lpc2148點(diǎn)燈 去了n小時(shí)

剛開始用ulink發(fā)現(xiàn)驅(qū)動(dòng)始終安裝不上，網(wǎng)上搜索n久未果，罷也！后面選擇jlink發(fā)現(xiàn)問題多多，但是出現(xiàn)以下數(shù)據(jù)仿佛看到希望，畢竟可以讀到內(nèi)核的數(shù)據(jù) ARM7TDMI-S Core 電壓 3.332V

繼續(xù)探索：

check blank verify 等檢查會(huì)都會(huì)出現(xiàn)問題，成功次數(shù)只是偶爾！于是想可能jlink是驅(qū)動(dòng)不穩(wěn)定問題！又開始網(wǎng)上搜索進(jìn)入各大論壇網(wǎng)站，終于找到了jlink4,34版本驅(qū)動(dòng)！發(fā)現(xiàn)問題依然不穩(wěn)定.....以當(dāng)年的脾氣早就火了！但還會(huì)慢慢摸索終于找到問題，默認(rèn)仿真速率是1000k，改為50k的時(shí)候不穩(wěn)定點(diǎn)現(xiàn)象明顯好轉(zhuǎn)！后面改為20k基本百發(fā)百中.....
