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

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

Based on the PowerPC platform U-boot porting, the porting of the Linux kernel is as follows:1. Modify the top level makefileARCH = PowerPCCross_compile? = powerpc-linux-gnu-2.

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

Linux general technology-Linux programming and kernel information, which is a strange problem of PowerPC kernel transplantation, is described below. How to port a PowerPC-Based Kernel My system is based on mpc3167, the kernel is using a linux-2.6.10, u-boot version is 1.1.5, Use tftp to download the uImage to the target board. After decompression, the serial port is not printed. The following content is di

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

I386 = intel 80386. In fact, i386 is generally used as a general term for Intel (Intel) 32-Bit Microprocessor Amd64, also known as "x86-64" or "x64", is a 64-bit computer processor architecture. It is based on the existing 32-bit X86 architecture and developed by AMD. The CPU of the server that uses EPIC technology for IA64 intel64-bit processor is anteng itanium (development code: Merced) PowerPC is a type of CPU with a balanced architecture. Its

Recently, the boss asked me to introduce the experience of BSP development at the weekly meeting.Because there are foreigners in the group, they must also speak English.It's a great opportunity to practice English.It is expected to be an hour and a half, but I always want to talk more about it. Otherwise, how can I make it clear that BSP is so advanced in more than an hour?This is the first time I have worked on a workshop in the group, so I have paid more attention to preparing for it for a few

1 PowerPC BSP Customization 1. The main function of BSP is to configure the system hardware to make it work normally and complete data interaction between the hardware and the software, provides a hardware-independent software platform for OS and upper-layer applications. Therefore, from the execution point of view, it can be divided into two parts: ø hardware initialization and operating system boot routine during the startup of the target system, wh
