说明:  基于dm642的flash烧写程序(不用ti的烧写工具flashburn) flash:sst39vf1601,1M*16bits 开发平台 ccs2.2 在自己开发的视频服务器上实现flash正确烧写及上电自举
(DM642-based procedures for the flash programmer (the programmer do not have ti tools flashburn) flash: sst39vf1601, 1M* 16bits development platform to develop in their own ccs2.2 video server realize the correct flash programmer and power bootstrap)

实现正确擦、写及上电引导测试(上电自引导gpio控制程序) 其中1级引导为8位模式(系统默认) 2级引导为16位模式,在bootloader中先进行emifa设置,ce1 设为16位模式 具体如下: emif_values: .long 0x00052078 ; GBLCTL .long 0x73a28e11 ; CECTL1 (Flash/FPGA) .long 0xffffffd3 ; CECTL0 (SDRAM) .long 0x00000000 ; Reserved .long 0x22a28a22 ; CECTL2 .long 0x22a28a22 ; CECTL3 .long 0x57115000 ; SDCTL .long 0x0000081b ; SDTIM (refresh period) .long 0x001faf4d ; SDEXT flash boot 0x00000000~0x00000400; gpio 0x00000400~0x00000ca0; u8 *src0 = (u8 *)0x00000000; u16 *dst0 = (u16 *)0x90000000; u32 length0 = 0xa0; u16 *src1 = (u16 *)0x00000400; u16 *dst1 = (u16 *)0x90000800; u32 length1 = 0x14b2; boot FLASH_SRC .equ 0x90000800;引导源地址 RAM_DST .equ 0x00000400;引导目的地址 COPY_LENGTH .equ 0x000014b1;设为所要循环的次数减1(word=16bits) RAM_Entry .equ 0x00000ba0;引导后用户程序入口地址 注:烧写程序与用户程序勿重叠,先load用户程序,再load烧写程序,ccs中执行的是最后load的程序,具体用户程序的烧写需根据其cmd文件map文件修改上述参数,src dst Entry等等
