Abstract:Embedded Linux operating system is an embedded operating system based on Linux, which has been widely applied in the field of personal mobile phone, super TV, car electronic products and aerospace. The device driver plays an important role in the kernel. It is a bridge between the kernel and the peripheral devices. In this paper, based on the ARM processor we analyze the general steps of the development of embedded Linux operating system MMC device driver. Then taking the Beagle board-xm development board as an example to analyze the development process of MMC driver in detail, and realizing the support of the kernel to the mmc2 port and the mmc3 port.
