我在做uCLinux移植到Nios II 上的实验时,SDRAM用的是50MHz的时钟,相位用的是-135,其他用的都是100MHz。(开始都用的是50MHz的也不行)。还请高手指点下,不胜感激! 前面的编译没有问题,用flash progrommer的时候提示信息如下: Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Resetting and pausing target processor: OK Reading System ID at address 0x00C02050: verified : Checksumming existing contents 00000000 : Reading existing contents ..........(略) 000F0000 : Reading existing contents Checksummed/read 12kB in 0.8s 00000000 ( 0%): Erasing ..........(略) 000F0000 (93%): Erasing Erased 1024kB in 15.5s (66.0kB/s) 00000000 ( 0%): Programming 00002000 ( 0%): Programming 00004000 ( 1%): Programming 00006000 ( 2%): Programming 00008000 ( 3%): Programming 0000A000 ( 3%): Programming 0000C000 ( 4%): Programming 0000E000 ( 5%): Programming 00010000 ( 6%): Programming Program failed at offset 11BF3 Leaving target processor paused
