Eabi (Embedded Application binary Interface), binary interface of embedded applications.
AbiDefinition
Abi describes the underlying interfaces between applications and the operating system, between applications and libraries, and between application components. Abi allows compiled target code to run in a system compatible with Abi without any changes.

ARM processor status
The ARM microprocessor generally has two working states and can be switched between them:
The first type is the arm State. At this time, the processor executes the 32-bit arm command;
The second is the thumb State. At this time, the processor executes the 16-bit half-aligned thumb command.
During t
There is a lot of information about mplayer porting to the Internet, but it is confusing. Here, I have made a detailed summary about mplayer. Before doing this, it is best to decompress the source code package and check the configuration through./configure -- help.
The decoding library is already provided on x86 Linux, and you do not need to install the decoding library. However, the file system of the ARM platform does not have a decoding library. Yo
I have tried it many times in ubuntu10.10 and Red Hat Enterprise 6, and there are compilation errors! The final change is to miniora 9 in the mini2440 user manual, which indicates that the establishment of the development environment is related to the system. Some online users say that the GCC versions of the two systems are too new, but I tried the GCC compiler of the earlier version, the problem persists! Refer to the arm development environment for

support for the crossover environment, providing additional functionality to facilitate the development of embedded applications.
Click Next to the "Select Configurations" page, and we take the default, direct next step, to the "Cross GCC Command" setting. Here we can fill in the Cross compilation tool chain of the prefix and path, such as:
Cross compiler prefix:arm-arago-linux-gnueabi-
Cross compiler path:/data/linux/ti-sdk5/linux-devkit/bin
The example above is the cross compilation package
-Vic in armA:If the code is run in the On-chip RAM and the application needs to call the interrupt, the interrupt vector must be re-mapped to the flash Address 0x0. This is done because all the abnormal vectors are located at the address.0x0 and above. This is achieved by configuring the register memmap (in the system control module) to the user Ram mode. User code is connected to enable the interrupted vector table to be loaded0X4000 0000.

However, after reading some discussions on the internet, I found that the original knowledge is not popular, and it is my fault. In addition, I think understanding these things is helpful for iPhone programming (not just for those who like neon).
