Ubuntu 16.04.2 LTS找不到微型SD卡
提问于 2017-06-02 17:34:05
- SanDisk微sd卡32 sd
- 超越MicroSD读卡器
- Ubuntu 16.04.2
在安装动眼时，我注意到/dev/mmcblk*不存在。我检查了lsusb -a并发现读卡器正在被检测到：
Bus 003 Device 007: ID 8564:4000 Transcend Information, Inc. RDF8我查看了dmesg并看到：

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，读卡器被看作是/dev/sdb。例如，udisksctl status命令的输出：
TS-RDF5 SD Transcend TS37 000000000039 sdbfdisk -lu输出：
Disk /dev/sdb: 29.7 GiB, 31914983424 bytes, 62333952 sectors

I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x197087fd奇怪的是，磁盘标签类型是"dos“吗？
我还对以下模块进行了调制：
modprobe mmc_core
modprobe mmc_block
modprobe sdhci我拔出卡并重新插入，并在dmesg中看到以下内容：

我能够用Etcher将图像写入SD卡。我现在可以启动运动眼睛的形象。
