標(biāo)題: a3p060 燒寫問題
我吧vjtag,vpump直接接到3.3V了。
出現(xiàn)這個(gè)錯(cuò)誤：
programmer 'FPBBALTLPT1' : Scan Chain FAILED.

是不是vjtag必須接上拉電阻？
vpump必須用電容?

如果需要，要多大的？

貌似我找不到 fpga/cpld應(yīng)該劃分到那個(gè)類別，5個(gè)主題好像都不太合適。

網(wǎng)上找到的答案是vjtag 200歐電阻上拉，vpump加電容。

這是原理圖。

可能是vjtag的問題，飛線比較難辦。
實(shí)驗(yàn)室的門開不開了，只好回家用自己的設(shè)備了。
以前是能開開的，唉，郁悶。

作者: wangkj 時(shí)間: 2009-6-27 10:10
還得給自己的電腦安裝軟件。

作者: wangkj 時(shí)間: 2009-6-27 12:03
另外的說法就是去掉r4,r5電阻。

作者: wangkj 時(shí)間: 2009-6-29 10:40
拆掉那兩個(gè)電阻，vjtag 加200歐姆電阻，故障依舊。
看來得找個(gè)usb的編程器了。
俺自己想辦法。不知道誰有賣的。

作者: wangkj 時(shí)間: 2009-7-1 12:16
用usb的燒寫器好了。
