As mentioned above, the mobile phone industry is dominated by nor flash memory, and Flash memory chips are directly deployed on internal circuit boards, however, digital cameras, MP3 players, handheld computers, and other devices require that the storage media be replaceable. Therefore, interface standards must be developed to achieve connection. The flash card technology came into being. A flash card uses flash memory as its core storage device. In addition, it also

The SD card is in the same shape as the MultiMediaCard card and is compatible with the MMC Card interface specification. Note, h

There are many fat formats, the most common and familiar to readers are fat16 and FAT32. fat16 indicates that the File Allocation Table uses 16 digits, A 16-Bit Allocation Table can manage up to 65536 clusters (that is, the 16 power of 2), that is, a specified hard disk partition.

We performed this operation on the Ubuntu 5.01 system platform. Because Ubuntu does not allow root permissions by default, you must switch the sudo su root permission to the root permission for the operation. Otherwise, a message indicating insufficient permissions may appear. For details, refer to the Linux version description.
