用IAR如何把程序下載到430單片機(jī)指定存儲(chǔ)單元中

具體的lnk430G2553.xcl文件內(nèi)容見下面，里面定義了430單片機(jī)Flash中不同區(qū)域物理地址范圍。

// Description
//

//
// Usage:
//
// xlink [file file ...] -f lnk430g2553.xcl
//
// -----------------------------------------------
// Device summary
//

//
// Core: MSP430
//
// Interrupt vectors: 16
//
// Peripheral units: 0-01FF
//
// Information memory (FLASH): 1000-10FF
//
// Read/write memory (RAM): 0200-03FF
//
// Read-only memory (FLASH): C000-FFFF
//

// -----------------------------------------------
// Segments
//

// -------------------------------------
// Data read/write segments (RAM)
//

//
// segment Usage
// ------- --------------------------
// DATA16_Z Data initialized to zero
// DATA16_I Data initialized by copying from DATA16_ID
// DATA16_N Data defined using __no_init
// DATA16_HEAP The heap used by malloc and free
// CSTACK Runtime stack
// TLS16_I Thread-local storage for main thread
// (require custom runtime library)
//

// -------------------------------------
// Program and data read-only segments (FLASH)
//

//
// segment Usage
// ------- --------------------------
// DATA16_C Constant data, including string literals
// DATA16_ID initializers for DATA_I
// INFO Information memory
// INFOA Information memory, bank A
// INFOB Information memory, bank B
// INFOC Information memory, bank C
// INFOD Information memory, bank D
// CSTART Program startup code
// CODE Program code
// ISR_CODE Program code for interrupt service routines
// DIFUNCT Dynamic initialization vector used by C++
// CHECKSUM Checksum byte(s) generated by the -J option
// INTVEC Interrupt vectors
// RESET The reset vector
// TLS16_ID Thread-local initializers for main thread
// (require custom runtime library)
//
// Notes:
//
// * The INFOx and INFO segments overlap, this allows data either to be
// placed in a specific bank or anywhere in the info memory.
//
// * The INTVEC and RESET segments overlap. This allows an application to
// either use the reset vector provided by the runtime library, or
// provide a reset function by defining an interrupt function associated
// with the reset vector.
