做了一个板子,前有两个版本,都能正常启动运行,但现在又改了一个版本,走线都没有什么变动,但是下载EBOOT和WINCE内核后启动WINCE时死机了,信息是: --------------------------------------- --- Configuring Chip Select 3 --- --------------------------------------- --- Desired timings --- --------------------------------------- dwNWE_SETUP 19 dwNCS_WR_SETUP 0 dwNRD_SETUP 19 dwNCS_RD_SETUP 0 dwNWE_PULSE 38 dwNCS_WR_PULSE 76 dwNRD_PULSE 38 dwNCS_RD_PULSE 76 dwNRD_CYCLE 76 dwNWE_CYCLE 76 dwClockPeriod_ns 19 --------------------------------------- --- Real timings --- --------------------------------------- ddwNWE_SETUP 19 dwNCS_WR_SETUP 0 dwNRD_SETUP 19 dwNCS_RD_SETUP 0 dwNWE_PULSE 38 dwNCS_WR_PULSE 76 dwNRD_PULSE 38 dwNCS_RD_PULSE 76 dwNRD_CYCLE 76 dwNWE_CYCLE 76
到这里就死起了,有时候是提示某一个块是坏的,NANDFLASH是K9F2G08,能不能排出电磁兼容的问题? |
