#41431 - Help ! it's work's one time only |
i used p98c61x2 from philips in 24Mhz ,and it's just a simple program that clear the external dual port RAM and send out 1k bytes of data via UART port .this program can only run at the first time whan the power supply not off-line , after replugin the dc power (LESS THEN 0.5 SEC) the cpu just don't work any more(txd pin remain at Hi ) , the only way to let it work again is pull out the cpu from socket and put it back on circuit again than turn on the power, and if i turn off the power again it'll stop work again. some one said it's a "system lachout???" how do i fix it
thanks anyone for any information best regards chris chang |
