psp eboot

An important buffer contained in Eboot is called Driver Globals, which is used to share data between device drivers and WinCE OS. The startup parameter structure that is used in eboot is called the Boot Args, which is used to share some parameter information between the Eboot and the WinCE OS. Generally speaking, the boot args will be assigned or updated when the

OEM flash functions in wince eboot Address: http://blog.csdn.net/nanjianhui/archive/2008/11/12/3283072.aspx Author: arm-WinCE The Flash operating function is provided in eboot to burn the downloaded wince image to flash, which requires some flash-related OEM functions. These OEM functions are called in the blcommon module, that is, in the downloadimage function of the blcommon. c file. In the downloadimage

In the eboot of wince, there are some functions that belong to the OEM function of optional, which is optionally implemented. These functions are called in the Blcommon module, we need to implement them in the Eboot, and then assign the implemented function to the corresponding function pointer in Blcommon, so that the Blcommon module, when invoking these optional functions, Will first check whether they ar

It should be said that Bootpart is a Microsoft-provided module for partitioning, which can be used in eboot. But to tell the truth, I rarely use it, know that some vendors in the BSP to support this function, but also a part of the eboot, so or introduce. First look at the architecture, as shown in figure: In Eboot, Blcommon is at the top, as described previousl

Author: arm-WinCE In eboot, after you jump from startup. s to the C program entry, the program can be written in C language, which is much better. Generally, the C language entry is a main function, which may also be called another name. The bootloadermain function will be used in this main function, which is defined in the blcommon module. Generally, the main function is written as follows: Void (void) { // Common Boot Loader (blcommon) main routin

I just started learning wince and used the evc4.0 + pb5.0 + Samsung 2440 Development Board. The first is to change the startup screen of the eboot and kernel. After several days, the boot screen has been black. Later, I found that the screen was not lit, the screen must be lit and the image data must be 16 bits. Void s3c2440disp: initializehardware (void) in smdk2440/Drivers/display/s3c2440lcd) There are pins that need to be pulled up, and then the

In Eboot, from the STARTUP.S jump to the C program entrance, the program can be written in C language, so feel much better. The General C language entrance is a main function, may also be called other names. The Bootloadermain function is dropped in this main function, which is defined in the Blcommon module. The general main function is written as follows: void (void) { 　　// Common boot loader (blcommon) main routine. 　　BootloaderMain(); 　　// Shoul

The Startup.s file contains a startup entry function, which is the first entry for the eboot. This is the first function to be executed when the system is electrically or cold-booted. This function is written by assembly language, complete the initial initialization based on the hardware platform, that is, CPU related initialization, if necessary, can also be used to initialize the peripheral devices here. The function executes to the end and jumps to

General use Eboot Download wince image is through the network, refers to Ethernet, of course, there are also downloaded through the USB, but the network download is the most commonly used. In fact, the download work is done in the Blcommon module, it will call the Oemreaddata function to download the data, oemreaddata by the user to achieve, generally if the network download, Will call the Ebootetherreaddata function directly in Oemreaddata to read da

During the upgrade, you need a prompt to add a keyboard to control the magic horse. Therefore, we need to add this keyboard to eboot. Because this interrupt cannot be used in eboot, you can only use scan keys. The buttons are: Row: gpk8 ~ Gpk13 Column: gpl0 ~ Gpl4 (you only need to use one column here. Use gpl0, so there will be six buttons) Refer to the keyboard-driven keypad, Which is simplified here. I

WinCe6 EbootAdd boot Screen Yesterday I studied how to add a personalized screen when wince was started. After a long morning of hard work, either the screen or CE would not start ...... Finally, let's share some experience... The following two methods are generally used to add a boot screen to Wince: 1. Define a large constant array in the file, such as const USHORT ScreenBitmap [], copy the array to the corresponding buffer using the for loop condition where the image is displayed. 2. Store th

Eboot provides the ability to manipulate flash, and can burn the downloaded wince image into Flash, which requires some flash-related OEM functions. These OEM functions are invoked in the Blcommon module, which is called in the Downloadimage function of the blcommon.c file. In the Downloadimage function, the header of a generic image file is first downloaded and parsed. Then call OEMISFLASHADDR to determine the area where the image is located, if it

I have talked a lot about the methods for setting wireless routes. Today I will mainly explain how to configure wireless network parameters for PSP and some configuration problems. I hope this will help you. With the development of wireless routing technology, more and more devices have the function of connecting to the wireless network to facilitate resource sharing and system upgrade. A few days ago, I once introduced to readers of IT168 how to add

The main function of EBOOT calls BootLoaderMain (). Microsoft has fixed it. The development of EBoot mainly improves several functions called by BootLoaderMain. 1. relocate globals to RAMKernelRelocate (pTOC) 2. Init debug support. We can use OEMWriteDebugString afterward.OEMDebugInit () 3. initialize platform (clock, drivers, transports, etc) OEMPlatformInit () 4. call OEM specific pre-download function O

Unconsciously, it has been a long time to become a dual-host family. Looking at the online fans about PSP and NDS, they can't help but smile. Existence is the truth. PSP and NDS are the top machines on this Earth. This is a fact that no one can shake. Do those people are all fools, and only those who degrade are wise? Maybe not, right?I have the habit of writing tofu blocks. I have been using Dual Servers f

using the Beaver Nest to convert video files Why format to enable PSP support ? The All-in-one Video Converter is a video and audio format converter that is used by many netizens to facilitate the conversion of video format into a video format that can be imported into a player or video editing software. So, what can I do to convert video files to the PSP support using the Fox-socket Universal Video Convert

When you look at Nboot and Eboot source programs, you will find two types of addresses: Virtual Address and physical address. virtual address is the address you use in the program, the physical address is the actual address in RAM. In Bootloader, you can directly use the physical address. However, when WinCE is started, you can only use the virtual address. In Bootloader, a macro-defined function is usually used to convert each other, for example: # D
