Obviously, we need to execute the ARM assembler first, and then the assembler jumps to the C program, but the compiler does not know whether to put the C code snippet or the arm assembler code snippet first, so we need to tell the compiler how to compile and connect. There is an LDS file in which the contents of the file determine the location of each code snippet in the program, and you can see how the file is passed to the compiler in the following makefile file.3. lds file/******************

The following bare metal program is based on gt2440 and the compiler is a arm-linux-gcc-4.4.3. Program structure: This program only has one SPI. s file. Program process: first, the power-on Reset enters the reset exception. In the reset exception, call the subroutine to close the watchdog, initialize the system clock, initialize the serial port, and finally call SPI to send data, the data sent by SPI is spe

The first part is to play bare metal in pcduino3. This process allows us to better understand embedded systems and be familiar with the platform we use.

For any hardware module design, the first step is to first understand the hardware itself, and then start the program software design. Because of the DM9000 chip document content, to drive a good network card, it takes a long time, especially for beginners more difficult, so you can refer to the Linux kernel code in the network card driver, porting it to bare-metal programs. The detailed procedures for DM90

Recently, I started to learn about the bare metal driver in the book Wei Dongshan. when running the code in the SDRAM, I found that it could not run correctly. the method I downloaded was to run the program through the D command of the supervivi provided by mini2440. Now, I think we have made many mistakes. Wei Dongshan's book emphasizes more than once that these bare
