when my mcf54415 board is power on, spi flash sometimes can not bootload correctlly,and then i push the manual reset key of the sp706s IC(external watchdog is bypassed),spi flash can bootload correctlly.From analysizing the waveform,i find that mcf54415 reads about 30~50 bytes from spi flash and then stops when power on. i wants to know what's

wrong,hardware circuit or uboot program? thahks
