- SanDisk 微型 SD 卡 32GB
- Transcend MicroSD 读卡器
- Ubuntu 16.04.2
在安装期间motioneyeos我注意到它们/dev/mmcblk*不在那里。我检查了一下lsusb -a，发现读卡器正在被检测到：
Bus 003 Device 007: ID 8564:4000 Transcend Information, Inc. RDF8
我检查了dmesg一下：
dmesg | grep sdb

我还检查了内核.config（我使用的是 4.4.0-78-generic）并看到以下内容：
CONFIG_MMC_BLOCK=m
CONFIG_MMC_BLOCK_MINORS=8
CONFIG_MMC_BLOCK_BOUNCE=y
CONFIG_SDIO_UART=m
CONFIG_MMC_SDHCI=m
奇怪的是，读卡器被视为/dev/sdb。例如命令的输出udisksctl status：
TS-RDF5 SD Transcend TS37 000000000039 sdb
fdisk -lu输出：
Disk /dev/sdb: 29.7 GiB, 31914983424 bytes, 62333952 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x197087fd
奇怪的是 Disklabel 类型是“dos”？
我还对以下模块进行了 modprobe：
modprobe mmc_core
modprobe mmc_block
modprobe sdhci
我拔下卡并重新插入并看到以下内容dmesg：

有谁知道为什么这不起作用吗？
答案1
我能够使用 Etcher 将图像写入 SD 卡。我现在能够启动 motioneyeos 图像。
