, the host! = Build when the compilation is cross-compilation. If no designation will run ' config.guess ' to detect;>>--prefix: installation directory; >>--help: view parameters;>>--target: This parameter is special, indicating the target platform name that needs to be processed, primarily in the context of program language tools such as compilers and assembler, if no value is specified using host. Generally used to compile tools, such as to the arm Development

Recently the classmate sent a Raspberry Pi, including an already packed Raspberry Pi Board (the Raspberry Pi box needs to be purchased separately), a power supply, and an SD card with a

a more complex input with timing. Here are two points to note: The SetMode is in BCM mode, and the pin used is the same as the BCM number corresponding to the pin graph. You can also set the physical PIN number to use SetMode (GPIO). BOARD). The input/output mode is input when receiving data/status relative to host or Raspberry Pi, output i²c I²c can be a bus to

the following two lines of code:http. Handle ("/", HTTP. Fileserver (http. Dir ("HTML")))http. Listenandserve ("0.0.0.0:8080", nil)Step 4: The target environment is modified to CROSS-ARM6, according to "Ctrl+b" compiled, the generated execution file is the source directory "Test", no suffixStep 5: Copy "Test" to your arm Development Board (Raspberry Pi Raspberry

-linaro-arm-linux-gnueabihf-raspbian-x64 are used for 64-bit machines. Each cross-compilation tool has a bin directory in the directory to enter, execute./arm-linux-gnueabihf-gcc-v to view the GCC version. I use ARM-RPI-4.9.3-LINUX-GNUEABIHF here because the GCC version on the board is now 4.9.3 3. Start compiling 3.1 Enter the Linux kernel directory: $ CD ~/RASPBERRY/LINUX-RPI-4.4.Y $ kernel=kernel7 $ make

SD Formatter, select the your SD card and format it. DRAG and DROP NOOBS FILES Once your SD card have been formatted, drag all the files in the extracted NOOBS folder and drop them onto the SD card Driv E. The necessary files would then is transferred to your SD card. When this process had finished, safely remove the SD card and insert it into your Raspberry Pi. First BOOT

Environment: Raspbian-stretch (2018-06-27)Raspberry Pi: 3 generation B Type1, Raspberry Pi equipment, need to be in the field can also have independent networking capabilities, it is necessary to use the Internet of Things module.The SIM868 communication module for micro-snow is used here, such as:2, will SIM868 insert

This project uses Raspberry Pi with ultra-low-cost software radio (SDR) hardware to receive tracking information sent from an airborne S-mode transponder outside millions of miles. The Raspberry Pi is equipped with a smart 3.5-inch TFT display to provide a convenient overvie

Ubuntu Raspberry Pi 2b cross compiling environment, ubuntu2b Generate executable code on another platform. Why is cross-compilation costly? One sentence: The last thing is. Sometimes it is because the target platform does not allow or cannot install the required compiler, and some features of the compiler are required. Sometimes it is because the resources on the target platform are poor, it is impossible t

package for the release. It generates a file with a name similar to "package-version.tar.gz" in the current directory. Package and version are the Am_init_automake (package, version) that we define in configure.in;>>make Distcheck: Generate and test the release package to determine the correctness of the release package. This action will automatically unpack the package file, then execute the Configure command, and do make to confirm that the compilation does not appear error, and finally promp

Buy Raspberry Pi 3, want to play through the serial console The results found that the serial port is not available This means that during the boot process, you don't see those strings printed, and then you can't use the serial console Checked the relevant articles on the Internet. The main reason is that the Raspberry Pi
