使用spartan 6 xc6slx9 使用SPI方式的FLASH做PROM,使用impact通过 FPGA对SPI FLASH进行烧写,可以查出SPI FLASH,但是烧写配置文件时(.mcs)时,进行至7%时停止了,然后提示编程失败。
FPGA的DONE输出端口接了300Ω上拉,其余和数据手持基本一致。
信息输出提示如下:
'1': Programming Flash.
'1': Reading device contents...
done.
'1': Verification completed.
'1':Programming in x1 mode.

请问FPGA供电几秒钟之后电流突然增大是什么原因?
