frequency up to 2.0GHz, 2MB L2 cache, 8GB 1866MT/s DDR3L onboard memory and 16GB eMMC onboard flash.

The original MMC was an actual flash memory card, the forerunner of the Secure Digital (SD) card. However, eMMC is not a card, but a JEDEC standard ball grid array. Hi, I test FSL sdmmc on OM13092 LPCXpresso54608 using sdcard_polling example (SDK 2.2.0). I have found it fails on SD_Read() / SD_Write() a single 512-byte sector with the microSD card: ATP 512MB Industrial Grade (AF512UDI AML 16020015 161316M83ENM E1606BA). I've also tried with decreased busClock... Thus CMD0 = 0000 and CMD39 = 100111. Neither of those, however, match adding 0x40 to anything. It does seem to make sense, though, if you take the command number (CMD1) convert it to hex (0x01) and add that to 0x40 (=0x41). If that is the case, a CMD17 would be 0x11 + 0x40 = 0x51, which matches sparkfun's definitions and which is what I used.
