调试flash时,总是出现程序下载不进去,NISO提示如下错误:
Using cable "ByteBlasterII [LPT1]", device 1, instance 0x00
Resetting and pausing target processor: OK
Reading System ID at address 0x00A03018: verified

开发环境用的是Quartus II 5.1 NisoII—5.1
板子是自己仿制altera公司的
FPGA:EP2C8Q
SDRAM:K4S641632H
FLASH:AM29LV160D
单个调试SDRM时是可以通过的,但是单个调试FLASH时间就是要出现上面的问题,也不知道是不是和目标板有关,我采用的是EP2C35的目标板。
