歡迎光臨我的博客首頁個(gè)人資料日志圖片視頻(測(cè))好友博客群日志設(shè)置f2812 flash配置寄存器的等待周期數(shù)的理解
分類:默認(rèn)欄目一般而言，為了將運(yùn)行在f2812
flash內(nèi)得程序代碼以最快速度運(yùn)行，需要設(shè)置flash配置寄存器的等待周期數(shù)，而“設(shè)置flash配置寄存器的等待周期數(shù)”的這段代碼是不能在flash內(nèi)部執(zhí)行的，這樣就會(huì)出現(xiàn)兩種實(shí)際的配置方式：
一種是2812系統(tǒng)無外擴(kuò)程序存儲(chǔ)器，此時(shí)程序只能寫在2812內(nèi)部得flash區(qū)，程序運(yùn)行開始后，需要將“設(shè)置flash配置寄存器的等待周期數(shù)”的這段代碼用數(shù)據(jù)復(fù)制的方式復(fù)制到內(nèi)部sram區(qū)，比如
L0 區(qū)，然后使用跳轉(zhuǎn)指令跳轉(zhuǎn)到L0
區(qū)“設(shè)置flash配置寄存器的等待周期數(shù)”的代碼進(jìn)行flash配置寄存器的設(shè)置，設(shè)置完成后再使用跳轉(zhuǎn)指令跳轉(zhuǎn)到flash程序區(qū)執(zhí)行正常的功能程序。這樣以后的flash內(nèi)的代碼就會(huì)以最快速度運(yùn)行。
還有一種是2812系統(tǒng)外擴(kuò)了部分“引導(dǎo)”程序存儲(chǔ)器，“設(shè)置flash配置寄存器的等待周期數(shù)”的這段代碼放置在外擴(kuò)的“引導(dǎo)”程序存儲(chǔ)器內(nèi)，而其他的所有程序代碼都放在2812內(nèi)部flash區(qū)，系統(tǒng)復(fù)位后，首先運(yùn)行外擴(kuò)的“引導(dǎo)”程序存儲(chǔ)器內(nèi)的程序，一旦完成了對(duì)內(nèi)部flash配置寄存器的設(shè)置后，即跳轉(zhuǎn)到flash程序區(qū)執(zhí)行正常的功能程序。
正如上述，對(duì)2812外部接口XINTF配置寄存器的設(shè)置代碼，也是不能在“外部”程序代碼區(qū)進(jìn)行的，為了實(shí)現(xiàn)對(duì)其的正常設(shè)置，可仿照上述辦法進(jìn)行相關(guān)操作。

分類:默認(rèn)欄目用的是CCS2.20版本提供的SDFLASH,設(shè)置好SDFLASH后,主要是要將需要下載的.out文件寫進(jìn)去.
關(guān)鍵在于在線仿真時(shí)的cmd文件要加以更換成新的.使用的是:
-o .DebugPULSE_AD.out
-m PULSE_AD.map

然后把lib文件替換成:rts2800_fl040830.lib
就可以啦.
希望你也成功!!!
本人qq: 15007807 歡迎以后交流.
點(diǎn)評(píng)：
FLASH不用分這么細(xì)的,編大一點(diǎn)的程序會(huì)有麻煩
以下是本人做過的某項(xiàng)目CMD文件
