oob data

  I am reading the code for writing yaffs2 in uboot. I have some questions.Enter the command, run do_nand, and then run nand_write_opts Int nand_write_opts (nand_info_t * meminfo, const nand_write_options_t * opts){..........................

Through the above section, for NAND flash, each page, corresponding to an idle area (OOB), this region is based on the hardware characteristics of NAND flash, the data is error-prone when reading and writing, in order to ensure the correctness of

Oob sms Overview OOB (out-of-bound) text messages are also called out-of-band text messages compared with the actual business channels of mobile applications. OOB is invisible to terminal mobile phones, the terminal application can intercept the OOB

For example, Samsung k9f1208u0b has a data storage capacity of 64 MB and uses block-page storage management. 8 I/OThe pin acts as a multiplexing port for data, addresses, and commands. Chip storage layout and features:A piece of NAND Flash is a

The size of each page of NAND Flash is (512 + 16) bytes (there are other formats of nandflash, such as the size of each page (256 + 8), (2048 + 64), etc ), the 512 bytes are the data storage area, and the 16 bytes are called the OOB (Out ofband)

The Out Of Brower transport layer protocol uses out-of-band (OOB) to send important data. If the communication party has important data to notify the other party, the protocol can send the data to the other Party quickly. to send the data, the

You must add a digital signature to the OOB public network deployment to automatically update the instance. The following method is available: 1. Open Visual Studio Command Prompt in Visual Studio Tools as an administrator and run the following

This article describes the system calls to read and write data on a network connection, in three parts: The first section describes the four system calls used to send data: Write,writev,sendto and sendmsg. The second part introduces four systems for

Next, I will explain the implementation of the SATA host protocol's physical layer. Is the physical layer structure given in the standard SATA protocol document. It contains the control module, clock data extraction unit, synchronous character
