snapdragon development board

Recently, two jz4750 APUs development boards are required for trial. This is also the first contact. I encountered a lot of problems in the middle and finally spent a lot of time doing a good job. Here I will summarize all the process records (for the time being, I cannot upload a picture, and I will try it again if I have a chance ). This diary is divided into the following points: 1. hardware connectivity 2. Linux environment construction and kerne

When using GDB on the Development Board debugging, sometimes need to look at the source code, but the source code is too large, the development Board capacity is limited to pass through the SCP every time the development Board, or

Through the study of this chapter, I have a certain understanding of the test environment of s3c6410 Development Board, and have mastered the following knowledge points:First, for s3c6410 This development Board, it is a low-power, cost-effective processor, it is based on the ARM11 core.The difference between different

Update Development Board firmware The IDE contains the released board and sub-dedicated firmware. Follow these steps to update your board with IDE:(1) disconnect all power supplies (USB and 5 V power supplies ). Make sure no sketch is running on the board(2) Remove the SD c

The previous chapters mainly describe the installation and construction of the native Linux Android development environment and the porting of the Android system. This chapter focuses on how to install Android on the Development Board . Development boards are the main hardware devices for developing and learning embed

flash device number, you can use the command "NAND device" to view the specific Flash device information on the Development Board. Offset refers to the starting offset address of the kernel file in Flash. It automatically reads the end of the kernel image (processed with mkimage), so no read size is given. Example:Nboot 80700000 0 200000Tftpboot [LOADADDR] [[Host_ip:]filename] uses the TFTP protocol to boo

I. Overview 1. The display drive architecture of flisikar imx6: 2. Objectives: Because the sabrelite Development Board itself has provided LVDS interface, the target screen is LG's LP101WX1-SLN2, its main parameters are: Resolution: 1280*800 Color: 18 digits Color: 262 K Clock frequency: 69.3 M Hz 2. porting process 1. First, connect the screen interface to the LVDS interface of the sabrelite

I wrote an LED driver over the past two days and read many posts online. The idea is very clear at first, that is, first look at the circuit diagram and find that the LED lights are connected to the GPM port, Then, let's look at the data manual, first to gpmcon port write command words, let the GPM0-5 set to output, and then write data to the gpmdat port, in the GPM0-5 pin to pull low or pull high level, To control the LED lighting. 1. Circuit Diagram Obviously, the LED light is connected to th

Setting up the test environment for the s3c6410 Development Board describes how to install Android on the Ok6410-a Development Board. Development boards are the main hardware devices for developing and learning embedded technologies. To be tested on the

1. OverviewEmbedded system consists of hardware environment, embedded operating system and application, hardware environment is the hardware platform of operating system and application, it has different requirements depending on the application. The diversity of hardware platform is the main feature of embedded system, how to make the embedded operating system run effectively on different hardware platform is the key problem in the development of emb
