key function are debugged according to the Uboot initiation process. Ensure that the uboot normally starts into the command line.(3) separate debugging for each module driver. So I modify the boards.cfg, modify the configuration file, determine the first address of the code snippet, memory header address and other basic elements. Expectations can be directly compiled. But after looking at the link script for the ppc460s processor, I think the problem is a little more complicated than I thought

platform hardware device information, search the matching setDriver and bind the driver to the device.In embedded PowerPC, system boot code, such as U-boot, is generally used instead of open Firmware.The early u-boot used the static data structure in the include/asm-ppc/u-boot.h struct bd_t to pass the basic information of the BoardPass to the kernel, and the rest is handled by the kernel. Such an interfac

This section describes part of the PowerPC-based second-stage Linux Startup Process. MMU initialization involves a large amount of content and a large amount of code. This section continues to describe the MMU hardware initialization and final MMU enabling process. Before getting started, I first pointed out an error in the previous article. When I introduced the RFI instruction in the mmu_off function, I thought it was an interrupted return, but then

Linux has always been very good at hardware support, many of the old and all because of the Linux can be supported by the Linux operating system. However, the author recently learned that due to the user community and the frequency of the relationship of multiple Linux distributions have begun to quietly give up support PowerPC. As a result, PowerPC users will lose support for the latest mainstream Linux (p

The configuration file is here. Taking nor flash mx29lv160bt as an example, the development tool is tornado2.2 for PPC. To include the trueffs File System in the VxWorks image, you must first define include_tffs In the config. h file. This allows the VxWorks initialization code

With the development of PowerPC, the use of PowerPC architecture of the processor has formed a huge family, in communications, industrial control, aerospace defense and other requirements of high-performance and high reliability of the field has been widely used, is a "noble chip." At present, there are few Chinese materials to elaborate the PowerPC family pedigr

Recently, a FPGA was added to the PowerPC board, and the PCI-e was debugged when a PCI-E was used to connect the board. Since VxWorks itself has already written the driver, it can be called directly during use, but soon the problem arises: at first, the MMAP method was directly used to map the FPGA bus to the application's memory space and try to read and write. This method is relatively simple and does not need to be copied between the kernel and the

Advantages of PowerPC over arm: With its outstanding performance and high integration and advanced technology, PowerPC chips are used in network communication applications, industrial control applications, home digitalization, network storage, military fields, power System Control is widely used. because PowerPC is cheaper than arm devices Tools are pirated every

Before learning about the Interrupt Processing Mechanism, let's take a look at the interrupt source of PowerPC. Here we use the e300c3 kernel. From the perspective of the e300 core, the interrupt source can be divided into exceptions and external interruptions, exceptions are generated by the e300 kernel, such as illegal commands or TLB Miss during memory access. This situation is too complicated. If we do not go into the details, the interruptions me

Attention:Some operations may not cause the hardware to automatically perform contextual synchronization. For example, when we pass the tlbwe directiveWhen updating the Utlb page table, the hardware does not automatically perform contextual synchronization, that is, the shadow register is not automatically invalidatedCache (if there is a page table in the shadow cache that has already been invalidated, if there is a newMay cause an unknown problem); If you want to make the update

During this period of time, we need to get the debugging and driver development work related to PCI Express. The old rule is that we should first look for information on the Internet. This kind of stuff is quite rare and we have already bought a book, I plan to summarize it by myself. This article describes how to configure the PCI bus in PowerPC. PowerPC uses a mechanism called FDT flat device description

PCI bus specifies the bus transaction that accesses the configuration space, which is called the configuration read/write transaction. Unlike the storage access transactions that use the storage address for access, the idnumber is used for addressing access to the PCI configuration space. The ID of a PCI device consists of the bus number, device number, and function number. For Embedded PowerPC applications, the PCI design is often very simple. The PC

Any net earning project, want to make money we need to know the reason that will lose money clearly. As a webmaster to want to make money through PPC advertising, first of all we also need to understand why some AdSense operations PPC advertising will be beyond their means. There may be many ways to make a profit, but the reasons for failure often come mainly from three or four aspects. In the past 2012 yea
