scatter分析(国外英文资料) Problem analysis: The distributed load description file is a text file that describes the memory map of the target system to the linker. It is not important to describe the files extension if you use the linker by command. Scatter load file specification: 1) the loading address and maximum size of each loading area; The properties of each loading area; The execution area derived from each loading area; The execution address and maximum size of each execution area; 5) the input section of each execution area. From the format of the description file, you can see the hierarchy of the loading area, the execution area, and the input section. Problem solving: Program compile and generate the target file, will link into an executable file, the process used to disperse load file, it decided to executable code stored in the storage location, in the complicated programs (such as VIVI to Linux kernel boot) is very important. The following is an example of a simple distributed load file: ; * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * ; * * * * - Loading Description File generated by uVision * * * ; * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * ; Run in the Flash LR_ROM1 0{; The load region ER_ROM1 00x0200,000 {; The load address = execution address (RESET, + First) * (InRoot $$Sections) . ANY (+ RO) } RW_RAM1 0x300000000x4000000 {; RW data ANY (+ RW + ZI) } RW_IRAM1 00{ ANY (+ RW + ZI) } } Routines, in the above code, starting at address 0 stored in the first place and will RESET the procedures section, and the read/write data from address 0 starting store. To spread the period of load file name (for example, LR_ROM1 ER_ROM1, etc.) can be any name. ADS distributed file syntax: ; Loading domain writing format: ; Loading domain name is the maximum lengt
