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

When I wrote "getting started with the neon iPhone", I thought that the reader had a better understanding of the processor knowledge of iOS devices. 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). Even if you are using objective-C, even if you are not familiar with it, it will not affect your work, b

function pointers are the basis for implementing callback functions, which are the basis of C program architecture. So the importance of function pointers is self-evident. However, recently on the Arm Development Board test program, found that the function pointer can be compiled, but the runtime is always error. The following is one of the simplest test program source code.

Arm belongs to RISC instruction set, and x86 is representative of CISC instruction set, the result of compiler generation is more representative. Among them, parameter passing and return values are the most concerned parts of assembly/C mixed programming, especially in bootloader programming. In general, RISC tends to register to pass parameters, while x86 is passing parameters through the stack. The return value is achieved through the most efficient
"Single Arm Routing"
Function: Realize communication between different VLAN
Implementation method: Configure the Sub-interface, encapsulate different VLAN separately
"VTP"
Chinese name: Virtual LAN Relay protocol
Role: Unified Management VLAN
Implementation method: Configure a switch connected through a relay link in a domain
"VTP Precautions"
A) VTP can automatically update "domain name, version, revision number, trim, VLAN number, VLAN name"

-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.
