well, therefore, the communication protocol of the Android elevator advertisement machine uses the CAN bus. Therefore, we need to always use the CAN bus. For Linux drivers with several can Bus protocols under drivers/net/CAN/, we choose the freescale Flexcan. I will introduce the process of compiling the Android system and setting up the development environment in another blog. Set the Flexcan driver when running make menuconfig during Android kernel

Get a board, one of the most important thing is to see the circuit diagram and datasheet.This is really important, first you need to know what the CPU architecture is, ARMV7?ARVMV5, or other, which company's chip? is Freescale or Ti or MTK, or samsung,hisilicon or some other what chip, now the CPU data manuals are all relatively full, it is easy to find relevant information on the official website, but also to find some other useful information on the

-compiler tool is released earlier, From 2005 onwards until now. Linaro is a non-profit company that is jointly developed by ARM, Freescale, IBM, Samsung, St-ericsson, and ti to develop common software for a single chip (SoC) platform for different semiconductor systems. Linaro was established in 2010, and in November released the first edition of Arm cortex-a as the core SoC for performance optimization software tools.ARM-NONE-LINUX-GNUEABI-GCC as fo

ARM-LINUX-GNUEABIHF-GCC is an arm cross-compilation tool launched by Linaro based on GCC. Code that can be used to cross-compile all aspects of an arm system, including bare-metal programs, u-boot, Linux kernel, filesystem, and app applications.ARM-LINUX-GNEABIHF-GCC, similar to Codesourcery 's ARM-NONE-LINUX-GNUEABI-GCC, can be used to compile all the link codes based on the arm platform, Codesourcery The cross-compilation tool was released earlier, starting from 2005 until now.Linaro is a non-

Recently, a product was developed using the Freescale i.mx6q four core processor based on the arm cortex-a9 core, when compiling Ltib on Ubuntu 12.04, there was a problem with zlib not found (the various library files must have been installed before).The error message is as follows:=============================[Email protected]:~/imx6/l3.0.35_4.1.0_130816_source/source/ltib$./ltibLtib cannot be run because one or more of the host packages needed to ru

At the programme seminar, two programmes were very different. One uses a general-purpose chip, such as a DSP,ARM9,FPGA, a dedicated chip, such as a copy-and-scan facsimile integration. There are advantages and disadvantages to each of the two schemes: Using a general-purpose chip, the advantages are: 1. Easy to buy chips. Not only depends on one model. Any MCU can be. NXP Arm chip can, Atmel also can, Freescale also line, unlimited models. 2. High por

with the device using this compatible value.The value of the compatible is a list of strings, the first string in the list accurately describes the device in the format "For example, the Freescale MPC8349 Soc has a serial device that implements National Semiconductor ns16550 register interface. Therefore MPC8349 serial device compatible attribute is: compatible = "Fsl,mpc8349-uart", "ns16550". Here, Fsl,mpc8349-uart specifies the exact device, ns1655

APIs and tools-from SE Embedded development to server-side Java EE development. There will be only one type of Java developer in the future. Other elements of the Java Platform Strategy include synchronous Publishing (now available for download in the Java 8 Preview) and working with partners (ARM, Freescale, and Qualcomm) to make Java a first-class citizen on a chip. In order to be able to simply migrate and extend the Java Embedded, Oracle launc

The importance of file systems for embedded systems is self-evident, with file system Management data and peripherals becoming much more convenient, while simplifying application development. Today, let's take a look at the Spi_flash file system to see how the Fatfs file system is ported and used. The materials to be prepared are: (1) Fatfs File System source code (click here to download the latest Fatfs source). (2) Single-chip microcomputer platform one (larger memory better).
