| -- 作者：wangxinxin -- 發布時間：2010-11-25 13:52:38 -- SBC-2410X開發板不能啟動LINUX系統 系統采用REDHAT LINUX 9.0,按照手冊建立好開發環境，順利用Jflash 燒寫vivi 到Nand Flash.但在使用minicom通過xmodem協議使用load flash kernel x命令下載內核卻失敗(內核版本為zImage-yaffs-v6-6448,是光盤上所帶的，大小為894K)，提示信息如下所示： Retry 0: NAK on sector Retry 0: NAK on sector Retry 0: Retry Count Exceeded Transfer incomplete READY: press any key to continue... 然后在windows 2000 下通過超級終端使用load flash kernel x命令下載內核也失敗，信息如下： vivi> load flash kernel x Ready for downloading using xmodem...

Downloaded file at 0x30000000, size = 914560 bytes An image size is too large to write flash. wanted = 0x000c0000, loaded = 0x000df480 然后用load flash 0x00030000 0x000df480 x下載內核成功 vivi> load flash 0x00030000 0x000df480 x Ready for downloading using xmodem...
