First, s3c6410 a more typical development board, integrated with a variety of components. It is a low power, cost-effective RISC processor by Samsung, which is based on the ARM11 core and can be widely used in mobile phones and general processing applications. Serial communication means that the Linux driver output debug information can be displayed in some way by using the

With the efforts of the Hellox development team and the support of Winzent Tech Inc. (headquartered in Stockholm, Sweden), the latest version of Hellox V1.78 has been successfully ported to the Minnowboard Max Development Board. The relevant source code has been posted on GitHub (Github.com/hellox-project/hellox_os), and interested friends are welcome to download
device data input
(2) Mosi-master device data input, output from device data
(3) sck-clock signal generated by the master device
(4) CS-enable signals from the master device
Among them, CS is to control whether the chip is selected, that is, only when the chip selection signal is a pre-defined enable signal (high potential or low potential), this chip operation is effective. This allows connecting multiple SPI devices on the same bus.
I have introduced so much about the SPI bus theory.
The Linux driver cannot be tested with only a piece of s3c6410 ARM11 processor chip, but it must also be developed on the processor's PC on the Linux driver, recompiled into the arm architecture of the Linux driver module, but in the end it will be tested on the Development Board. The most popular is based on the Samsung s3c6410 ARM11 architecture of the Development

and from the internal address. A very small part of the 64 Mbit SDRAM on the Development Board is actually used by the NIO system, and the rest are idle. Do you think it is a waste. In fact, in some cases, we can use this part of resources. For example, in a system, we need to cache the data received by peripherals, we can use this part of idle SDRAM space for processing.
in C, if we want to receive rela
1. Brief DescriptionThe debugging and flash burning functions of jlink are powerful, but it is difficult to perform flash operations on S3C2410 and S3C2440: You need to set SDRAM when burning or flash; otherwise, the speed is very slow; burning and writing NAND flash can only be achieved theoretically, but no one has implemented it directly.In this article, an indirect method is used to burn or write non-NAND flash on the S3C2410 and S3C2440 development

Altera officially has a de2 Development Board, which has rich resources and complete peripherals. It uses ten-layer circuit board design, and the price is naturally high. I made a piece based on the principle diagram, called diy_de2 Development Board. The
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:

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
