Use of keil: Create a new Project-EEWORLD

Collect

Create a new project--->New folder----->Put the new project in your own folder------>Select the development board------>Add the driver file of the development board- --->main function

The project grouping is basically as shown in the figure. S3C2440.S is the bare board driver of the 2440 board. It helps us initialize a lot of things. Without it, we cannot write programs in it.

Of course, you can also write the bare board driver yourself, but we’ll talk about that later.

Secondly, the program starts executing from the main function.

Some commonly encountered problems:

Error: L6218E: Undefined symbol Image$$ER_ROM1$$RO$$Length (referred from s3c2440.o).
 Error: L6218E: Undefined symbol Image$$RW_RAM1$$RW$$Length (referred from s3c2440.o).
This problem occurs: Fill in Options for targets----->Asm------>Define:

__EVAL



There is another problem, I forgot what it is. There will be 6 ERRORS first. The solution:

Options for targets------>Linkers------>Use Memory xxxxx is unchecked
Then clear the contents of the scatter file

linux-2.6.32 transplanted on mini2440 development board - transplanted Nand driver and modified partition information

Editor: The transplantation of NAND in Linux is not as complicated as imagined because it uses MTD technology. 1 Nand Flash types supported by Linux-2.6.32.2 kernel Linux2.6.32.2 has built-in most Nand Flash drivers. The supported Nand Flash types are defined in the linux-2.6.32.2/drivers/mtd/nand/nand_ids.

Make Ultra Edit and Keil more closely integrated

Engineers who work on single-chip microcomputers generally like to use Ultra Edit editor, because it can highlight the programming language keywords in color and can also support Chinese well. Although Keil can also highlight the keywords in color, it does not support Chinese very well. In addition, Ultra Edit editor a

Summary of methods for setting header file paths in keil4

Personal Records: I feel the relative path is more convenient. Keil looks for header files in the directory where the project file is located. The relative directory of the header files is relative to the .uvproj file. My current personal habit is Create: Doc, Listing, Output, Project, User folders Doc for doc

S3C2440 bare metal learning [2] - LCD driver principle and code analysis [Part 2]

Let's take a look at the lcd.c file in 2440test static void PutPixel(U32 x,U32 y,U16 c) { if(x SCR_XSIZE && y SCR_YSIZE) LCD_BUFFER = c; } It is easy to find that the function of displaying a single pixel on the TFT LCD is actually very simple. It seems that only LCD_BUFFER = c is needed. Let's analy
