OpenWRT (RT5350) By default enables a serial port (Uartlite), as the console port, another serial port (UARTF) and Gpio multiplexing.In the process of finding data, it was found that the concept of device tree was used in the new kernel, and DTS files were used to describe all the resources of the Soc.For the RT5350 platform, there are several system-related configuration files:1, ~/openwrt/build_dir/target-mispel_24kec+dsp_musl-1.1.10/linux-ramips_rt
Linux Device Tree in my eyes (Basic specification overview)
Overview of basic specificationsData transmission (Device tree syntax) is the Device tree source file. To facilitate reading and modification, data transmission uses the text format. DTC (Device tree compiler) is a small tool responsible for converting DTS to DTB (Device tree blob ). DTB is the binary form of DTS for machines. In use, we first modi

what exactly is dts/pts in the video stream? DTS (decoding timestamp) and PTS (display timestamp) are timestamps of the decoder relative to the SCR (System reference) when decoding and displaying the frames, respectively. SCR can be understood as the time when the decoder should start reading data from disk. Each p

First of all, the distributed server must establish a connection with the database server, can be implemented through the ODBC interface, this article is not described, the following to describe how the client through the distributed server to access data.

Managing backups of SQL Server objects
Backing up data and transaction logs

You can use the SQL Server Business Intelligence Studio tool to create an Integration Services project and create a DTS package, this package can handle very complex data mining work. If the source is mssql and the target is oracle, you can use the transparent gateway of oracle ). Here, I set up to extract data from oracle and insert it into the MSSQL table recruitment corresponding to the new website. In this way, the integrat
The Linux kernel introduces the concept of the device tree starting from 3.x, which is used to separate the driver code from the device information . Before the device tree appears, all specific information about the device is written in the drive, and once the peripheral device changes, the driver code is rewritten. After the introduction of the device tree, the driver code is only responsible for processing the driver logic, and the specific information about the device is stored in the device

In the process of using SQL Server, the export of data, import is an extremely common operation because of the frequent need to centralize data from multiple different locations or to replicate data to multiple locations. We can use the bcp command to do this, but remember that the command format for BCP is a pain in the neck, Although you can view the Help files, we need powerful and simple tools to do this, and Data Transformation Services DTS provi
