I am using the utu2440 Development Board. The Boot files of the Board include nboot1, nboot2, eboot, and wince kernel. The functions of these files are as follows:
Nboot1: S3C2440 for NAND Flash, you can run the code that can load up to 4 K. After nboot1 is started, nboot2 will be loaded from flash.
Nboot2: Read the wince kernel from flash, load

This section contains examples of how to create an Attribute Table and process notification messages.Create an Attribute Table
In this example, a new attribute table is created, which contains two pages: one is to set the font attribute of the Unit in the workbook program, and the other is to set the border attribute of the unit. In this example, the page (pages) is defined by filling in a pair of propsheetpage
First, it is usually assembly. Code : 0 is triggered by system reset at startup. Take code 2440 as an example to directly enter the FW. s file. In some BSP packages, the name of the assembly code is startup. S. The main operations are to set the CPU frequency (PLL), initialize RTC, set memory parameters, prepare to apply for Ram for the second stage of bootloader, and read the bootloader of the second stage into RAM, then enter the main function of the C code in

Most NAND bootloaders are divided into nboot and eboot. Code dependent on the CPU architecture is put in nboot, which is usually implemented in assembly language + C language; while eboot is usually implemented in C language, which can implement complex functions, in addition, the Code has better readability and portability.Nboot:

First, the introduction:
If you write a DOS application using a compiler such as turboc2.0/3.0 or borlandc3.x, writing an application in the form of a command-line argument is a very easy thing to do, as long as you add a few arguments to the main function main (), OK (int main ( int Argc,char *argv[],char *env[]) {}). It is difficult to write a command-line parameter relative to the assembly language, which uses the DOS prefix PSP (program Segment P
Osintexit function to activate the PENDSV interrupt when the interrupt exits, and the real task switch is implemented in the PENDSV interrupt routine.
The 3rd is to call Os_sched when a task switch is required, which calls OSCTXSW, while OSCTXSW activates the PENDSV interrupt, and the PENDSV interrupt routine completes the real task switch.
So all the task transitions are ultimately done by the PENDSV interrupt routine.
The interrupt priority of the PENDSV must be the lowest of all interrupts

Abstract: This article
Program And. when the EXE program is loaded, different memory images are obtained :. the com program has only one physical segment. The maximum length of the segment is 64kb :. the com program can only start at 100h of the Offset address. DOS pair. the length of the EXE file is not limited, so it is easy to organize large applications; and. in the EXE file, end start labels are used to describe the start point, push ds is used to save the

2.Thread, MSP
3.Thread, PSP
Ii. Exceptions:
1,There is a stack pressure process. If PSP is used when an exception occurs, it is pushed to PSP. If an exception occurs, it is pushed to MSP.
2,The LR value will be set based on the processor mode and the stack used (of course, the

COM file contains an absolute map of the program-that is, to run the program's accurate processor instructions and data in the memory, the MS-DOS loads the image directly by copying the file to the memory. com program, it does not make any changes. To load. com program, the MS-DOS first tries to allocate memory because
