jtag无法识别FPGA和SPI闪存

问答对人有帮助，内容完整，我也想知道答案 0 你好我使用Avnet Spartana6lx75t评估板它使用了主串行spi（4x）配置模式和jtag（间接spi配置模式）每件事情都很好，但突然间，当我想使用这块板时，我注意到jtag无法识别FPGA和SPI闪存幸运的是我没有在spi flash上清理工厂MCS文件，我将M0，M1引脚更改为主串口spi模式然后我注意到fpga完成了led开始，它开始正常工作它确保fpga没问题，我主板上的所有电源都可以我做了什么来找出问题所在 1 - 检查设备管理器中的Xilinx u*程序驱动程序（platforme cable u2） 2-将编程速度从6M改为3M，1.5M，750k 3 - 我的编程器绿色LED指示灯亮（VCC和GND连接正确） 4 - 我试过另一台PC XP和7 5-I尝试了3版ISE（13.1 13.4,14） 6-I用spartan3板改变fpga板，我看到jtage链与我的程序员正常工作 7-I检查我的jtag链是否确保电气关闭（有一个跳线，你可以扩展你的jtag链认为FMC连接器） 8-我在程序员和fpga板之间使用了两条不同的电缆（电缆没问题）解决了所有嫌疑人之后，我的问题仍未解决你知道问题可能是什么吗？没有人有任何想法？以上来自于谷歌翻译以下为原文 Hello I use Avnet Spartana6lx75t evaluation board It used master serial spi (4x)configuration mode with jtag (indirect spi config mode ) Every thing was good but suddenly when I wanted to use this board I notices jtag couldn’t not be able to recognize FPGA and SPI flash fortunately I didn’t clean factory MCS file on the spi flash , I changed M0 ,M1 pin to master serial spi mode then I notice fpga done led became on, it started to work properly it made a sure that fpga is ok , all the power led on my board is ok too what I made to find out what the problem is 1-checking the Xilinx u program driver in device manger(platforme cable u*2) 2- Changed speed of programing from 6M to 3M, 1.5M ,750k 3-my programmer green led is on( VCC and GND is connected properly ) 4-I tried with another PCs XP and 7 5-I tried with 3 version of ISE (13.1 13.4 ,14) 6-I change the fpga board with an spartan3 board and I saw jtage chain is work properly with my programmer 7-I check my jtag chain to be sure is electrically close(there is a jumper that you can extend your jtag chain thought FMC connector ) 8- I used two different cable between my programmer and fpga board (cable is ok) After solving all suspects my problem is still not solved Do you know what problem could be No one have any idea ? 0
