We often say that flash memory is just a general term. To be precise, it is commonly known as non-random access memory (NVRAM). It features that data does not disappear after power failure, therefore, it can be used as external memory. The so-called memory is a volatile
Design of starting U-BOOT from nand flash memory
Introduction
As embedded systems become increasingly complex, the demand for large-capacity data storage becomes increasingly urgent. However, hard disks cannot be widely used due to the low power consumption, small size, and low cost requirements of embedded devices. Nand
For many consumer audio and video products, NandFlash MemoryIt is a better storage solution than hard drive, which is particularly evident in low-capacity applications with a size not more than 4 GB. As people continue to pursue products with lower power consumption, lighter weight, and better performance,NandIt is proving very attractive.

video data from the specified memory space. The encoded data can be stored locally or remotely, or sent to the network using the RTP protocol.The entire process is coordinated by the ARM core. In order to improve efficiency, a large number of DMA operations and the continuous storage space allocated by the cmem module are used.
